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.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Great clove phenolics
This is my favorite weizen yeast. It produces wonderful clove phenolics with subtler fruit (banana) esters. Great in both traditional and dunkel- weizen. I won my homebrew club's dunkelweizen competition with this yeast. Powerful fermentation character with a 68 degree fermentation. Leaves a hazy beer, but that's what the style is all about.

The other producer makes this only in a seasonal strain.
