Notes: *The efficiency has been reduced to %70 due to usual decrease in efficiency that comes with brewing very high gravity beers. We can adjust this as needed.
*In regards to mash water volume, while many people go with 1.5 qts/lb of malt, we have always had success with a lower rate of 1 qt/lb. This may need to be adjusted.
*We have targeted a pre-boil volume of 16 bbls, but if evaporation is greater than this, let me know and we can adjust.
*Super moss/Whirlfloc have different usage rates. add at at rate that has been successful for Mare Island.
*Zinc usage rate has been increased due to increased gravity.
*Ferment at 66 degrees Fahrenheit. Ferment until final gravity doesn't change for at least 3 days in a row.
-Perform diacetyl test (notes to follow) daily until there is no diacetyl detected.
*After the beer is done fermenting, and passes a diacetyl test, drop the temperature of the tank to 35 degrees F. Allow to condition until the beer tastes ready.
*Hops can be substituted based on availability, though please consult with us before making substitution, as some varieties will not be appropriate to style.
*Hop quantity is based on Alpha acid indicated and a pre-boil volume of 16 bbls.
*Treat water as Mare Island does. |
