Well, it’s almost that time of year again where the weather starts to cool down, the days start to get shorter, and the beer starts to shift back toward maltier and darker styles. With that comes the annual Oktoberfest and this year my homebrew club has decided to do a competition. We had to either brew a festbier or a marzen. I chose to go with an Oktoberfest festbier this year and came up with a recipe I hope turns out well. This was also the first time I have attempted a true step-mash to somewhat replicate a decoction mash without adding too much additional time to the brew day.

It’s been lagering for quite a while now and will be ready mid-September for our competition. Here’s hoping for good results!
