Brewday & Tasting Notes: Inverted Fest (Marzen)

 A couple years ago I brewed a version of this award-winning recipe from Ian Anderson of the Boston Worts. I'll be damned if that was not one of the best beers I have ever made!

Now, I did to make a few adjustments based on the ingredients I had on hand.

Tasting Notes from my brew log: Might be the best lager I've ever made. The consensus is that my beer is better than Notch's Festbier.  Definitely more malt forward and less hoppy than Weinstephan Festbier. 

Overall super smooth, touch of sweetness, enough hop character to finish clean. If anything it could have used a little more body and breadyness. That could be corrected with better yield in brewhouse. 

I replaced the 20% Vienna Malt with 10% Munich Malt because that's what I had. The 5L Caramalt really gave the beer a subtle sweetness that I think put it over the top. 

One thing I love to do is play around with grists. To take the percentages and change the ingredients. In the Festbier Malt A was 85%, Malt B 10%, and Malt C was 5%. I wondered what would happen if Malt A was Munich instead of Pilsner Malt, Malt B was Pilsner instead of Munich, and Malt C was a different Caramel or Crystal Malt. This beer, I put that theory to the test!
