Bottle shared by Eric that foamed over upon opening, thanks for sharing! Big tart cherry juice on the nose and in the flavor with just a hint of earthy light funkiness. Its a tasty beverage but I was honestly hoping for a bit more funk of tart or something,

Poured from a 750mL bottle into an Alchemist Arome glass. Purchased at the brewery this past weekend. Paired with Alchemist cheese washed in Petit Mutant beer.

Pour a deep maroon body with a pink fizzy head that reduces quickly to leave little lacing and no retention.

Aromas are heavy cherry, lots of berries, that's pretty much all I get here but it's fantastic. Definitely going to be sour by the nose.

On the tongue is a significant tartness and a TON of cherries, so much cherry, I love it. Funky yeast comes through on the follow through, finishing dry. Mouthfeel is medium light with high carbonation, very refreshing and easy to drink.

Overall a very well done beer. Tons of cherry and balanced acidity. Would be great in a barrel to add some depth and complexity.

2014 can, shared with another BA. Not a lot tartness present anymore, but some good cherry overtones and feel. Very fortunate to try this, I enjoyed it more than the dude I shared with, considering he remembered how it tasted "fresh". To me, after a year and a half, it was a lightly tart cherry beer with some brett behind it.

2015 can opened in Oct 2015

A – Whoa. Yeah, that is exactly what I want a cherry ale to look like. Bright cranberry and plum body. Pink head pours 2 fingers high before settling quickly back into the glass.

S – Deliciously dry nose with cherry pie, Jello, hay, and a touch of mint.

T – Cherry cobber, cherry pits, tart sourdough, and dusty barn notes.

M – Dry, medium-light body. Low carbonation.

O – More fruit ale than sour, but still really nice for what it is.

Sour, sweet, and citrus. A limited release that I received from a party they had for focal banger and this. I wish you could get it year round, or even seasonally, but I have yet to see it since. If someone has it.... TRADE FOR IT

The beer pours red with a fizzy, light pink head. The bubbles dissipate quickly. The aroma is sweet and sour cherries with some cough medicine flavor to it. A little bit of dust, but I have to look for it. Light honey sweetness in the background. Taste follows the aroma with a bit less fruit and more dry dustiness. It’s not really funky. Medicinal finish. Medium body. Some tang at the end. Not great.

16 oz. can poured into a snifter.

Appearance - Clear red body. Lightly pink head.

Smell - Smells kinda bland. Musty cherry and some cough syrup. Yeasty, too.

Taste - Much better cherry flavor, but it is a bit medicinal. Light tartness. Grain. Like wheat.

Mouthfeel - Light. Well carbonated. A it abrasive.

Overall - Not really impressive. Artificial tasting.

Light fizzy head, bright rosy hazy color.

Nose sour fruity cherry. Nice mild acidic tangy, hint of funk.

Taste pretty sour at first, then mellow tart cherry, hint of funk, nice mild acidic, little tannin stem. Mild acidic sour flemmy finish, little bitterness and tannin lingering with tart cherry.

Pours a deep ruby red with a brief lived huge effervescent head. Straw and tart cherry on the nose - little else. The flavor is very fruit forward with just enough tartness to make this highly drinkable and refreshing. Finishes with just a bit of lingering tartness.

I purchased eight cans of this beer at an Alchemist release party and wound up giving six away to friends who could not attend the event. I honestly felt like a beer Robin Hood that week. Unfortunately, I have since felt the guilt of giving away such a disappointing beer.

Those who remember the old Alchemist brew pub recall what the locals describe to be an amazing sour beer. Those who have tried recent iterations of this beer will certainly disagree.

The beer looks great, smells like cherries, and drinks like cherry cough syrup without the high with no discernible sour notes, just an unappealing funk.

It is not Rubaeus bad, but similar. Definitely not worthy of the Alchemist label.

Can received in a trade with Mark, thanks man.

This one pours a ruddy red color, with not much in the way of head or lacing. Looks really nice anyway.

This one smells very strongly of earthy, slightly tart, and slightly sweet cherries, with some definite brett aspects as well.

The intertwining of the brett yeast and the cherries gives this a very unique flavor. The cherry flavor is super earthy when laid on top of the mildly funky brett flavor. It's almost a dirty flavor. There's no sourness, and a mild amount of tartness that seems to be more derived from the cherries themselves than the yeast. The cherry flavor is full and rich, and really nice.

This is medium bodied, with a slightly creamy, but mostly juicy mouthfeel, with a moderate level of carbonation.

A really interesting beer, and nice to try something that isn't an IPA from the Alchemist.

The aroma is earthy, almost "muddy," but of red cherries.

The falvor follows with bright cherry flavor. The beer is clean throughout, although lacking in tart quality. It drinks towards a New Glarus with a dry finish and light carbonation.

Murky auburn with a fleeting head of airy bubbles that dwindles to a fine ring. Funky black cherry and cider aromas front-and-center, with some phenolics, a little earth, and grapes. Flavor follows suit with less funkiness...tart, juicy cherries for days. Dry medium body with some puckering acidity on the gums. Not super complex - pretty much just cherries everywhere and I'm okay with that. Thankfully, nothing like cough syrup to me. Thanks, Pat!

Reddish copper brown colored beer, evenly clouded with a white, small tight head. Aroma is loaded with cherries, slightly funky/brettified, lightly tart, sweet and woody, a touch of red grapes, musky, and something similar to raspberries. Taste is pleasantly tart, packed with cherry, reminiscent of tart cranberry juice, fermented fruit, and again some woody musk funkiness.

Very enjoyable beer. Tart funky cherry pie...

Part of the big share at Hunahpu’s Day 2014, poured into souvenir taster. Hazy red body with pink to white head that quickly fades. Some spots of lace left behind. Aroma is sour cherry, brett funk, earthy yeast, and cereal malt. Taste is bitter bretty earthiness, tart, sour, and medicinal cherries, and some malty sweetness. Light body, sticky texture, average carbonation, bitter medicinal brett finish, which is where this one fell apart for me.

Poured from a 16oz can into a Crooked Stave tulip.

Pours a murky amber with a pretty large one finger bubbly off-white head. Smell is sour cherry with that brett brux making the aroma that of a kriek. taste is musty cherry, leather, tobacco, and a little earthy grassyness. Feel is minimal tartness, medium-high carb, smooth, crisp and refreshing.

Overall this is not a sour ale by any means. There brett is there to really dry it out and bring that funky cherry to play. Still a very nice beer to sip on.

A: Bold, cloudy, ruby red. Very loud carbonation.

S: Musty brett funk, vinegar, and cherry jolly ranchers.

T: The tartness is there but overwhelmed by the artificial-tasting flavor of cherries and a bitter, cough syrup finish. Honestly, this tastes a lot like Robitussin.

M: Not sure if the slight syrupy sensation is there or an artifact of the cough syrup taste.

O: Happy to have tried it, more than happy to never have it again. Given that I traded something quite good for this, I might have to power through this one.

Thanks to AndrewK for sharing this one at his tasting.

Pours a hazy red with a foamy reddish-white head that settles to wisps of film on top of the beer. Tiny dots of lace form around the glass on the drink down. Smell is slightly sour with malt, earth, yeast, Brett, cherry, and fruit aromas. Taste is much the same with slightly sour earth, Brett, and cherry flavors on the finish. There is a mild amount of Brett bitterness on the palate with each sip. This beer has a good level of carbonation with a crisp mouthfeel. Overall, this is a pretty good beer but the Brett makes things more earthy and slightly medicinal over cherry aspects.

16 oz. (?) can obtained on trade (thanks, gmr75!), unknown brewing/bottling date but most recent vintage, poured into my The Bruery "Rue The Day" large snifter glass, drank 05/01/2014 over an hour.

A: 3/3 - red-maroon coloration, minimal clarity (cannot see through), tannish head pours fizzy and settles into a fine glass lacing persisting throughout the pour, small carbonation bubbles emerge off the bottom of the glass; moderate alcohol legs

S: 9/12 - the predominant aromas are sourish cherry and lactic acid; there is also some background Brett barnyard/tart character; no hop aroma

T: 15/20 - on the anterior tongue, there's a moderate sourness - sour cherries - that, I think, verges on medicinal; in the middle of the mouth, there's some flavors reminiscent of oak and tannins (which is odd because the beer is not barrel-aged); the alcohol is definitely well-hidden; finishes dry and inviting of subsequent sips

M: 4/5 - moderate bodied and appropriately carbonated (even effervescent) for an American wild ale; really nice dry, crisp finish that doesn't linger

O: 8/10 - a really solid sour fruit beer that I'm glad that I had the opportunity to try - other than some medicinal/Robitussin character, this was an enjoyable sour from a brewery that I (obviously) associate with hops; would I trade for it again? No; would I drink it again if offered? Absolutely

TOTAL = 39/50

Pours a deep, cranberry red with a lovely pinkish head, reminding me a little of FFaC going by appearance alone. Nose: cherries. Duh. Taste: cherries. Double duh. Little else need be said, to be honest; you do get a bit of brett as well, but this beer is dominated by cherries. I think Wisconsin Belgian Red may be the only more straightforward representation of the fruit in beer. Neither are enormously complex beers, but both are tremendously delicious.

Personally, I love this stuff. I think this beer would have been received better by the craft beer community if fewer people expected to pour a true sour into their glass. Nota bene: 100% Brett does not a sour make.

Can - sticky label, from the fridge into an oversize tulip.

Pour is gorgeous, not a word I would typically associate with beer. But this looks like cranberry juice with a thin layer of bubbles and a crispness around the edges.

Sour, dry nose.

Taste is underwhelming compared to the pour but in-line with the aroma; this is crisp, lightly sour with a good fruit presence.

Mouth is light, fizzy up front, almost nothing at the end. The carbonation is very faint, but there is enough to tickle your nose.

Really enjoyed this - missed it at the Brewpub so happy to have a second bite of the apple.

Poured from the can into my HF tulip...

A - Dark red color, decent head that leaves the glass fairly quickly. Pretty good lace retention

S - Huge cherry waft, some sour tartness, grape skin, Belgian yeast, grass

T - Cherry right up front mixed in with a decent amount of lemon acidity

M - Thin feel, high carbonation, a nice bite off the palate

O - I really enjoyed this. The cherries and sour mix well together. It's not quite puckering but gives you just enough. Great job Alchemist!

Poured from a 16oz can into a US tumbler pint glass.

A: The beer is a deep ruby red color, with a short pinkish-white head that fades slowly and leaves a thick lace on the glass.

S: The aroma contains cherries, wild Belgian yeast and light malts.

T: The taste starts out with a tart cherry flavor followed by an estery wild Belgian yeast flavor. The malt character is a bit heartier than most beers in the style. There’s a good balance for the style as well. The after-taste is slightly tart.

M: Crisp and a little smooth, medium body, medium carbonation, finish is dry but slightly sticky.

O: Tasty, goes down easily, not too filling, good kick, good representation of style, this is a solid beer to drink for a while if you want a sour beer that isn’t over-powering.

Pours a deep red with fizzy white head that dissipates quickly. Aroma has overwhelming brett funk that bring atty notes to the surface paired with cherry juice. Taste is moderately tart with a bit of fruity sweetness, and a heavy funk that seem to detract from the flavors the fruit is bringing. The finish is a bit syrupy with little lingering tartness. This definitely leans more to the wild side of things as opposed to the sour side. Mouthfeel is a bit heavy for style with low carbonation. Overall, I'm not too thrilled with this brew. The brett doesn't work with the fruit for me.

I'm kinda lovin this one.

A- Kriek red ale look with medium lacing.

S- Kriek but up the ante on fresh sour cheeries.

T- Less emphasis on sour than a 3F kriek, but more emphasis on fresh sour charries.

M- Medium body for the style with medium carb

O- A very well done domestic sour cherry ale.
