Countdown IPA

20140202_103641

 

My method for doing brew in a bag batches.  The lid is usually on and I tend to the mash temp every 10-15 minutes.

In the quest to make an original house IPA recipe, I’ve been brewing 3 gallon Brew In A Bag recipes for experimentation purposes.  The last time I attempted this was on February 2nd and it was an interesting brew day…

I started off with about 5.5 gallons of water in my kettle.  I just kind of eyed this amount instead of measuring, which is part of what lead to my slightly low pre boil gravity.  By my calculations my final gravity would have ended up at about 1.058 based on a boil off rate of 1 gallon per hour.

Early on I decided that I would take a refractometer reading right before my 10 minute hop addition to see how my gravity was doing.  To my dismay, my estimates were correct.  The gravity was coming in a little low and we can’t have that!  In an effort to raise the FG a little, I added an additional 10 minutes to the boil prior to my 10 – 1 minute hop additions.  Fortunately I nailed the simple time/gravity math perfectly, the next reading after the extra 10 minutes of boiling showed that I was back on track for my calculated OG.

At this point I started my countdown hop additions.  This brew was based on hop bursting and whirlpool/hop stand additions to make up for the lack of bittering hop addition at the beginning of the boil.  I am hoping to come up with a house IPA recipe using the hops below since I have an excess of CTZ, Cascade, and Centennial.

This was also my first experience with WLP090, Super San Diego yeast.  I noticed that Scott over at Bertus Brewery has been using WLP090 as his house yeast for a while now and the thing is apparently a BEAST.  I can confirm that this yeast is indeed completely F’ing bonkers!  I didn’t make a starter this session due to the batch size and some time constraints.  My airlock started bubbling after about 5 hours and was very active within 12.  Primary fermentation seemed to be “done” within 2 days or so, and the beer dropped clear after about 3.  That is pretty insane for not creating a starter.  I also plan on attempting my first round of yeast washing with this yeast.  I brew allot of beers that call for California Ale Yeast and this seems like a killer replacement for it, plus yeast washing will save me quite a bit of money over the next few batches of beer.

I had originally planned on using CTZ as my bittering hop, but I had some warrior left over in the freezer and decided to use that instead to get rid of some of my old left over hops.  I’m just rambling at this point, so I’ll leave you with the recipe.  I will post a picture and some impressions of the finished beer in the next week or two.

Thanks!
