The Tasting

Arrived in: 22oz. Bottle

Served in: Goblet

We needed to round out (and still do) our brown ale and/or porter review sections, and were searching for those styles at the beer store.

The large “Double Nut Brown” text and sketch of mountains on this bottle caught our eye, and the GABF winner sticker didn’t hurt its chances either. By title we assumed Double Nut Brown was a brown ale, but it was actually a porter.

Mammoth Brewing Company has been brewing award winning beer in the Eastern Sierra Nevadas since 1995. They pride themselves on being able to brew their beer with an ingredient most breweries don’t have at their disposal — fresh High Sierra water.

Double Nut Brown showed a small, one finger thick head when it was poured. The cap died off really quick, and left behind small pockets of foam. Soon there was nothing left but a pencil thin ring of bubbles around the edge of the goblet.

The ale was deep dark brown, but not so opaque you couldn’t see through it. It adapted to the sunlight somewhat at certain angles, where it lightened to mahogany color. Based on its dark tone, the mouthfeel of Double Nut Brown was on the thinner side, but it quickly overcame our palates with richness.

Double Nut Brown definitely lived up to its name, and started off nutty. From there, it took on mildly bitter chocolate with increased coffee roast in the finish.

This porter featured more chocolate aroma than flavor. But as the ale warmed it sweetened up, with more chocolate sweetness coming through, and less coffee bitterness.

Double Nut Brown was billed as a “a big brown porter”, and we would have to agree with that statement. It was a very smooth and robust ale, that packed deep flavor you would expect to find in an imperial porter.

Final Score: 4/5

4 Stars

We were glad we gave Mammoth Double Nut Brown a shot. It was a good quality porter with plenty of nutty, chocolate, and roasty flavor. This beer is worth recommending, and we would absolutely drink it again.
