4.08/5  rDev +2.3%
look: 4.5 | smell: 4 | taste: 4 | feel: 4.5 | overall: 4

Poured from a growler into my La Fin du Monde tulip.

As advertised, this brew is a translucent hue of gold and apricot, with a sizable half-inch off-white head that leaves a ton of caked-on lacing. It's really a very pretty beer, and I almost don't want to drink it, but I must, for science! The nose is quite hoppy, with an undertone of grapefruit and grassy pine. Sweet caramelized malts appear after the initial barrage of hops, along with a very minimal tinge of booze on the back end.

A slightly sweetish note to start on the initial sip, which is quickly quenched by a big blast of hoppy bitterness. I've had bitterer brews before, but this is definitely living up to its touted description. Notes of pine resin and quite a bit of citrus accentuate the bitterness and provide a smooth contrast to the subdued, but substantial malt character. Booziness is detectable on the finish, but doesn't really detract from the drinkability, thanks in part to a lush, near-full-bodied mouthfeel. Carbonation is just-so, enough to support the tenuous spiciness.

After having had Altered Beast by the same brewery, Mach 10 was up against some admittedly stacked odds. And while it didn't exactly come close to matching its tastier brother, it is still a very, very good beer that hopheads and bitterbombers will enjoy very much.

3.5/5  rDev -12.3%
look: 3.5 | smell: 3.5 | taste: 3.5 | feel: 3.5 | overall: 3.5

A - Hazy amber, nice off white head, low carbonation, head fades to a covering quickly and leaves some lacing.

S - Light citrus and alcohol.

T - Boozy, alcohol up front and throughout. The citrus hops are there, but not a whole lot of hop flavor when compared to the bitterness and the alcohol. There is a bit of sweet caramel malt flavor in the middle, but finishes with alcohol.

M - Nice moderate body, that ends resinous and bitter. Some carbonation would help clean it up.

O - I love Bear Republic, I do not love this beer. Could really use some more hop aroma and flavor. I can forgive the carbonation because it was a growler...carbonation is also dependent on the server. Not their best beer or a great example of an American IIPA.

Served from growler into a Green Man snifter. Poured a deep red-orange with a minimal off-white head. Maintained phenomenal lacing throughout the glass. The aroma was comprised of sweet malt, citrus, citrus hop, passion fruit, wheat, and spices. The flavor was of sweet malt, pine, pine hop, citrus, fruit, spices, and subtle wheat. It had a medium feel on the palate with medium-high carbonation. Overall this was a decent brew. I honestly suggest you allow this one to warm up some as it was quite abrasive while cold. The pine aspect going on in this one was unpleasant at first, but grew on you after a few sips. Decently well balanced and complex, but just missed on what my palate enjoys in a Double IPA. Worth trying if you get the opportunity.

The beer pours a dark golden/amber color with a thick frothy off-white head that slowly fades to lacing. The aroma is good. It has a nice pale malt scent along with a wonderful citrus hop aroma. It's quite aromatic along with a bit of fruity esters. The taste is great! It has a balanced attack of hops and malts. It has mostly a pale malt flavor that's rich and a tad sweet along with an excellent hop flavor. It has a bold bitterness that meshes well with the malt character. The mouthfeel is fine. It is a full bodied beer with adequate carbonation. This is a good drinking beer. It's balanced and flavorful; another solid offering from Bear Republic.

growler from Village Beer Merchant. Cloudy golden with generous 3/8 inch of white head, and thick lace lines. Mild hop but bold malt aromas.Holding it together a spicey gummy Biere de Gard Big mouthfeel, extremely dangerous drinkable. Sugary sweet malt partners with citrus piney hops and makes the approaching Autumn...doable.

This beer poured a clear amber color and formed a foamy snow white head that left latticed lace as it subsided. A medium amount of carbonation is present. An aroma of hops, pine, citrus and a hint of caramel. The flavor was of hops, pine, orange and pepper. The body was medium light and the finish was bittersweet. The growler was from Barrel and Bottle and often that means you will find it on tap at Bodega.

Poured from a growler into a tulip.

Orange pour, light head, not too much lacing.

Sweet, hoppy nose. Loads of sweet malt and herbal, earthy hops. Was expecting some more citric bitterness than sweetness in the nose.

Flavor is sweet malt up front, then big piney, resinous hop flavor. Really, really hoppy without being overly bitter. Very good flavor.

Nice, thick body with a fairly low carbonation level. No hint of the ABV. Very easy drinker. Another good one from Bear Republic. Hard to decide if I liked this one better than Racer X.

Thanks to Deuane for sharing a growler on 12/14/09.

A - Dispensed from the growler as a hazy caramel-kissed orange liquid with a half-inch off-white head that reduced to a patchy film, but deposited thick, sticky lace all around the glass.

S - Wow! This beer smells like a Pink Floyd concert! This is some dank stuff, definitely very hemp-esque. Weed-like, leafy and earthy hops dominate the aroma. There is also a hint of sweet malt in the mix, but overall the dankness dominates.

T - This stuff is liquid marijuana, and easily one of the dankest beers I've had to date. The flavor is even more pot-like than the aroma. Some sweet, caramely malt is in there, but the flavor is just fat, leafy, earthy hops.

M - Medium bodied with an oily texture and a bit of alcohol heat on the palate. Carbonation is moderate at best. Finishes with a lingering hop bite on the tongue.

D - You put your weeed in there, man! This is definitely one skanky brew from Bear Republic, and should be enjoyed at around 4:20pm.

Editor's Note: I never smoked pot before, but I know what high people look like... I was at a Seals and Crofts concert.

From a growler into a pint glass. Big thanks to my good buddy Barscream for hooking several of us up with this while waiting in line during a recent beer release.

Pours a hazy copper, with a finger or so of egghshell-white foamy head. Retains stays rich, leaving back some equally robust lacing. The aroma is loaded with plenty of grapefruit character and more bitter citrus. It's also pretty floral and spicy, with some extra citric notes and malts providing the bulk of the sweetness. A bit of smoke appears from the malts as this warms, putting off a slight tang in the nose.

The taste is similar, with a LOT of bitter, juicy, grapefruit. The hop bitterness is more on the moderate side, with a good bit of spice that really shows itself towards the back of the profile. A toasted grainy sweetness sits underneath, giving off more smoky roasted notes while the finish is dry, spicy, and bitter with fruit. The mouthfeel is medium bodied, with a creamier carbonation up front that then gets more prickly towards the back of the swallow. Good drinkibility here for the size. I had no problem handling several samples of this.

Another well done IPA here from Bear Republic. While it certainly doesn't quite match up with a Racer 5 or X, it still brought it's own tasty game to the table, with namely lots of hoppy fruit and spice and a nice job of handling it's high ABV. Definitely worth a try if you see it on tap.

Growler received in trade with beernerd81. Thanks! Poured into a Bruery tulip.

A - A medium amber color...pretty clear. One finger of cream colored head. Head fades quickly to a thick, fairly even layer on the surface. Nice lacing on the glass.

S - Grassy and citrusy...a little bit of grapefruit. Not especially heavy in aromas - very subtle.

T - Heavily bitter. Bunch of hops...citrusy, grassy, pine. Alcohol is well hidden. This is very smooth...like a "DIPA Light"...

M - Medium bodied, carbonation is medium as well. Creamy mouth feel.

D - For a DIPA this is quite drinkable...maybe the alcohol is going to sneak up on me but it isn't apparent while drinking this....seems like a "session DIPA". Good DIPA, definitely better ones out there, but still quite good. Glad to have tried this one.

Served from a 64oz. growler, acquired in a trade from Wespatrick (thanks man!), into my Bruery snifter (11/20/09) at an appropriate temperature.

A: Pours a glowing golden orange with a two finger thick and creamy head. Very nice looking beer indeed.

S: Exceptional aroma of a rich and semi-sweet hop nectar with layers of orange marmalade, pine, grapefruit, and slightly sweet malt backbone. This is exactly what a west coast DIPA should smell like.

T: The aroma transfers into the taste as the palate is hit with a variety of hop flavors including; pine, grapefruit, orange, and tropical fruit surrounded by a layer of an orange marmalade nectar which intensified as it warms. A semi-sweet malt rounds out the flavor and allows for a nice balance while still maintaining a degree of bitterness in the finish.

M: A medium to full-bodied DIPA with a chewy yet slick character with a bitter finish that diminishes as the beer warms.

D: We will just say that that 64oz. growler is no more. This beer was exceptionally drinkable as the 8.7%abv. was expertly hidden. Any west coast DIPA fan with have no problem handling several of these.

Overall this beer was an excellent treat from Bear Republic and an outstanding DIPA. I just wish that Bear Republic bottled this or one of their other DIPAs. Highly Recommended.

Did not expect this beer to still be at the beer spot when I sauntered in...glad it was!
I am tasting this out of a Kolsch glass I picked up which works quite well for evaluating.
I was a bit careless in my first pour, alot of head (not usually a bad thing) the thick white head appeared so regal atop the copper, almost orange hued necter. Alittle hazy.
I can imagine the citrus wafting out of the glass and forming a come hither gesture to my nose like in an old looney tunes cartoon. Grapefruit and pine dominate.
The taste, oh the taste. like a grapefruit giving a healthy spank to my pallet. A descent balance but obviously the hops on showcase. A serious lingering of fruit rind almost in the bitterness. I think the IBU's are starting to strip away my stomach lining.
Mouthfeel is to be expected, not chewy per say but as thick as you would think an almost 9% IPA would be.
Drinkability...hard for me to define for such a robust IPA. It is what it should be but I wont be pounding these back after mowing, if ya know what I'm saying.

We're going to see fireworks. The kind where you sit on the hood of your car for hours and cuddle next to the one you love while sipping out of a red Solo cup what you pretend is sweet tea.
The sky is amber/orange as we reach our destination and begin setting up, a huge pillow of cloud cover that I hope dissipates at some point so we can see them... it's still lingering...
We finish, it gets dark, I cuddle up next to her and pop the top.
The aroma... tons of grapefruit peel, so much that it SMELLS bitter, and fresh cut pine in the back there, a bit of cheerio-like malt just coming in a little, but not enough that it detracts at all from the main event... It starts. The sky lights up different colors and our ears take a beating with every new explosion...
So I take a sip, while I glance away from the sky to look at the fire-sparkles reflected in her eyes (you are the most beautiful person in the world)...
Flavour of resin at first, pine sap, that quickly gives way to the note that you'd expect from gnawing on grapefruit peel, and the finish leaves exactly that, an immense bitterness that lingers and lingers.
The evening is brisk, I wrap my coat around us both and we alternate knowing glances and kisses on the cheek and forehead with gazing raptly at the explosions in the sky. It's full-bodied but not heavy, clean, dry and astringent, but with relatively low carbonation and that intensely dry, bitter finish that some learn to love and some are born in love with.

We are the latter.

A: An orange amber color and cloudy. Poured into the DFH signature glass with about a 1/4in head. Head stuck around for awhile and i am getting lacing with each sip.

S: Citrus, very pleasant.

T & MF: This is one delicious and smooth beer! I get the i nice citrusy hop flavor at the front, but absolutely none of the bitterness hits my until the end. I also get a some nice malty characters in the middle but they are brief. Medium to high carbonation.

D: Are you kidding me? Is this really 8.7%? This beer is extremely smooth and i have a feeling i could drink this whole growler tonight (and regret it). Amazing drinkability for 5% let alone 8.7%.

T: Taste is similar to the smell: Tons of hops, pine and citrus. A fairly bitter beer, but never repulsively so.

M: A highly carbonated beer with a dry finish. Medium-bodied.

D: A drinkable, clean beer. This is about as much a West Coast IPA as you can get.

Growler from Charleston Beer Exchange, poured into a chilled Duvel tulip.

A: As you expect from a dipa, bright translucent orange, short dense head.

S: Citrus, citrus, and more citrus

T: Quite nice, all the hops you could want but presented in a way that's not acerbic at all. Bitterness all creeps up on you in the back. Veeeery smooth stuff.

M: Again, smooth to the point of creamy. You know the hops are there, but it's not an oily feel whatsoever.

D: Deadly. Goes down way, way too smoothly for 8.7. This could get ugly.

Grabbed a growler from Charleston Beer Exchange yesterday-ultra fresh offering here.

App - Pours an amber/copper golden color with some decent head on a not-very-aggressive pour - lots of lacing

Smell - this is where its at. The hoppy fragrance on this brew is one of the best i've experienced on any DIPA, very very wonderful. Piny hops seems to nail it

Taste/MF - not too heavy on the palate, medium carbonation and tastes great like the smell. Lots of hops and piny notes, thats all i am picking up

Drinkability - I could probably clear a growler in an evening, I really enjoy this brew, the taste is amazing and the alcohol is just not in the taste, but I know it would catch up to even the most lush connoisseurs.

Overall - this is one of my favorite DIPAs to date and it's a shame its such a rare offering in my neck of the woods.

A: Poured a dark amber almost like apple cider with a 3 finger off-white head. Head retention is long and lacy.

S: The first noticeable fragrance is Grapefruit and other citrus fruits. I also smell Green apple skins and tangerine rind. It's a very nice clean smell, the hops smell very fresh.

T: Tart and slightly bitter, taste of citrus and citrus rinds. It tingles on the tongue but is very refreshing, almost like biting into a ripe granny smith apple and then chasing it with grapefruit juice. Nice and hoppy, would make for a good session beer.

M: The mouth feel is thin and warm. The alcohol is present but not overpowering. The carbonation is very nice, this beer is extremely smooth.

I think this beer is perfect for the transition from summer to fall, it matches the weather. It is nice on a warm day as well as a winter night. I definitely recommend this beer to anyone who loves citrus fruit and hops. GREAT BEER!

S - Scent of fresh pine, flowers, and an interesitng blend of hops. It is certainly different.

T - There is some initial sweetness, but it quickly changes to a medley of a bitter hoppy bite. This is a treat for true hop-heads.

M - Sticky feel that coates the tongue. Hoppy feel is intense, but did get a little tired.

O - Enjoyable DIPA that paired well with spicy food. Worth trying but is not quite on par with the noteworthy west coast examples of this style.

Had on tap at the ginger man in NYC- poured a slightly hazy golden orange color with a half finger white head; decent retention and a tiny bit of lacing.

Smell is very enticing- I smell piney hops and black tea (not unsimilar to sorachi ace). Nice bready malt sweetness with a bit of warming alcohol on the waY down. Excellent taste and perfectly balanced.

Surprisingly quaffable- good medium body with moderate carbonation. Buy if you find it!!

Had this on 3/2/12 at Gourmet Haus Staudt.

Never seen a DIPA that looks like this one - a hazy golden orange that looks thick like mango nectar and glows in the light. Looks beautiful topped with a finger of dense head and lively carbonation, good lacing.

Smells of concentrated citrus: orange marmalade, grapefruit rind, mango, melon, and some dank & floral notes. A bit of light breadiness and the ABV is hardly noticeable at all up front.

Hard to pinpoint but there is definitely something unique going on with the malt and hop bill. Lots of citrus like grapefruit, apricot and peaches mix with earthy and spicy English style hops and a notable amount of English-inspired malt - light bready and cracker notes with a bit of subdued sweetness.

Malt is even more evident in the mouth - sweet and creamy at first in a way that makes it more filling than a typical DIPA, but it still finishes fairly dry and with a lingering bitterness that you feel on the tongue, but not sticky at all. ABV becomes more evident after it warms but doesn't ever detract from the experience.

A really interesting DIPA that blends west coast and English character into a compelling experience. A big bitter beer that is utterly drinkable and refreshing, it took some effort to pace myself because I was enjoying it so much! Hope this makes it into a bottle one day soon.

Had on tap at The Gingerman, NYC:

A: Nice looking, dark IPA, modest head and lacing.

S/T: This is perhaps the booziest and maltiest of all the Bear Republic Imperial IPAs that I've had to date. It was almost like an American version of an English-style barleywine, given the huge presence of the West Coast hops.

M: Nice, creamy body. Relatively middle of the road.

O: Unlike anything I've ever had before from Bear Republic, but still a winner. It was not what I was expecting, given the the Racer X, Apex, and their others, but I think it serves a place in the BR library.

Had a mug at the Blue Tusk in Syracuse. Yes, it's hoppy and malty, but not hoppy enough for a DIPA. I guess I'd call it more of a blond American barleywine. The barley felt thick, even for a 9% beer, and wasn't particularly distinct. It was more of an overly-sweet caramel bread with a little toast. The hops don't stand out enough. The spicy citrus hops are balanced on par with a pale ale. Even if there's 100+ IBU, they're getting lost. I shouldn't get too down on this beer, it's tasty and something different for the style. I just want less sugar and more hops.

Cloudy amber with a orange body with a nice creamy white head. It leaves soapy like lacing.

Citrus, pine, floral, caramel and some breadiness with the aroma.

Pine, citrus, bread, sweet caramel, dough. Some alcohol at the very end.
