#60: IPA (5 gallon - partial mash)

First brew day with friends yesterday.  "Big Brew" a week or so late.  They wanted to do an IPA, and we wanted to shoot for less than four hours, so a partial mash on the new equipment seemed in order.  Cut some corners by hop-bursting the bitter and also by partial mashing and thus adding cold water at the end to get to volume.  Wrapped up in about 2.5 hours.  Super-efficient brew day considering two of the three people had never brewed before.  Did some grilling early and ordered pizza late, and also consumed a lot of beer.  Good times... 

Another side note...  Used some of the Summit I ordered from Willamette Valley Hops.  Funny thing is that every time I order from them, I end up with twice as much as I ordered.  I had spec'd a 55IBU, with a 1.5oz addition of the Summit, but they wanted to go more bitter, so we went 2.0oz for a 100+ IBU.  These hops have been in the freezer for a while, so likely I won't get that much out of them (though they still smelled great)...  Probably gonna get something in the 80ish range, but no real way to judge that.

Missed the OG by a touch.  I found when I was cleaning the equipment that there was some of the LME coating the bottom of the pot.  I guess we didn't stir well enough.  RDWHAHB...  Still should be mighty tasty.

Also, got my lagering fridge working again (at least temporarily).  So I guess I didn't need to trade my lager yeast in after all...

  1. Bottled today... 47 bottles; 564 oz; 4.40 gallon haul. Was hoping to get 50 bottles, but didn't quite make it. Taste was fine... not as hoppy/bitter as I would have expected. Maybe the hops had lost more than I thought they had. RDWHAHB. It will make a nice pale if it's not as hoppy as intended.

    It was good to have a second set of hands for a 5 gallon bottling day. One of the collaborators came back for the bottling. Breezed through it with very little issue.
