Keeping track of your water chemistry pays off with outstanding tasting beer!
If you have soft water and are brewing a hop forward beer, you’ll want some Gypsum on hand. Gypsum (calcium sulfate) is used to add permanent hardness to your brewing water in the form of calcium ions, which will increase the hop perception in your beer.
1 gram of Calcium Sulfate in 1 gallon of water changes the salt levels by 61.5 ppm calcium, 147.5 ppm sulfate and adds 153.5 ppm to the hardness.
This classic German hop has an herbal/floral character and smooth bitterness, making it an ideal choice for brewing lagers, especially traditional pilsners. Hallertau Mittelfruh is one of the original four Noble hops, and is categorized as a "landrace" hop, meaning that it grew and adapted naturally over time in its native region. Its name is derived from the region of Hallertau, the world's largest hop growing region, and the German word mittelfrueh meaning "middle-early", referring to the early middle part of the growing season when it's ready to be harvested. The majority of its oil content comes from Humulene which provides the floral, herbal, and spicy character. Clean, crisp, and perfect for your next pilsner or hoppy lager.
Hop Statistics:
Alpha Acids: 2.0 – 5.5%
Beta Acids: 3.0 – 5.0%
Alpha-Beta Ratio: 0.40 – 1.83
Cohumulone: (% of alpha acids): 23 – 26%
Total Oils in mls per 100 grams dried: 0.7 – 1.3

The HI84500-61 alkaline reagent is necessary for the analysis of total sulfur dioxide. The alkaline reagent raises the pH and liberates bound sulfur dioxide. This pH adjustment ensures that all of the free and bound sulfur dioxide is accounted for to give an accurate measurement of total sulfur dioxide. The HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges. The HI84500 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.
The HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:
IO3- + 5I- + 6H+ → 3I2 + 3H2O
The iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:
H2SO3 + I2 → H2SO4 + 2HI

Specially formulated cleaning solution to remove wine deposits from a pH electrode
Convenient, one-time use sachets ensure freshness of solution
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.
The Cleaning Solution Series ensures maximum efficiency and accuracy of your sensors when used for it’s designated application. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. The HI700635P is a cleaning solution made specifically for the wine industry, where electrodes can become coated with wine particulates and deposits found in juice and must.and must.

The Importance of pH in Wine Making
The pH of wine is important to determine because it will affect the quality of the final product in terms of taste, color, oxidation, chemical stability and other factors. Generally in winemaking, the higher the pH reading, the lower amount of acidity in the wine. Three important factors in determining the pH of wine include the ratio of malic acid to tartaric acid, the amount of potassium, and the total amount of acid present.
The edge HI2020W wine pH meter kit includes all the necessary supplies to determine the pH of wine must and juice accurately. The meter supplied with the HI2020W is the multiparameter edge, HI2020. The HI2020 is an advanced meter that is rich in features including using digital electrodes that can be swapped out anytime to switch to a different parameter, built in rechargeable battery, two USB ports, datalogging, automatic calibration, GLP (good laboratory practice) data for last calibrations, and Hanna’s exclusive calibration check feature that will alert the user to potential problems during calibration including when to clean the electrode and when the buffer might be contaminated. The HI2020 is a versatile pH meter for winemaking that be used as a benchtop, portable and even a wall mount to conserve space. The HI2020 is one of the most advanced meters available but the most important aspect in measuring pH is having the correct sensor for the application.
The HI2020W wine kit is packaged with the HI10480 (MT620Z) in place of the normally supplied HI11310. The HI10480 is a specially designed pH electrode that is resistant to clogging to the solids found in grape juice and must. This double junction, refillable pH electrode has a unique ground glass junction and PTFE sleeve to provide unsurpassed performance for the wine industry. A standard pH electrode will have a ceramic junction that can be easily clogged by solids. When this happens the pH readings will be erratic and drift over time before stabilizing on the actual pH value of the wine sample. The HI10480 with CPS technology will prevent the junction from clogging. The HI10480 is a digital electrode that when used with the edge HI2020 will change the default buffer set from pH 4.01and 7.01 to pH 3.00 and 7.01.
The edge HI2020W (MT620) wine pH meter (kit) includes the HI180-1 compact magnetic mini-stirrer. The use of a magnetic stirrer allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time of a sensor in achieving a stable reading.
The edge HI2020W wine pH kit also includes all the solutions for calibration and maintenance. In order to ensure the highest of accuracy in measurement it is important to bracket the calibration buffers around the expected reading. Since the pH of wine is less than pH 4.01 it is important to calibrate at a lower pH value. For calibration the kit includes the HI5003 (MT611) pH 3.00 and the HI5007 pH 7.01 technical calibration buffer. Each bottle of buffer NIST traceable is supplied with a certificate of analysis that includes lot number, expiration date and reference materials used in production.
For maintenance the The HI70635L cleaning solution for wine deposits and the HI70300L (MT631)electrode storage solution. When the “clean electrode” message is displayed during the calibration of the HI2020 edge or there is a poor probe condition (i.e. less than 30%) then soak the HI10480 in the cleaning solution for 15 minutes to clean any deposits from the glass surface. After cleaning the probe should be rinsed with purified water and then allowed to soak in the storage solution for 2-3 hours. The electrode storage solution is also used when the electrode is not in use. Either place a small amount into the storage cap or into a beaker in order to maintain a properly hydrated electrode.

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode.
Clogging Prevention System (CPS™) Technology
Refillable Electrode
Double Junction Design
Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.
General Purpose Glass Formulation
General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.
Spherical Glass Tip
The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.
CPS Sleeve Junction
Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.
Double Junction Reference
A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.
Refillable
The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.
Glass Electrode Body
The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature
dependent. The faster the equilibrium the steadier the reference potential.
BNC Connector
The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
Single Junction Versus Double Junction pH Electrodes
Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.
Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction.

Significance of Use
Unrefined wine is quite turbid and hazy from suspended solids produced during fermentation. The unrefined wine is treated with fining agents to reduce cloudiness. This cloudiness is what winemakers refer to as protein haze, or haze for short. Thaumatin-like proteins (TLPs) and chitinases are the primary grape proteins responsible for haze formation. These positively charged proteins degenerate and stick together, resulting in undesirable flocculent clouds and visible haziness.
The prevention of protein haze or deposit in bottled white wines is a universal concern and often a wine needs to be stabilized before bottling. One commonly used stabilization agent is bentonite. Bentonite is a volcanic clay earth type fining agent (like kaolin) that acts as a wine stabilizer. It improves the clarity of wine but has also negative aspects because of the volume of lees formed, reduction of tannin and color. Since there are different types and qualities of bentonite with different capacity of protein removal, it is important to make laboratory trials with the same lot and wetting degree of the bentonite as that will be used in the cellar.
Protein stabilization is normally not a problem in bottled red wines because of the relatively high concentration of phenols that binds and precipitates with the unstable proteins before bottling. Often bentonite is added to red wines at a level of about 12 g/hL (1 lb/1000 gal), reducing colloidal suspended particles thus improving membrane filterability.
Wines with low phenols contents, such as rose, light reds and whites should be checked for protein stability before bottling. Hanna offers a rapid test to verify the risk of future protein haze formation. If protein instability is detected, a next test can help defining the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite, avoiding stripping wine flavour, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability results in a reduction of costs.
Winemakers can determine the initial turbidity of the unrefined wine with the HI83749 turbidity measurement instrument. After taking a turbidity reading the pre-made HI83749-20 Bentocheck Solution is added to the wine sample. A second turbidity measurement is taken. If the second turbidity reading is less than the initial turbidity reading plus 2 NTU, the wine can be considered stable. Otherwise a fining trial can be performed to determine the amount of bentonite that must be added to stabilize the wine.
Principal of Operation
To measure turbidity the HI83749 passes a light beam through the sample that is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI83749 includes a tungsten filament lamp, a scattered light detector (90°) and a transmitted light detector (180°).
The HI83749 features a powerful microprocessor that calculates the NTU value from the signals that reach the two detectors. An effective algorithm is used to correct and compensate for any color interferences. The optical system and measuring technique also compensate for fluctuations in lamp intensity, minimizing the need for frequent calibration.
The HI83749-11 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials. These standards are used for calibration and performance verification of the turbidity meter.

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode.
Clogging Prevention System (CPS™) Technology
Refillable Electrode
Double Junction Design
Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.
General Purpose Glass Formulation
General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.
Spherical Glass Tip
The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.
CPS Sleeve Junction
Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.
Double Junction Reference
A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.
Refillable
The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.
Glass Electrode Body
The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.
BNC Connector
The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
Single Junction Versus Double Junction pH Electrodes
Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.
Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction.
Able to measure samples 0 - 80C
Glass body, refillable sleeve junction PH electrode with a BNC connector
Features a double junction reference with Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass
Ideal for wine must and juice due to high solid content that would clog a standard general purpose PH Electrode
Replacement Hardness test reagent 5 (15 ml) with a 12 month shelf life Does not include complete BrewLab test kit. See BrewLab Basic® test kit or BrewLab Plus test kit for additional information.

Liquid Malt Extract (LME) vs. Dried Malt Extract (DME)
MoreBeer! recipe kits are offered in both Liquid Malt Extract and Dry Malt Extract so that our customers can choose the format that best suits their needs and brewing style. LME is a viscous liquid, similar in consistency to maple syrup. In addition to being the more affordable option, many brewers find LME easier to handle than dry extract. DME is more condensed and comes in a powder format that is similar to baking flour. Although it’s a little more costly, DME is naturally lighter in color and stays fresher for longer. We highly recommend DME when brewing light colored beers.
Bursting with hop character with a smooth and creamy mouthfeel. Our best-selling Hazy IPA year after year

Haze Craze is our take on the hazy New England IPA recipe. Also known as a North Eastern IPA, or Juicy IPA, it quickly became one of the most popular beer styles in the US. It packs all of the hop character that craft beer nerds love, and it's much softer and less bitter than classic West Coast IPAs, making it a much more approachable style for the uninitiated. The style accentuates hop character while maintaining a smooth and creamy mouthfeel. Light in color but hazy due to heavy dry hopping, yeast selection, as well as additions of oat and wheat. Low in bitterness with a huge hop character due to hop-bursting, this beer will satiate even the biggest hop head.
NEIPA has become popular nationwide thanks to breweries like Tree House Brewing, The Alchemist, Hill Farmstead and Grimm Artisanal Ales. One taste of this delicious style will make a staple in your brew schedule.
