After doing some very preliminary research, I knew this was the first and only pint I needed to order here...and yes, you read that right: 130 ibus!; I think this is the highest claimed amount of IBUs I've ever drank in a beer; some folks in our party say the beer has a distinct anise flavor...I say it smells like heaven; the color is bright and solid amber; no head and light non-consistent lacing; the nose is like a grapefruit slap in the face; amazingly, this beer doesn't taste as boozy as 9%abv; I'm a huge fan of this beer...kudos for aggressive experimentation.

Bomber labeled as Hypothesis.

Seved cold into a goblet.

Hypothesis is a golden amber color with great clarity and thin short-lived head.

Aroma is sweet and slightly spicy but has surprisingly little hop aroma for a double IPA.

Flavor is much stronger and mor bitter than the aroma would suggest. A slightly sweet start to the sip leads to a big bitter hop bite towards the middle. It finishes a bit more dry but the hoppiness lingers on.

Mouthfeel is medium bodied and nicely carbonated.

Overall a solid effort from a River North. It has similar elements to its saison, probably the yeast, but is geared more for the hop head.

This is an extremely smooth ale. Seems to be much more on the Belgian side of things as opposed to the IPA side, as the hops are minimal in comparison to the sweet tones of the beer. Pretty thick body and flavor profile., but still quite pleasant to drink. Glad I had a chance to pick this one up.

double ipa, like this one a lot. pours clear golden with a slight amber hue and a great big white head with awesome lacing. smell is right on, lots og big fresh citrusy hops, so juicy in the nose you could wring it out. love the smell. impeccably fresh. flavor is not as intense as the nose, but delicious for sure. hoppy yet balanced by some interesting beklgian yeast and pale malts. a very very drinkable big ipa. mouthfeel works well, medium carbonation and medium body, this is good juice. ive heard they are going to bottle this, which should bring some recognition to this place. all of the river north beers are good.

Got a bottle at Mile High in early April.

For the high ABV and 130 IBUs, this drank smooth. The belgian yeast kept the hops toned down. The grassiness, grapefruit notes were relatively subdued. The high alcohol is well hidden so be wary if you take down a whole bomber solo.

The color is on the darker side of the IPA spectrum.

Shared with a few folks and it went down very quickly. Another solid newcomer to the Denver craft brew scene.

On tap at the brewery. According to the chalk board the beer has ~130 IBUs with ~9.0%ABV. Served with a 10oz pour the beer arrives a hazy golden color with a small 1/2 finger white head, some retention and lacing. The nose is malty with caramel tones. The hops are bright but not entirely dominant with hints of tangerine, peach, passion fruit, and grapefruit. The flavor starts and ends bitter. As malty as the nose lets on. Caramel malt and fruit flavor as described in the aroma. Finishes dry with a lingering malty citrus bitterness. Full bodied and well carbonated. Overall, not a bad brew at all. Not sure how many I could drink both due to the high abv and the high bitterness, though.
