I don't have the exact recipe, but I do have one that is close enough to start with and keep trying with.
Harvest Clone (Base) 5 Gallon
10 lbs 2-Row Pale Malt (Or could use 6 lb Pale, 4 lb Maris Otter)
2 lbs Crystal 40L
8 oz Carafoam
1.25 oz Brewers Gold - 60 min
1 oz Columbus - 20 min
1 oz Nugget - 20 min
1 oz Challenger - First Wort (7 min)
1 pkg Wyeast 1056 - American Ale (Made into a 1.7L starter)
Mash 18.13 quarts @ 163°F for a Mash Temp of 152°F. Mash for 60 minutes. Fly sparge 2.91 gallons @ 168°F.
Primary fermentation 6 days. Transfer to secondary for 14 days. Bottle and/or keg, and enjoy.
This was my second attempt at a clone of it, and while it is delicious, it is not exactly STier Harvest. But it is a good starting point to continue on and try more.
