One of the my favorite double IPAs. The belgian yeast strain is a great twist on this classic.

Very well balanced for such a high abv beer.

Sourced a bottle in Denver, November, 2014.

App: Pours an almost orange-gold color, with minimal head that fades quickly. Opaque, with little effervescence.

Sm: Grapefruit, lemon thyme, followed by sweet tropical flavors like papaya.

Taste: Immediate sweetness dissolves into sticky, floral hops notes. Hops are balanced but definitely less forward than would be expected in a traditional double IPA. The resulting warmth from the relatively high alcohol (9.0%) is nicely balanced by tart, citrusy notes that could be the result of the Belgian yeast? It's almost IPA cross-bred with a saison - a great beer for a warm fall day.

An interesting beer when you're not sure you're ready for a palate-wrecking double IPA, but you want something that has floral hop notes to it. Would match well with Korean or Indian food (though I'd steer away from truly spicy stuff, given the ABV).

22oz bottle obtained in Nederland Co.

Pours hazy gold with plenty of dense, whipped head of white. A partial skim coat sustains throughout the glass with plenty of torn lacework.

Aromatics lead off with candied citrus fruit and pine. Apples, cloves and light bubblegum follow through. Orangey with pine-studded apples.

Medium bodied with a sticky, tacky mouthfeel.

Lush, sugar-dusted fruit starts the palate. Clove-spiked apples and some sweet malt follow through.

Finishes with lingering sappy fruit, bitterness to balance, and a mild warmth.

Very nice, but a bit on the sweet side. Dry it up and we have a fantastic beer.

River North Brewery Hoppenberg Uncertainty Principle Belgian-style Double India Pale Ale: That is a whopper of a name, and given I was a physics major I like the inside play on words. But how about the beer? The Belgian style IPA mash up is a tricky style, and I have had few the really come out well. River North's Uncertianty Principle may not fit the style perfectly, but it is a luscious beer not to be missed. All aspects of this brew are outstanding. A must try...

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.

On tap at the brewery served in a taster glass. Bright yellow-orange, filmy head. Aroma is esters and floral hops. Flavor is floral hops that slide into a soapy flavor accompanied by the belgian yeast spiciness. Overall I thought this was just ok though it did mask the alcohol well.

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.

Cloudy orange amber pour into a globe glass nets a rising head of two fingers. Retention is excellent and leaves attractive lacing on the glass.

Intense aroma of hops, booze and Belgian character. Wafting coriander, dried ginger and lemon zest followed by fruity peach, grapefruit and lemongrass. Alcohol aroma is less intense but present.

An explosion of Belgian character, coriander, clove, lemongrass and powdery yeast that blends with a tight pale malt graininess. Hop flavor is limited to a lemon citrus and grassy blast but bold bitterness matches well with the drying Belgian spices and yeast. Alcohol to finish.

High, crisp carbonation keeps this brew on its feet. Body is substantial and appropriate. Dries well though I wish the alcohol could be kept more in check.

Powerful Belgian IPA on all fronts, the spices, yeast and booze are really too much for the hops and malt in this beer. Lots of flavor, fairly complex and I can easily see why it would have a favorable rating. Just not my thing, needs some balance, subtlety and to let the hops shine.

Wet grass and tart lemon aroma wafts up from a semi-cloudy, golden yellow body. A thick, creamy white head hovers above the body; creamy and sticky. Bitterness headbutts you with the first sip, followed with a bready, yeasty malt character and backed up with a noticeable boozy character; peppery. A slick, slippery feel across the tongue, coupled with a tingle of tiny carbonation bubbles; crisp and dry finish.

An intense IPA with lots of bite. This one should satisfy those looking for big booze and big hop character.

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.

Excellent Belgian yeasty smell, tasting notes of sweet caramel, sugar, mealy bread with delicious subway-esque bakery yeasty with a long tapering finish and light spicy floral notes. For a 130 IBU it is phenomenally easy drinking. Bravo. Light, clear, orange look.

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

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

Great clarity. Awesome three-finger white (with slight green tinted head), brew is amber colored with lots of red and orange. yum.

Boom goes Belgium! BUT, not overly Belgian. Banana, spice, pineapple, mango, Pepper, cloves, unique.

Dry, awsome wet front with an incredibly dry and bitter aftertaste. Belgian yeast leads to weat coast dry-bitterness. Peppery, mango, red apple, bready, papery dryness, leather, and tobacco flavors and feel.

A great Belgian IPA which packs a nice punch @ 9%.. Definitely to be shared, as stated on the label. Well done River North, keep em' coming.. Highly recommended and VERY unique.

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.

130IBUs?

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.
