So yesterday we did our first rye.
Grain Bill 1,080 lbs un-malted rye and 120 lbs of distiller's barley totaling 1200 lbs of grain for a 600 gallon mash. All in all it went pretty well. Just one long F*ing day.
1. Add water to mash tun
2. Heat to 130 F, add rye
3. Bring to 185 F, and if using high-temperature alpha-amylase add now (Add Hitempase)
4. Hold (Hitempase rest) 60-90 minutes. pH should be 5.5-6.5
5. Cool down to glucoamylase temp 167° F and add Amylo 300 then add Barley at 150°F. Hold 60-90 min
6. Bioglucanase step. Cool to 140 F and add Bioglucanase. Rest for an additional 60 min if glucans are an issue)
7. Cool to ferment temp 80° pitch yeast at 90° maintain fermentation at 80°
Enzymes:
Hitempase Dose: 450-500 mL
Amylo 300 Dose: 500- 600 mL
Bioglucanase Dose: 60-80 mL
Yeast:
SafSpirit USW-6 500 gr – dose 2 bricks per 600 gallon batch
we ended up with 1.065 final gravity with a potential abv of 8.58% so all in all not bad.
Problems:
1. Clumping, played hell pumping to fermenters. we split the batch in to two 600 gallon fermenters to allow for foaming head space.
2. took all day, cooling is an issue for us as these damn vessels are so efficient. , Did not have much of a mess inside mash tun i think was a successful brew day with exception of clogging our hoses.
Question:
is there a better way that would take less time?
