Flavors from this yeast vary greatly with the beer produced. The higher the gravity, the more winey the result. Beers over 16% ABV begin to taste less like beer, and more like fortified wines. With low gravity beers, this yeast produces a nice, subtle English ale-like ester profile. As the gravity increases, some phenolic character is evident, followed by the winey-ness of beers over 16% ABV. Most fermentations will stop between 12-16% ABV unless these high gravity tips are performed:
Aerate very heavily, 4 times as much as with a normal gravity beer. Less oxygen dissolves into solution at high gravity.
Pitch 3-4 times as much yeast as normal.
Consider aerating intermittently during the first 5 days of fermentation. This will help yeast cells during a very difficult fermentation. Aerate with oxygen for 30 seconds or air for 5-10 minutes.
Higher nutrient levels can allow yeast to tolerate higher alcohol levels. Use 2 times the normal nutrient level. This is especially important when using WLP099 to make wine and mead, which have almost no nutrient level to begin with.
Do not start with the entire wort sugar at once. Begin fermentation with a wort that would produce a 6-8% beer, and add wort (it can be concentrated) each day during the first 5 days. This can be done together with aeration. This is mandatory if the reported 25% ABV is to be achieved.
Attenuation: 80; Flocculation: Low; Optimum Ferm. Temp: 69-74 oF
We include a FREE gel ice pack with every order of liquid yeast. There is no need to order free gel ice packs...they're automatically included. We will include one ice pack for every six yeast ordered. If you wish an order to ship with more than 1 ice pack for every six liquid yeast, you may order extra**
**We recommend you do not order more than 1 ice pack for every 2 yeasts ordered. Ice packs are frozen when shipped, and there is a danger of frozen yeast.
