My adventure in brewing my first lager after all these years got off to a great start. The homebrew store I ordered from, Austin Homebrew Supply sent along Chocolate Malt instead of Carafa II for my Vienna Lager. I didn’t notice right away and after a few weeks when I got ready to brew I realized what I had and had to punt. With my Mexican Lager Yeast finishing up it’s 36th hour on the stir-plate I was all it.
Mexican Lager Yeast Taking Off
I went ahead and quickly reformulated my recipe on the fly subbing in a little chocolate malt and a touch of roasted barley for the carafa II knowing it wouldn’t be the same. I didn’t realize at the time that my recipe became nearly identical to a Schwarzbier recipe in ‘Brewing Classic Styles‘ by Jamil Zainasheff & John Palmer. So, I am not nearly as disappointed as I originally was when I first noticed and scrambled to pull up ‘BrewMate‘ recipe calculator and put this together.
I also had some challenges with my grain bag (doing this brew in the bag method of course) being a little too fine. My splendid wife sewed up a grain bag for me with my custom dimensions but when she went to buy the voile she was convinced by a lady at the unnamed fabric store that ‘all the brewers like to use muslin’ for grain bags. Not true at all. The muslin material when pulled out of the pot at 150F retained the water and it took at least 5 minutes for a lot of it to drain… not all of it, a lot of it.
Well, other than that it was a good brew day. I brewed with a co-worker who made a 5 gallon batch of an IPA and because I also forgot my propane and burner, we had to split up our time on his burner… I was on quite a streak.

Austin Homebrew sent chocolatee instead of Carafa II, so sub 1oz roasted barley for color and 1.6oz chocolate for the 2 oz carafa. This was going to be a Vienna Lager but the chocolate & roast barley make it a Schwarzbier.
