Imperial Stout | Beer Mentor

Today I brewed the M3. This is the sixth iteration of this one. My friend, Mike, and I brewed the original of this one back in 2018. This was on my old brew set up. His recipe was out of this world. We really enjoyed that beer … my only problem was I couldn’t find the recipe the next time I wanted to brew it! Haha.

I didn’t get around to brewing it in 2019 (I was still enjoying all the bottles from the previous batch). I used Maker’s Mark Bourbon in this first batch and all following batches. In that first one I used “small french oak” blocks I was given from a local supplier. I soaked the chips (but didn’t char them).

In 2020 and 2021, I crafted a recipe and bounced it off Mike. He said it sounded good–I used my French Oak Blocks again in 2020 but I made a mistake and bought pre-soaked (bourbon) chips for 2021. I found that I had the wrong kind of oxidation in that batch. They both were so big that they blew out the fermenter each time! I brewed these two batches on my old system. I think the 2021 batch was the last one before the new system arrived!

In 2022, I brewed it for the first time on the new system. This time, I made my own “oak staves.” I bought some American Oak, cut them to length, and then charred them on my grill. I soaked them in Maker’s Mark and then dropped them in to the secondary fermentation. I found that 3 days was just about the right length of time for that. I used those staves in 2023 and plan on using them again on this batch.

In 2022, I put 20 pounds of grain in my new brew system to make the Imperial Stout–it was too much! I was lucky to have some DME to use in the boil to boost up my gravity to make it an imperial stout. Last year and this year, I used around 18 pounds of grain (still too much) and added 3 pounds of Traditional Dark DME.
