Super High Gravity WLP099
Can ferment up to 25% alcohol. From England. Produces ester character that increases with increasing gravity. Malt character dominates at lower gravities.
Optimum Fermentation Temperature: 65-69°F
Alcohol Tolerance: Very High
Notice to brewers: This can be a difficult-to-use strain and we recommend the following::
1. Needs heavy aeration.
a. Aerate very heavily, 4 times as much as with a normal gravity beer. Less oxygen dissolves into solution at high gravity. Aerate intermittently during first 5 days of fermentation (30sec-1min).
2. Needs nutrients
3. To obtain higher ABVs (16% +)
a. Pitch 3-4 times as much yeast.
b. Add 2 times the normal nutrient level
c. Begin Fermentation with wort that would produce a lower alcohol beer (6-8%) and then add wort each day for the first 5 days (wort can be concentrated at this point).
