Pitched yeast from 2 starters, and 1 dry at 6:00pm  Very active fermentation by 8:30pm.  I put a blow off tube in right away.  I expect to see it pushing Kräusen by morning.

Made two 500 ML starters the day before.  Used a pack of Safale 05 in each.  They seemed to take off just fine, and produced a good yeast.  (This seemed evident by the fact that I had a good strong fermentation in the Ferminator just two hours later).

This was a huge grain bill for my equipment, but we did it anyway.  We ground it into two identical batches, of about 22.2 lbs per mash tun (we used my two 10 Gal water coolers).

Double Batch Sparge grains

• two mash tuns each with half grain bill
• 7 gallons mash water in each unit @ 155F
• mashed for 1 hour
• Collected 8 gallons of wort
• rested grains 30 minutes
• added 3.5  gallons to each for 2nd mash at 154
• 2nd  mash for 30 minutes
• Eat Pizza and watch football while mashing.Ravens beat the Oilers.
• Collected 7 more gallons of wort

Pre-boil gravity was 1.075

The brewhouse efficiency was calculated to be about 67%.

Boil kettle could not hold all wort, so we boiled 13 gallons in main kettle and 2 gallons in smaller kettle.  Then we merged them at 30 minutes

Boiled exactly 70 minutes, first hops at 60.  Then 2nd hop addition at 30 minutes, and final hops at flame out.

Added 2 whirlflock tablets and 3 tsp of yeast nutrient at 15 minutes.

We carried the full boil kettle (14 gallons) to the side of my house where we let it rest/settle for 20 minutes.  It was 25F outside, so it wasn't going to spoil.  We sanitized up our equipment, and drained the wort through my plate chiller and into my Ferminator.  Gravity is one hell of a pump!.

Pitched our yeast starters, plus one pack of dry Safale 05, and oxygenated the heck out of it.

Collected a sample from the kettle drain hose, and determined the OG to be 1.097.

Success.

I used a couple of hop bags for the first itme on this batch.  One bag held first and 2nd hop additions, and the other one for the final hop addition.  The bags really controlled the hop residue, but i am not sure how well the hops get used in the boil.  Tasting the wort after the boil suggested it worked ok.  Time will tell.
