Wyeast Warranty
Our Product Warranty states that we guarantee the viability of the yeast in our Activator™ packages for 6 months from the manufacture date assuming that they have been properly shipped, stored and handled. Our superior packaging material provides 100% oxygen barrier and UV light protection making this exceptional guarantee possible. During this 6 month guaranteed shelf life, some loss of viability is to be expected. This will vary from one strain to another. Activator™ packages that are 4 months old or older may require additional time to swell after activation.

Activator™ packages will sometimes swell slightly, or moderately during shipping or later while properly stored. This is not an indication of deterioration if the package is less than 6 months old and has been properly handled. This is result of trace amounts of nutrients, still available at the time packaging, causing small amount of culture activity and CO2 production. Some strains are more prone to this than others.

    1 review

    3638 is a complex alternative to the standard German wheat strain profile, producing apple, pear, and plum esters in addition to the dominant banana character Esters are complemented nicely by clove and subtle vanilla phenolics Activator Smack-Pack System™ "proofs" the yeast and shortens lag time when it hits your wort When smacked, the Activator™ packet releases sugars and nutrients to initiate the culture's metabolism Wyeast has been a pioneer in craft brewing for over 35 years and is committed to creating the finest fermentation products available Although beneficial, cultures do not need to be activated prior to inoculation A great all around German wheat beer strain! A complex alternative to the standard German wheat strain profile. This strain produces apple, pear, and plum esters in addition to the dominant banana character. The esters are complemented nicely by clove and subtle vanilla phenolics. The balance can be manipulated towards ester production through increasing fermentation temperature, increasing the wort density, and decreasing the pitch rate. Over pitching can result in a near complete loss of banana character. Decreasing the ester level will allow a higher clove character to be perceived. Sulfur is commonly produced, but will dissipate with conditioning. This strain is very powdery and will remain in suspension for an extended amount of time following attenuation. This is true top cropping yeast and requires fermenter headspace of 33%. Attenuation: 70-76% Flocculation: Low Alcohol Tolerance: 10% Optimum Fermentation Temp: 64-75°F Cell Count: 100 Billion Styles: Weissbier Dunkles Weissbier Weizenbock Roggenbier For best results we always recommend ordering an ice pack with your liquid yeast.
