Hi there, after several years of making wine at home, I'm going to give all grain brewing. I will be using the Grainfather system and hot liquor tank. The last few days I have been reading as much as possible, but I do have a few questions. My first attempt at all grain brewing will be a 5 gallon Dogfish 90 clone recipe. There are a variety of hops in pellets and whole hop form. A total of 17lbs of Malt from the combination of Munich and Pale two-row. Below are the recipe directions. Thanks in advance.
"90 minute IPA clone is created with a single infusion mash at 150F for 60 minutes." Boil for 90 minutes adding hops in .2 ounce additions every 5 minutes for the duration of the boil.
So, first I need to get the steps right and hopefully my terminology isn't to far off.
1. The initial water for mash in at 1.25 qts water/ lb of malt. so, 1.25x17/4= 5.3 gallons of water.
that water will be heated to 150F and then malts are mixed in for 60 minutes at the 150F temp. with the recirculating pump on.
2. After 60 minutes, 170F sparge water will be added to the malt bed. I'm not sure how much will be needed, but I'm guessing adding what was lost to evaporation and absorption to get back to 5 Gallons?
Once sparge is complete and grains removed the pump will continue recirculation.
3. recirculate and bring to boil for 90 minutes. Hops will be added during this boil period. Would I be continuously adding sparge water throughout the 90 minutes to maintain the 5 gallon level?
?
4. After 90 minutes, the beer will go through the counterflow until the temperature of the wort is down to 72F and fermented at that same temperature.
Probably enough questions for now. I'm aware that irish moss or clarifying tabs can be added at some point.
