Mash Schedule


Notes
mash water salts
1 tbsp buffer 5.2
3.6 grams chalk (.3 grams per gallon)
4.8 grams gypsum (.4 grams per gallon)
* the goal is about 50 ppm of calcium for yeast growth
whirlfloc at 30 minutes
wyeast nutrient at 10 minutes

Mash Schedule 1.2 quarts/gallon

145 beta amalayze rest for 30 minutes
152 alpha amalyze rest for 30 minutes
165F mash out for 15 minutes


48% efficiency = very low because this is using the no-sparge method.

** Remember to add 2 gallons to the Polarware mash tun to make up for the floor space below the false bottom

Hop schedule includes store purchased hops only.
4LB of fresh, homegrown hops were added starting at 15 minutes,
4oz each minute up until flame out, with 2 oz. added at flame out.

Homegrown hops were a mix of Chinook, Nugget, Centennial and Cascade.

fermentation procedure:
10 gallon conical with 2liter WLP001 yeast starter.

ferment at 66-68F, 6-7 days maximum,
diacetyl rest at 70F for 24 hours
drop the temperature to 52F for 2 days to pull the yeast out set the max temperature back to 68F and start the 12 day dry hopping at this point, letting the temperature slowly creep back up to 68F over a few days. Leave it at 68F for the bulk of the dry hopping regiment. 8oz. of wet hops from the same crop added for dry hopping. Drop it down to 33F for transfer 11 days into the dry hopping, so do about 1 day of cold conditioning before transferring it to the serving tank. Very gently stir the dry hopping additions to keep the hops in suspension
