Brewing at Sanatar's - Hopfenweizen and a Double Mountain IRA clone


My club is manning a booth at Cal Expo for Sacramento Beer Week, so I set myself to the task of brewing a couple kegs-worth of good beer to represent our club. One batch is going to be a bigger, badder version of my Rose City Black IPA, and the other is a collaborative brew. My friend John (who I think is the club president), had a bunch of wheat malt lying around and I had a bunch of pilsner malt taking up space, so I figured we could brew a wheat beer - but with a twist. We're brewing a beer that meets the reinheitsgebot definition of a "Weizen" (meaning nothing but hops, water, malt, and yeast - with greater than 51% of the malt being wheat), but would drink like a hoppy American Pale Ale. We're calling this style "Hopfenweizen" which means "hoppy wheat beer" in German. There is a beer out in the midwest that I've never had called Gumballhead, which is said to be similar, but I have never had it, so I can only guess as to how this beer is going to taste.

We brewed it at John's because his garage is a much nicer place to brew than my tiny apartment balcony. In addition to the hopfenweizen, we brewed a "slightly-bigger-than-the-real-thing" clone of Double Mountain IRA, a beer I miss not being able to get since leaving Portland. There was a twist to this, too (in addition to making it bigger and hoppier) - I split the 12 gallon batch of the IRA into 2 fermenters and am fermenting one with WLP540 Belgian Abbey IV, a Belgian strain nearly identical to the one Double Mountain uses; and the other fermenter was going with ECY10 Old Newark Ale- an American yeast strain sourced from the now-defunct old Ballantine Brewery in Newark, NJ. The American one is fermenting in the mid-high 50's fahrenheit and the Belgian is fermenting in the mid-high 60's fahrenheit. This is the first time I have split a batch like this, and I am pretty excited to see how it will turn out.



The recipes are below. I will post tasting notes and pictures of the beers when they are done.
