Recipe Type: All Grain
Yeast: W-34/70
Additional Yeast or Yeast Starter: repitch from slurry
Batch Size (Gallons): 6.25
Original Gravity: 1.085
Final Gravity: 1.024
IBU: 26.0
Boiling Time (Minutes): 90
Color: 24.2
Primary Fermentation (# of Days & Temp): 10 @ 47
Additional Fermentation: 10 weeks @ 32
Secondary Fermentation (# of Days & Temp): 7 @ 65
Tasting Notes: rich maltiness balanced by moderate bitterness

20 lb 4 oz Weyermann Munich
2 lb Weyermann Pilsner
1 lb Caramunich
8 oz Chocolate

2 oz Hersbrucker (3.5% AA) 90 minutes (FWH)
1 oz Tettnang (4.8% AA) 27 minutes

Hochkurz Double Decoction Mash
Maltose Rest 90 minutes @ 146
Dextrinization Rest 60 minutes @ 160
Mashout 15 minutes @ 170

Half of this batch was used to make an eisbock which was freeze distilled at 19 degrees. I ended up with 24 twelve ounce bottles of doppelbock and 18 of eisbock. The eisbock (named Otto I) is incredibly rich--reminds me of a port. Would be a fantastic dessert beer.

So, just to be clear, this is a 10-gallon batch that you split?

It sounds pretty delicious. Hopefully I'll get a chance to try some lagering after a few more batches, so I plan to bookmark this one and give it a shot.

No, it was a 6.25 gallon batch. Both the doppelbock itself and the Eisbock it fathered turned out very nicely. IMO the keys are using the correct proportion of Munich and taking the time/effort to decoct. I can't wait to make 10g of this again this fall! In the meantime I think I'll do a Maibock soon.

for a 6.5 gallon batch, I am calculating 1.099 OG... what is your efficiency?

Man... just saw this thread update... I seriously need a chest freezer.

What was your process for the freeze-distillation? Just pop the finished beer in the carboy in the freezer at 19°F and let it sit? If so, for how long?

According to my notes, 65.4%. Unusually low but I have noticed my beers with a lot of Munich have lower efficiency.

I racked half of my batch into a 2.5 gallon keg and the other half into a sanitized plastic pail with a tight-fitting lid. Purged with CO2 to minimize exposure to air, then into the freezer. I didn't take note of how long it was in there but not more than a few days.

Thanks. Man, I can't wait to make this... sounds soooo good!
