Super High Gravity Ale Yeast - White Labs
|
Can ferment up to 25% alcohol. From England. 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.
White Labs take pride in producing the best liquid yeast on the market. Each strain is carefully grown under sterile laboratory conditions to high cell counts, and concentrated into each vial.
Each vial of White Labs liquid yeast is designed to be used directly in 5 gallons, or "pitchable". Each vial is equivalent in cell count to a pint starter, or 30-60 billion cells. One vial will usually start fermentation in 5 gallons in 5-15 hours at 70°F. If a faster start is desired, or if initial gravity is over 1.070, we recommend a 1-2 pint starter be made.
Homebrewers that enjoy yeast culturing- If a starter is made from a fresh vial, one vial can be added directly to a 2 liter starter, which in 2 days will grow to approximately 240 billion cells, to achieve a pitching rate in 5 gallons of 1 million cells/ml/degree Plato (with a 12 Plato beer).
