Used Sean Paxton's clone recipe.
Well we did this beast last night. Here are a few pics:

Mash Schedule: Abbey Mash Profile


Step Time Name Description Step Temp
15 min Acid Rest Add 46.20 qt of water at 99.6 F 95.0 F
15 min Protein Rest Decoct 13.04 qt of mash and boil it 122.0 F
15 min Gluten Rest Decoct 8.16 qt of mash and boil it 135.0 F
60 min Beta Sacrification Decoct 10.28 qt of mash and boil it 149.0 F
15 min Mashout Decoct 14.35 qt of mash and boil it 165.0 F


Notes:

In a bowl, mixed together 3 Oz. Amarillo, 3 Oz. Warrior, 3 Oz. Simcoe and blended together. Made 40 Dixie cups with 6.3 grams in each cup. Added 1 cup every 3 minutes for all of 120 minute boil.

Divided Dextrose into 28 individual 12 oz ziplock bags. After transfer to conical, started adding the second day, twice daily (12 oz in the morning and 12 oz in late afternoon) for 14 days. I had a 1 gallon pitcher and whisk sitting in a bucket of StarSan. Would dump 2 quarts from the conical and add 12 oz of Dextrose, then pour back into the conical. Towards the end, would see how fermentation was doing before adding. If fermentation slowed, re-think before you add more sugar as once added the final beer may be sweet.

1/2 gallon of wort was added to the high gravity yeast to make a starter. Second yeast was added on day 5 of fermentation.

Oxygen was added once daily for 4 days. 30 seconds @ 1200 psi with 0.2 micron SS Stone.

Dry hopping: Added 2 oz. Amarillo, 2 oz. Warrior and 2 oz. Simcoe to a bowl and blend. 28 ziplock backs were filled with 6 grams of hops each. 1 bag was added with each evening addition of dextrose and continued for a total of 28 additions or 4 weeks.

Fermentation was on the cold side, roughly 66-70 degrees. Lots of heat from the yeast.

OF ended at 1.050. Let sit for a few days on yeast to help finish fermentation. Stopped adding sugar on day 13. Total dextrose added as 21.5 pounds. Re-calculated OG was 1.200.

Bottled in 6 oz champagne splits, no addional yeast or sugar added. No carbonation. Final % with high gravity hydrometer was 20.7% abv.

Beer has aged nicely and a wonderful treat for on a cold night or for a beer tasting event.

Awesome brewing! One question- the gadget that it looks like you are adding hops into with the big hose clamp- can you explain?


thanks,
Gary

Looks like a hop bag hanger. Syrafoam cup thingy is PVC pipe.

Thats a piece of PVC with a big mesh bag clamped on it so we can add the pellet hops in and not have to use 40 bags. It basically sits on the kettle and hangs down to the bottom. The Warrior was in pellet form and the Amarillo and Simcoe were all whole leaf. The pellets dont play very well with the hop stopper, we usually re circ and the end of the boil and they compact on the hop stopper. The whole leaf does fine so we let them go in loose.

Three weeks ago brewed using the same recipe as starting point. I worried about the dissolution of the periodic sugar additions, so made saturated sucrose of defined concentration (100 g/130 g H2O), then did the twice daily additions with that solution (boiled for 5 minutes only to render sterile, and cannot support bacterial growth because of osmotic pressure). Using WY4347 Eau du Vie & DV10 sparkling wine yeasts to complete fermentation, and slowing over the past 2 days @ ~20% ABV estimated. Neat experiment. Tastes clean & crisp from the fermenter.

Very nice... you are gonna have to keep us informed on this one. I'm really curious as to how it turns out.
