Bourbon barrel-aged beers have been a hugely popular style ever since their inception in the early 0s by American craft brewers. By starting with a stronger-than-average robust porter, then infusing it with Bourbon-soaked oak (we recommend Maker Mark), the end result is quite possibly the best beer ever. Youl have to supply your own bourbon - save a little to sip on brew day to really capture the spirit. The intense aroma and flavor of toasted American oak and the sweet graininess of good bourbon meld with the bittersweet roastiness of porter to make for a very characterful beer. Recommended: 2-stage fermentation and yeast starter.
