The Tasting

Arrived in: 500ML Bottle

Served in: Short Tulip

Mammoth celebrated their 20th Anniversary in 2015, and to commemorate their very special occasion, they brewed two different Belgian style ales. Bluesapalooza, a Brett ale, and this one, a Bourbon Barrel Aged Belgian Style Quadrupel Ale. Distribution for specialty Mammoth ales can be hit or miss in San Diego, so we grabbed a few bottles of this on our ski-cation a few weeks ago.

Having been barrel aged, we were not expecting this beer to be the poster child for clarity, but we were pleasantly surprised with its coloring. MBC 20th Anniversary poured an amber to dark caramel tone, with some cloudiness, but still just light enough to notice some lazy effervescence along the side of the glass.

Most barrel aged beers kill any chance of a lasting head almost instantly, but not in this case. This quad poured that trademark Belgian fluffy, yet somewhat uneven, stack of grainy foam that hung on for several minutes. After melting away, a thin sheet of froth remained.

As soon as the cap was popped off this beer, it let out an aromatic cloud of mustiness and oak. Once in the glass, the Belgian funk became more pronounced, but then the barrel aged character threw a booze soaked blanket over it. There were hints of orange, plum, grains, and damp must — but mostly hot fumes came on strong over the top of its earthiness.

In our first few sips, MBC 20th Anniversary was a little harsh, with a boozy orange peel flavor. Bourbon barrel aged beers have never been accused of being delicate, and this one didn’t really mesh too well to start. Much like the aroma, it boozed over the Belgian character.

But once the ale warmed up, bourbony caramel blended so nicely with the Belgian ale base. Raisin, plum, and brown sugar emerged — and this was what we were looking for the whole time. Once the whiskey reduced itself to a level just enough to pleasantly remind us we were drinking a barrel aged beer, the ale tasted like bourbon raisins braised in brown sugar with caramel.

Thanks to its malty body, the mouthfeel to this beer was fantastic. There was a touch of sharpness, but then MBC 20th Anniversary totally mellowed out into a full bodied creaminess like an imperial stout. Just be sure to let yours acclimate.

Final Score: 3.5/5

3.5 Stars

We are so glad we got to try MBC 20th Anniversary ale, because in our book, a bourbon barrel aged Belgian quadrupel ale is not the most common of beers! Mammoth’s special ale delivered a very unique combination of flavors that co-existed more harmoniously with some room temperature behind them.
