Batch 60: Walrus porter

Brew date: August 5th, 2019
Bottle date: TBD

Walrus is my American-style porter, BJCP category 20A. My starting point for this recipe is a clone recipe I had come across for Founder’s porter, but I’ve also modified it quite a bit. I am targeting the mid-range for ABV but towards the upper range on IBU. As with all my beers, it will be bottle conditioned, which is not my preference in this case but I will work with what I’ve got.

I mashed all grains together, rather than cold steeping the dark grains. I will likely try cold steeping in future batches. I had planned to use Escarpment Labs’ Scottish ale yeast, but upon making a starter I found the yeast to not be viable any longer.

Brew Day Notes:

Brewed on the patio. Mashed in 12:45pm at 55C. Bumped up to 67C at 1:10. Reached that temp at 1:20. Raised to 75C at 2:30. Sparge started 2:45, finished 3:00. Boil start 3:45. Transfer took about 25 minutes. Pitch temp was 74F, but set the FTSs to 64F.

Tasting Notes:

[Aug 17, 2019] Primary pull. Down to 1.012, below target FG by a couple points. Aroma of chocolate and coffee. Nice full body, quite a dry finish with a touch of perhaps some higher alcohols. The warm fermentation is a little evident on the finish.
