Cleaves (Chops!) thiols releasing citrus, passionfruit, grapefruit, floral flavors Ferment at 58-61 for maximum enzymatic activity #1 Choice for Sauvinon Blanc. Also good for Viognier Oh thiols, you elusive magical compound. Nice try hiding behind Cysteine-4mmp, but CITRUS sees you. Cleaving thiols from other compounds is what CITRUS does, releasing the classic citrus, lime, passionfruit, and floral flavors that help separate styles like Sauvignon Blanc and Viognier from ordinary white table wine. Also can be used with Chardonnay , other whites, and is great for Rose. CITRUS can ferment at cooler temperatures but the enzymatic cleaving activity is highest at around 56-60F. So if you like Zesty Grapefruit, lime, lemon peel, floral, and passionfruit flavors, CITRUS may be your yeast. This yeast is good and perserving acidity so if you are working with whites from a warmer region that can be particularly helpful. More on Thiols: Thiols are organic sulphur compounds that are resonsible for the most prized flavors in many white wines. 4mmp (black current), 3MH (Passion fruit, Grapefruit and Citrus) and 3MHA (Tropical Passionfruit, Rose) Start Time: Average Alcohol tolerance: 14%+ Nitrogen Demand: low Production of volatile acidity: Average Production of H2S: Average Production of SO2: Low Ease to Ferment with MLF: Good Optimal Fermentation Temp: 53–73°F (Ideal for enzymatic activity: 56–60°F) Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.

MAISON is a Belgian yeast strain designed for a wide range of Belgian-style beers including Belgian Blondes, Witbiers, Dubbels, Tripels, and Quads
Produces classic fruit esters alongside subtle clove and spice phenolics, achieving the perfect balance of fruit and spice for authentic Belgian character
Designed to be sprinkled directly onto the surface of your wort with no pre-oxygenation before pitching required
Ferment between 64-75°F
MAISON is your go-to Belgian yeast strain, crafted for a wide range of Belgian-style beers including Belgian Blondes, Witbiers, Dubbels, Tripels, and Quads. MAISON ferments effectively across a broad temperature range, producing an expressive yet refined balance of esters and phenols typical of classic Belgian fermentations.
At higher temperatures (around 75°F / 24°C), expect robust flavor development, featuring moderately sweet malt supported by bright fruit esters such as ethyl hexanoate (pear, apple) and isoamyl acetate (banana). These are complemented by gentle clove-like phenols (4-vinyl guaiacol) and subtle notes of white pepper and coriander seed, creating a complex yet clean Belgian profile.
At lower temperatures (around 64°F / 18°C), MAISON presents these same characteristics with greater restraint—producing a more nuanced and elegant fermentation signature. The fruit esters become softer and more floral, while phenolic spice is dialed back, allowing malt sweetness and smoothness to shine through.
Flavor Profile: Moderately sweet malt with notes of pear, soft apple, banana, clove, white pepper, and a touch of toasted-bread malt character.
Primary Compounds: Balanced production of ethyl hexanoate and isoamyl acetate, with light phenolic expression from 4-vinyl guaiacol for a classic Belgian balance of fruit and spice.
Flocculation: Low to Medium
Fermentation Range: 64–75°F (18–24°C)
Alcohol Tolerance: 12% ABV
Apparent Attenuation: ~75–80%
Direct Pitch: No rehydration necessary
Reliable & Consistent: Every batch undergoes PCR testing for verified strain purity and performance consistency
High Cell Count: 15 g per sachet — over 36% more yeast than standard 11 g packs
Versatile for All Brewers: Ideal for both homebrewers and professional craft brewers seeking authentic Belgian flavor with modern reliability
Dosage:
One sachet treats a 5–6 gal (19–23 L) batch. For larger batches, use 2–3 g/gal (0.5–0.8 g/L). We recommend rounding up by one full sachet for consistency.
Like all CellarScience yeast strains, MAISON offers professional-grade performance and precision delivering consistent results, expressive flavor, and exceptional value.
Scottzyme PEC5L – Pectinase Enzyme for Enhanced Settling and Juice Yield
Rapidly breaks down soluble pectins for faster settling and improved clarity
Increases free-run and press yield by reducing viscosity and cell wall resistance
Improves flotation efficiency and tightens lees compaction
Effective across a wide pH range and performs well at low temperatures
Ideal for white, rosé, and fruit wines requiring fast clarification and clean separation
Scottzyme PEC5L is a highly active liquid pectinase enzyme formulated to reduce pectin-related haze and increase processing efficiency in juice production. By breaking down soluble pectins, PEC5L dramatically improves juice release during pressing, reduces must viscosity, and accelerates settling or flotation. The result is clearer juice, more compact lees, and higher overall yield. Its formulation is optimized for cool-temperature performance and a broad pH range, making it a versatile tool in grape and non-grape juice clarification. Unlike general pectinases, PEC5L is designed to act quickly and cleanly, without over-extraction of phenolics or bitterness.
Protocol
Dilute Scottzyme PEC5L in 10 times its volume of chlorine-free water or juice. Add to must or juice immediately after crushing or during transfer to settling tank. Mix well to ensure even distribution. For flotation, add just before or during the flotation process. Avoid adding at the same time as SO₂ or bentonite.
Usage Rates
Recommended dosage: 1.5–4.0 mL per 1000 lb of fruit or 0.075–0.2 mL per gallon of juice
= approximately 0.02–0.05 mL per liter
Use lower rates for clean, low-pectin fruit or warmer temperatures. Use higher rates for pectin-rich grapes, low temperatures, or difficult-to-settle musts. Allow contact time of 2 to 12 hours depending on conditions and desired level of clarification.

F-2 was specifically selected for secondary fermentation in bottle and in cask
Neutral aroma profile and high alcohol resistance make it perfect for refermentation bottle conditioning
Sticks well at the bottom of the bottles/casks
Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world
SafAle™ F-2 is specifically selected for secondary fermentation in bottle and in cask. This yeast assimilates very little maltotriose but assimilates basic sugars (glucose, fructose, saccharose, maltose) and is characterized by a neutral aroma profile respecting the base beer character. Its neutral aroma profile, high alcohol resistance and stickiness characteristics make it a perfect match for consistent re-fermentation in bottle and cask.
SafAle™ F-2 resists to high alcohol levels (>10% v/v) and allows brewers to obtain all the properties of refermentation such as:
Beer preservation thanks to oxygen trapping
Contribution in roundness and maturation aromas
Carbonation
Sticks well at the bottom of the bottles/casks and forms a nice haze when it is resuspended
Usage:
Add 19 to 38 grams of sugar per gallon of beer (5 to 10 grams of sugar per liter) to obtain a saturation of 2.5 to 5.0 g/l of CO2
Pitch the sweetened beer, that should be at fermentation temperature (68-77°F / 20-25°C) with the rehydrated yeast. Carbonation will be achieved in 1 to 2 weeks at 68-77°F. Carbonation at 59°F can take over 2 weeks
At the end of refermentation, the beer can be cooled down and will gain in roundness after 2 to 3 weeks
Please note: Example image shows a 20g sachet. The correct size is 25g. Updated image coming soon.

Emphasizes red berry fruit flavors High color extraction Makes wines that do not require extended aging Med-High nutrient need Top choice for Zinfandel, Sangiovese, Pinot, Merlot Our most popular red yeast is a perfect choice for Pinot Noir, Zinfandel, Sangiovese, Merlot and other reds where you want to emphasize red fruit flavors. When compared with BIG RED or PURPLE, RED is less about structure and body and more about fruit. Fantastic by itself if you plan to blend separately fermented lots back together. RED is a great choice to contribute red berry flavor. Also known to help produce intense color. Also a great choice for Cabernet, Syrah and other traditinoal big red varietals where you would like to emphasize fruit over structure and body. Because RED ferments cleaner than most yeast at high temperatures, it is the perfect choice if you are fermenting in a warm environment and do not have temperature control. It does not produce much SO2 so it is a great choice for easier ML fermentations Start Time: Average Alcohol tolerance: 16% Nitrogen Demand: Med Yan Requirement @ 23 Brix: 250ppm Production of volatile acidity: low Production of SO2: Low Ease to Ferment with MLF: Good Yeast Type: Cerevisiae Killer Factor: Neutral Malic Acid Consumption: Average Optimal Fermentation Temp: 65–85°F Proper yeast hydration helps ensure a healthy fermentation.

Recomended for aged red wines High color extraction Significant polysaccaride and glycerol production for huge mouthfeel High alcohol tolerence High nutrient need Top choice for Bordeaux varietals Cabernet, Cab Franc, Petite Verdot and Merlot Also excelletnt for Sangiovese, Nebbiolo and some Pinot The name kind of says it all. BIG RED is ideal for producing big, complex red wines with lasting fruit. Depending on the grape varietal used it can emphasize complex berry fruit and spice flavors. This strain is very efficient at breaking down and extracting tannins and anthocyanins from grape skin walls, making wines with dark inky color and a tannin profile suitable for extended aging. BIG RED also produces a great mouthfeel due to the significant production of polysaccharides and glycerol. It is also tolerant to higher alcohol levels making it ideal for those grapes that need to stay on the vine just a little longer to get full phenolic ripes with smooth tannin profiles. So lets recap... emphasizes berry fruit with many varietals, produces dark color, extracts a full array of tannins suitable for extended aging, makes wines with great mouthfeel, and is resistant to higher alcohols. Is there a catch? No, but to get all that done BIG RED does love nutrients and you will need to feed it and pay attention to it during fermenation. This is a strain where you would ideally know your Free Available Nitrogen levels that you could base a nutrient schedule around. Absent those numbers or a history with the grapes you are fermentiing, we would suggest you start with hydrating with Fermstart, feeding with FermFed DAP free at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. BIG RED is a very low producer of H2S when nutrient demands are met. The perfect strain if you want to make amazing reds. Not the perfect strain if you have a vacation planned during the middle of fermentation and are going to ask your neighbor to punch down...we hear it all!. Because this strain respects varietal character it can be used for a broad spectrum of red grape varietals. Perfect of courese for those Bordeaux varietals ilke Cabernet Sauvignon, Cabernet Franc, Petit Verdot and even Merlot. Also our first choice for Nebbiolo and some bigger style Sangiovese and Pinot Noir. Start Time: Fast Alcohol tolerance: 16%+ Nitrogen demand: high Yan Requirement @ 23 Brix: 270ppm Production of volatile acidity: Low Production of SO2: Low Ease to Ferment with MLF: Average Yeast type: Cervisiae Killer Factor: Neutral Malic Acid Consumption: Average Optimal Fermentation Temp: 65–85°F Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.

Enoferm Beta can positively contribute to the sensory profile of the wine, by enhancing spicy and red fruit aromas Delected due to it's good performance under difficult wine conditions and positive sensory contribution Able to induce MLF at temperatures as low as 55°F Lallemand Oenology specializes in the development, production, and marketing of top-grade yeast and bacteria Enoferm Beta is a single strain of Oenococcus oeni (ex Leuconostoc oenos), isolated from a Cabernet Sauvignon wine from Abbruzzi. It was selected due to it's good performance under difficult wine conditions, positive sensory contribution, and security from its low use of sugars and very low volatile acid as well as biogenic amines production. In winery trials, Enoferm Beta was able to induce MLF at temperatures as low as 55°F. Most direct inoculum preparations have difficulty completing MLF unless temperatures > 64°F, while Enoferm Beta can be used in wines with temperatures > 57°F. For more information about ML Bacteria, please see MoreWine!'s Guide to Malolactic Fermentation. 2.5 g: good for 66 gallons 25 g: good for 660 gallons Alcohol tolerance: <15% v/v. SO2 tolerance: <60 ppm pH: >3.2 Temperature: >57°F Different lactic acid bacteria strains do have an impact on the flavor profile of wine, Enoferm Beta can positively contribute to the sensory profile of the wine, by enhancing spicy and red fruit aromas, low diacetyl production, better structure and body,and less astringency and bitterness. You can't store malolactic bacteria once the package has been opened. Note: Malolactic bacteria added during the ferment will compete with the yeast for nutrients and are atagonistic to yeast, potentially resulting in higher VA levels. The best time to add an ML culture is after racking off the gross lees.

WLP675 is a direct pitch liquid Malolactic culture for 6 gallons of wine
Tolerant of a wide range of temperatures and pH—perfect for home winemakers
Leaves no significant impact on flavor, aroma or mouthfeel
WLP675 is a direct pitch liquid Malolactic culture for 6 gallons of wine. This ML culture from White Labs is specially designed to meet the needs of home winemakers. It is tolerant of a wide range of temperatures and pHs and will not have a significant impact on flavor, aroma or mouthfeel.
Vital Stats:
pH tolerant down to 3.0
Low temperature tolerant down to 55°F
Alcohol tolerant to 15% ABV
Free SO2 should be less than 10ppm
Please Note: White Labs recommends pitching this strain at around 5 Brix remaining sugar in your primary fermentation.

Produces ß-glucosidase to cleave terpenes Floral, Rose, Citrus flavors Will not produce volatile phenols Best choice for Muscat/Moscato & Gewurztraminer. Also great for Sauvignon Blanc, Riesling and Viognier Those floral, rose, citrus, and stone fruit aromatics are bound all up in terpense in your grape skins and you know, they would really like to get out. It's your job to free them, package them in a bottle, and eventually let them waft out of a wine glass and into the nasal cavity of someone who appreciates excellence. We can help you do this. If you are making a higly aromatic white such as Muscat, Gewürztraminer, Viognier, Sauvignon Blanc or Riesling this is the ideal yeast. BOUQUET is known for its production of the enzyme ß-glucosidase which liberates aromatic compounds by cleaving terpenes from the sugars that bind them and releasing their goodness. This yeast will turn these certain grape varietals from ordinary white wines to highly aromatic, very special white wines that smell and taste amazing. The type of wine where 'stuff' wafts out of the glass! Also interesting is that most yeasts have the potential to produce phenolic off flavors, which in high quantities produce a paint like aroma (yuck!), if the conditions are less than ideal. However, BOUQUET is POF (phenolic off flavors) negative and will synthesize phenolic off flavors, eliminating that risk. This is a great yeast to co-ferment with Luscious for added complexity. Additional Fermfed nutrient is recommended at the start of fermentation due to the short lag phase of this strain. Due to such a rapid period of growth, the yeast cells require higher levels of nutrients to ensure a healthy fermentation. If you have had your wine tested and know your Yeast Available Nitrogen (YAN) follow our CellarScience nutrient feeding schedule accordingly. If you don't know your YAN we recommend hydrating with Fermstart, feeding with FermFed at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. Normally the feeding at the onset of fermentation would be with Fermfed DAP free but in this case BOUQUET can use the extra DAP kick that Fermfed provides. Start Time: Fast Alcohol tolerance: 14% Nitrogen demand: Very High Yan Requirement @ 23 Brix: 340 ppm Production of Volatile Acidity: Low Production of SO2: Average Cap/Foaming: Average Ease to Ferment with MLF: Low Malic Acid Consumption: Average Killer Factor: Positive (though is able to coferment with Luscious) Yeast Type: Cerevisiae Optimal Fermentation Temp: 50–80°F Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.

cottzyme KS – High-Power Enzyme for Complex Pectin Breakdown in Red, White, and Problem Wines
Breaks down complex, highly esterified pectins that standard pectinases cannot
Enhances clarification, settling, and filterability in challenging juices and wines
Boosts juice and wine yield by improving extraction from thick-skinned or high-pectin fruit
Ideal for problem fermentations or hazy wines that resist fining and filtration
Performs well at low temperatures and in a broad pH range
Scottzyme KS is a specialized pectolytic enzyme designed to break down complex pectin structures found in high-pectin varietals and difficult ferments. While standard enzymes like PEC5L target simple soluble pectins, KS is formulated with enhanced side-chain cleaving activity that attacks esterified pectins and heavily branched structures. This makes it particularly effective on cultivars like Pinot Gris, Riesling, Gewürztraminer, Muscat, and in juice or wine where haze persists despite prior enzymatic treatment. KS improves clarification, tightens lees, increases press and wine yields, and boosts filtration efficiency—especially in wines that defy typical settling protocols.
Comparison to Scottzyme PEC5L:
Scottzyme PEC5L is a fast-acting general-purpose pectinase for typical clarification tasks, such as settling and flotation of white and rosé juices. It’s ideal for clean juice production from standard grapes and most fruit wines. In contrast, KS is the go-to choice when PEC5L isn’t enough—it’s stronger on stubborn, esterified pectins and delivers better results with problematic varieties or ferments that remain hazy even after PEC5L. While PEC5L is excellent for fast juice prep, KS excels in the most difficult cases, including post-fermentation haze and challenging press fractions.
Protocol
Dilute Scottzyme KS in 10 times its volume of chlorine-free water or juice. Add to must, juice, or wine and mix well. Suitable for use before or after fermentation. Do not add simultaneously with bentonite or high SO₂. Works effectively at 10–20°C.
Usage Rates
Recommended dosage: 1.5–4.0 mL per 1000 lb of fruit or 0.075–0.2 mL per gallon
= approximately 0.02–0.05 mL per liter
Use lower rates for moderate haze and extended contact time. Use higher rates in cold settling, high-pectin juices, or persistent post-fermentation hazes. Allow 4–24 hours of contact time depending on application.

Autolyzing, quick release of polysaccarides such as mannoproteins Top choice for sur lie aging Ability to ferment cold for clean flavor with emphasis on mouthfeel and toastiness of sur lie aging When fermented warmer exoctic tropical flavors shine Frequently used to make luscious Chardonnays and similar white wines Luscious Chardonnays with creamy mouthfeel and deep complexity... if that is your end point, LUSCIOUS is your starting point. LUSCIOUS can be fermented at different temps depending on your style preference. Ferment it cooler, it can handle it, and put the emphasis on the creaminess and the toasted champagne-like complexity of sur lie ageing. Or crank it up a bit warmer and add in some more tropical notes, your choice. However the magic of LUSCIOUS really happens after fermentation when this yeast goes naturally goes nuclear, implodes and breaks open its cell walls, during a process called autolysis. Polysaccharides such as mannoproteins are released into the wine... and man, it's all about those mannoproteins creating that rich, creamy mouthfeel that so many Chardonnay drinkers seek out. The silky richness is emphasized even futher by sur lie aging, aging on clean lees for a period of time, in either tank or barrel. Being a low producer of SO2 it is naturally great candiate for later malo-lactic fermentations. Now that we have painted a picture try putting this marketing wizardry on your next label "The 10-40w viscosity of this wine is due to it being loaded with mannoproteins from the guts of exploded yeast cells". Maybe leave us out of the wine marketing department but we do know a winning yeast when we taste it. #1 for this style of Chardonnay but also a top choice for Viognier and other whites.

Northern IPA
The Northern IPA utilizes a high attenuation ale strain fermented at cooler temperatures to achieve a flavor profile that clean, crisp and dry. Compared to WCIPA or New England IPAs, the Northern IPA presents as dryer and more drinkable with the low specialty malt usage. The resulting beer character should be refreshing.
Malt profiles should be stripped back, with dominantly pale base malts to be sued, and avoiding high-kilned specialty malts altogether. Hop profile tends towards the juicy sweetness and biotransformation character of hazy IPAs, but to finish with a firm bitterness. May use hops from any origin but should showcase modern and hop=-forward hop characteristics not seen in traditional styles.
Overall impression to be a well-integrated hop-forward IPA style with clean but present yeast character which elevates with modern varietals.
See below for the Northern IPA style guidelines.

ProElif QA23 is a double encapsulated yeast product developed by Proenol for secondary fermentations. The yeast cells are double encapsulated in an alginate bead. The beads can be directly inoculated into the bottle (eliminating the need to prepare a starter culture). This helps ensure control of the number of cells per bottle. Upon fermentation completion, the beads have a greater density than the wine and will quickly drop to the neck of the bottle when inverted. The beads accumulate more tightly than traditional riddling, therefore less wine is lost during disgorging. Traditional freezing and disgorging methods are used to finish the process. The use of ProElif QA23 results in a fresh sparkling wine. If greater yeast character is desired, you may make changes to the base wine with this in mind. For example, ProElif QA23 has been used with Opti-WHITE treated base wine with good results.
The base wine must be stable to avoid agglomeration of the beads which could cause subsequent difficulty during disgorging. All of these parameters act in synergy with one another. It is critical to manage them together. If one parameter is over the limit, try to compensate with the others or ferment at a higher temperature.
Use at a rate of 2g/L. For full directions see the handout in the documents tab above.

Double pitch size with a minimum of 200 billion cells—twice the size of the standard yeast pitch
Imperial Yeast is a group of hard-working, fermentation fanatics who provide the brewing industry with the highest quality, most effective yeast possible
The Kveiking blend thrives in hot fermentations when big complex ester profiles are desired. A low pitch rate can be used to drive these aromatics even higher but the brewer should ensure this low pitch rate can be combined with a continuously high fermentation temperature. If the temperature drops too low, the corresponding level of attenuation can be low, with high terminal gravities. This blend contains flocculent and non-flocculent yeast strains, therefore the clarity of the final beers produced can be variable. Use this blend for anything from new school hazy IPAs to traditional Norwegian farmhouse brews. The Kveiking blend also works well when fermenting kettle soured worts for a strong tropical fruit character.

KÖLSCH yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels. KÖLSCH yeast is pre-loaded with essential nutrients to ensure a successful, complete fermentation. While not required, some brewers prefer to rehydrate yeast. To hydrate yeast, first, sanitize the yeast brick and scissors. Use 10 grams of sterilized tap water between 85-95°F (29-35°C) mixed with 0.25 grams of FermStart per gram of yeast. Sprinkle yeast on the water. Allow the slurry to stand undisturbed for 20 minutes, then swirl. Use small amounts of wort to adjust to within 10°F (6°C) of wort temperature before pitching. Ferment between 60-73°F (16-23°C).
