two tun old ale

eric and i started talking about brewing an old ale a while ago. we knew we wanted it to be big, aiming for something like thomas hardy's ale rather than the traditional old ale guidelines. we thought this would be a good time to revive the two tun madness we used for the imperial stout last november. that was a doble-ish setup with one cooler and a bucket and 45# of grain. this time we decided to go bigger: two coolers and 60# of grain. we figured we could pull the second runnings for some kind of hoppy brown ale. a little reading and some tinkering with promash and it was set.

the parti-gyle recipe (grain bill only), dirty old brown ale, and the two tun old ale. the grain bill on the old+brown are mocked up to get the gravity right for calculating the hop utilizations and such.

grain for the batch. special b, honey malt, aromatic malt, and maris otter. tim loaned us his cooler tun, seen in the background.

the rest of the grain. total for the batch: 60.5 pounds, which should give us two 10 gallon batches.

the two tuns, waiting for action.

and two kegs, each with about half the grain bill. one is a standard 15.5gal, the other is only 13, so one has a wee bit more than the other.

eric, looking a little rough this morning!

and me, showing off my beer advocate toque.

strike water coming up to temp.

morning snacks. banana bread, chocolate chunk cookies, tangerines, and some deadly awesome savoury shortbread.

coffee, music, promash, and designing great beers. all the necessities for an early december morning brewing.

me again, a little dusty from the grain.

lunch! some pulled pork sandwiches, bbq fritos, and dogfish head olde school barleywine.

the two tuns, sparging away.

we collected into separate vessels so we could be sure we were sparging at the same rate and got the same amount from each tun.

that's 15 gallons of old ale at a gravity of 1.090. oh yeah, that's also before the 2 hour and 40 minute boil.

continuing to sparge. second runnings for the "brown" ale.

both batches on the burners. the old ale on the left boiling away, and the "brown" on the right. we steeped some chocolate malt to try and darken it up, but it didn't turn out very brown.

old ale starting to get angry.

both batches boiling now. the old ale started boiling 40min before the brown, and finished 40min after it.

both batches again. you can see my makeshift wind screen in the background and the scum skimming pot in front.

there's me reviewing one of the day's beers.

first hop addition on the "brown" getting angry...

a glass of something...i think this was the southern tier unearthly iipa. great stuff.

brew day beers: olde school, great lakes nosferatu, unearthly, and dogfish head world wide stout.

the "brown" happily fermenting. this one was kicking ass with almost zero lag time. 11gal at an OG of 1.057.

and the old ale starting to take off. 12gal at an OG of 1.102. didn't quite get the boil off we wanted, so we ended up with 12gal at 1.102 instead of more like 10.5-11gal at 1.115.

the "brown" got pretty angry, so i had to put it in some bins to keep the mess contained.

and the old ale now going full throttle.

in all, this was a good brew day. the huge grain bill and two 10gal batches via parti-gyle was pretty fun. several good brews sampled. the weather was even pretty cooperative, staying above freezing most of the day.

final gravity on brown was 1.017 for 69% attenuation and 5.28%abv. final gravity on the old ale was 1.034 for 64% attenuation and 8.96%abv.
