Yam-Tastic Oil Change Porter

Over the winter holiday, I discovered that yams have a particular sweetness that I really felt must be included into a beer somehow. I started looking for yam ale recipes, but none gripped me. Then I stumbled upon a porter recipe for pumpkin, and simply decided to substitute yams for pumpkin and adjusted the batch for my experience and what grains were available to me.

My recipe:

5 gallon partial-mash

First Brewed December 14, 2014; Bottled January 10, 2015

At 60 minutes, add extracts and 1 oz Fuggles hops
At 30 minutes, add 0.5 oz Kent Golding hops
At 15 minutes, add 1 tsp Irish Moss
At 10 minutes, add 0.5 oz Kent Golding hops.

Completed, this porter is quite yummy, with a smoky flavor. Unfortunately, you can’t really taste the yams.
