Yam It Yourself: Yamma Jamma Homebrew Recipe Is Here!

As you may have heard (cover your ears if you haven’t), our Harvest Ale is hitting the hay in 2017. We know you’ll miss Yamma Jamma, and we will too - so we’ve decided to give you a little something to remember it by. Our brewers have created a 5 Gallon All-Grain Batch homebrew recipe just for you. Find it below, or on the recipe page of our website, alongside Day Tripper and Midnight Ryder.

If you’re brewing Yamma Jamma - let us know! We’d love to pass along what we’ve learned about working with those crazy yams all these years. We’re so happy to finally share this recipe and welcome you to the yamily. Dang, we’re really gonna miss those puns. And one more thing - whether you’re a homebrewer or just a homedrinker, you’ll find $10 Yamma Jamma growler fills all November long at Indeed to send off our sweet potato beer right. Pick some up for Thanksgiving, it’s way better than a casserole.
