The recipe is:
Batch Size: 5 gal all-grain, single infusion mash, 120 min boil
Target Original Gravity: 1.096 (23 Plato)
Mash Efficiency: 65%
Mash Ingredients:
22.0 lb American 2-Row malt
2.0 lb 45L Crystal malt
0.13 lb Roasted Barley
Mash Temp: steep at 152F for 60 minutes
Kettle Ingredients:
2.25 oz Chinook (13.0%) pellet hops, 120 minutes
1.5 oz Centennial (8.8%) pellet hops, 30 minutes
0.2 oz Irish Moss, 15 minutes
1.5 oz Cascade (5.8%) leaf hops, 10 minutes
Ferment at 68F with American Ale (1056) yeast until final gravity settles to 1.024 (6.0 plato)
0.5 oz Centennial, 0.5 oz Cascade, and 0.5 oz Chinook Dry Hops in secondary fermentor
Carbonate to 2.5 – 3 volumes of CO2 (medium-high) and enjoy!
I have 4 heat elements totaling 18 KW of ULD elements. By running these elements at 1/4 t0 1/3 capacity plenty of heat is developed to boil. I too am concerned with scorching and having proper coverage to prevent damaging the heat elements. Not a problem. At a medium boil I evaporate about 1 gallon of liquid/hour and usually maintain the boil until either the proper volume or SG is reached. In the case of the high gravity beer and the larger initial boil can I use the same proceedure ? I realize the boil time may be 3, 4 or even 5 hours. I think I'm OK but not sure. Better to ask a dumb question than make a dumb mistake.
