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.

From BeerAdvocate magazine Issue #68 (Spetember 2012):

LOOK: Brilliant golden hue, killer froth

SMELL: Fresh herbs, tropical fruit, exotic spice, yeast, biscuity, dried grass, fume of alcohol, spicy

TASTE: Gentle smoothness, creamy, noticeable bitter, fresh black tea, grass, passion fruit, some spice, mild alcohol, hint of spice, walnuts, yeast, exceptionally long drawn out hoppiness, dry finish

A crazy mashup of styles results in brewers wanting to tackle it, River North nails what it is supposed to be. Belgian character first and foremost but bitterness nails it without ever letting go of what they yeast did. Very mellow alcohol for its size, any true hop head shouldn’t be afraid to climb this IBU ladened mountain.

STYLE: Belgian IPA
ABV: 9.0%

Pours a clear amber with a brownish tinge. Thin but long-lasting cap of foam. Nicely tingly in the mouth. A sweet aroma with something like geraniums.

An intriguing mix of flavors. The surprisingly strong clove flavor is the least pleasant of them. Better is the touch of cedar and mango nectar.

The yeasty dryness comes through midway. Bitterish finish, though less bitter than some of these Belgian hybrids I've been trying lately. Minty chewing gum plus a lot of pepper and pencil shavings. Orange with some orange peel. Still sweet in spite of the yeasty taste.

Quite sippable and you forget it's as strong as a summer white wine. From the 22 oz bottle purchased at Wilbur's Total Beverage in Fort Collins.

Well, the name is a mouthfull, and so is the beer.

Pours a nice solid golden color, nice billowing head. Some rocks. Lacing is great

Hops and yeast dominate the nose. White pepper, coriander and clove. Followed closely and powerfully by the hops. Citrus and tropical.

One thing I don't really love about B-IPAs is the emphasis on the B. This one does not fit that complaint. The Belgian flavors/spices (coriander, clove, bubblegum and white pepper) are there and provide a good flavor profile The soft biscuit and hops are what makes this beer really good. Yes, it's hoppy, buth combo of Belgian and American flavors is great.

Nice feel on it. Bitey, but not boozey. A really good beer

22oz into a pint

A - Pours a deep opaque orange color. Pearly white head that doesn't really build, just sits there as a film.

S - Very strong citrus notes, seemingly combining a floral hop character and what I think is the belgian yeast coming through. A little phenols are there.

T - Starts off smooth and sweet, going with pilsner and piles of 2row malts. Mid-stream the yeast takes over - the esters and white peppers rule the day. There are some citrus hops as well, a nice compliment. Finishes with a bit of sweetness and an increasing white pepper base.

M - Thick and creamy, carbonation is strong but just not enough to convince me its balanced or too in line with the nature of other belgians. alcohol warmth grows strong as the beer goes along.

O/D - A very solid belgian IPA. Hits all the main points for this non-traiditional style. A little bit boozy. A bit hefty and filling. The most notable flavors are just a little too muddled to consider this my favoriate BIPA, but its sure up there. I"ll have to try more beers from this brewery.

22 oz bottle. Pours hazy golden orange with a medium meringue white head that retains well and laces the glass.

The aroma is some fruit, funky earthy yeast, and some light metallic hops.

The flavor is sweet sugary bready malts with some tropical fruits and earthy yeast and a good sized bitterness in the finish. The mouthfeel is medium to full bodied with smooth carbonation.

Overall, a pretty good Belgian IPA. Not my favorite style but this has decent balance of funk, fruit and bitterness.

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.

Look: hop hazed yellow with orange hues
smell: Belgian esters dominate hop aroma.
taste: bubblegum, belgian earth, mild hop resin/dankness, touch of citrus, heat
Mouthfeel: classic belgian lightness, with a touch of hop body
Overall: solid Belgian dipa, would have preferred the hops to have more of a presence. Beer felt dominated by Belgian yeast. Also alcohol heat could be toned down

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.
