Blueberry Muffin IPA

Infected!

In my early days of brewing I found a post on Homebrewtalk about a Blueberry Oatmeal IPA and I tweaked the recipe a bit and brewed it. Everything was going well until I added fresh blueberries to the secondary and that’s when I got my first infection! Ever since I’ve always used frozen fruit and haven’t had any issues.

I rarely brew the exact same beer twice, but I often make tweaks and brew a similar recipe which brought up the Blueberry Muffin Ale. For this beer I used a base of 2 row, a bunch of oats (malted and flaked), a little Munich malt for some clean maltiness, and added some victory malt for that biscuity, toasy, bready component. I added a dash of maltodextrine for mouthfeel and mosaic hops later in the boil for aroma. I then added 3 lbs of blueberries for 7 days in the secondary and opted out (forgot) the dry hop. It was nice to revisit the idea of this beer and add what I felt the recipe needed. Check it out!
