I'm really glad this beer is back.

A gorgeous ruby color with a long lasting pinkish head.

A bit of funk and cherry in the aroma.

The cherries give this a tart yet satisfying taste with just enough funk. If sours are what you crave this will fit the bill. A nice amount of carbonation.

Very drinkable, abv very well masked.

notes from Vermont trip this past April...
Appears a crimson toned amber with a fizzy white head with rose highlights bubbling through. The cap slowly fades into a gentle floating film with a mild collar. Streaks of lacing are left around the glass.
Smell is of cherries, red wine, oak, vanilla, funk, and light earthiness.
Taste is of the mentioned aromas with a flavor that is of cherry and rhubarb with vanilla and wine breaking through into a sweet and mildly sour flavor.
Mouthfeel is medium bodied, very mildly tart, and evenly balanced with nice drinkability.

Amazing invigorating wild yeasty. Only 7 barrels-I would have done a growler. Peach colour with active little white head, lace in glass. Yeasty aroma. Smooth lambiclike, well balanced, long finish. Creaminess from wheat, fruit tartness from cherries. Would drink this all the time if local.

A creamy white head that lingers for a moment before settling, leaving some thin lacing with good strength down the sides of the goblet. A bright orange in color with hues of cranberry; slight chill haze.

A bright tartness in aroma: cranberry, cherry, and green apple. A touch of spice and even light oak that balances, yet doesn't take away from the primary sour aspect.

The light fruit flavors take center stage: pear, cherry, a splash of cranberry, and orange peel. The tartness is inviting and not overpowering in the least. There's a wood flavored character at mid-sip that is so minor that it's tough to put a handle on it. The aftertaste is a touch of candied sweetness along with the sour fruit quality.

Light bodied; prickly and crisp on the palate.

Rather refreshing; not my favorite style, but a brave concoction that turned out to be rather pleasant.

Enjoyed on tap this evening with dinner...cask every Friday and this is what they offer up in a 12oz. tulip glass.
Arrived a bright cherry with a full finger of bright white head...very creamy, though disappears within a minute or so.
Not huge on aroma, but what you'd expect...cherries and some earthy yeast to balance it out.
The taste is simply incredible...not overly sour, but the wild yeast really adds to the complexity of the style. A tad dusty in mouthfeel at first, but mellows out to be a real refreshing brew...quite tart, but not a sipper as I was expecting. Went down way too easy.
No hint of alcohol whatsoever...perfect for the season.
So glad to get the chance to try this one...and on cask makes it that much more special for me.

Ruby red appearance with minil head with a bit of lacing.
Aroma consists of cherries and fruit juices and all those familiar scents that I associate with Brett.
Flavor is cherry forward but not overly tart,

Too easy

A wheat ale fermented with brettanomyces lambicus and 500 pounds of Montmorency cherries...[in my opinion, superior to the wild child - the cherries are hardly detectable at this point in the maturation...but they seem to lend something that the wild child couldn't... desire for another glass.]

Poured a great hazy orange, almost rosy, with a wonderful head and lacing. detected a sour cherry/fruit aroma in the nose...the taste! bubbly malt fruit sourness up front, doesn't linger. refreshing and mildly sweet at mid bitterness [10 ibus], all mouthfeel and a perfect balance of the brett. soft and bubbly with a mid to light body - could easily drink this beer all night long...and will return to enjoy again soon. a great tang that kept me wanting more...and more...

On-tap at The Alchemist in a small snifter.

Very clear and cherry red, with some bubbles moving through it. Big head leaves a bunch of lacing.

Smells of cherries, a bit tart, with underlying Brett funk.

Taste is less funky than the aroma but still complex. Cherries hit first, a bit sweet but not too sweet, and turn pretty tart in the middle. Taste finishes tart, with the Brett and all its associated barnyard flavors. The taste is tart but not barrel-aged-level sour at all.

Medium body leaves lingering cherry flavors on the tongue.

A good showcase of cherry flavors and Brett. I was hoping for something a bit more sour, but this was very enjoyable.

Poured out dark reddish with a thick white head. There's lots of fruit and sourness in the nose, cherry mostly, but also cranberry, and a bit of pear. There's nice balance, this is a great tasting beer. IT's a little too bubbly for me, chewy in a way. Might be better if I let it sit, but still very drinkable.

This is my second time coming back to the alchemist and i have been on a sour kick lately, so of course i was happy to see this style on tap.

The color was ruby red with a nice two finger pinkish head. The smell was cherries, lemon zest, little funk and slight oak.

Starts off sour and tart with a little sweetness coming from the cherries, then in the end this beer balances out beautifully with a nice nutty, slightly buttery finish.

This beer is excellent and very easy to drink. You can defiantly have a few of these without the tartness killing your mouth.

If you like sours this is a very good one balanced yet complex at the same time. Hope they keep this one back in there rotation.

Pours a beautiful cranberry color with a one-finger head into my glass. I'm in love with the color.

A slight funk greets the nose followed by apple and cherry aromas.

Tart with a good amount of funk. Cherry is the dominant flavor (as it should be) and rounds out the palate.

Mouthfeel is.slightly tart/acicdic with lingering cherry notes.

Very drinkable. Deceptive. A masterpiece.

look: 5 | smell: 4 | taste: 4.5 | feel: 4 | overall: 4.5

the menu stated 8%abv... sure its different with each batch.

pour is reddish pink with a slight off white head that is quite large. about 2 fingers if not more. nose of funk and grassy minerals with a citrus subtle earth tone of nothing but a ripe raspberry. palate is not sweet but with a tart and extremely mild bitter grit. like you're chewing on flower leaves. the mineral is not something that compromises the beer with a false carbonation feeling. not extremely dry for a sour but subtle pollen notes. great. had it with the prawns.

Off tap at the brewery this beer was a color like Ruby red grapefruit color with one finger of pinkish head. The retention was very good and the lacing impressive. The aroma was of must, berries, cherries, Bret yeast and wheat. The flavors were on-point for a wild ale, tart, tangy and complex. I tasted Bret yeast, strawberries, Mexican candy (artificial flavoring) and lots of sour cherries. For 7.9% this beer barely showed any heat and was very easy to drink. The mouthfeel was average, the body medium and carbonation medium.

On tap at the Blind Tiger for Vermont Beer & Cheese Night. Served in a tulip. Bright red appearance with minimal head and good lacing. Think the color of grapefruit or cara cara oranges. Apparently brewed with 3 strains of brett and 1000 lbs of cherries, and aged in pinot barrels.

Dangerously drinkable and balanced for a 7.8. Unquestionably has a brett kick, but doesn't burn nearly as much as I would expect for a sour, let alone one with this high ABV. Tastes of sour cherries and cotton candy with a champagne bite, a full tulip goes down way too easy, and so far my stomach doesn't hate me. Fantastic.

Appearance: A ruby red color and cloudy, a very thin head.

Aroma: Some sourness, cherries and a little alchohol.

Taste: This beer actually tastes like a cherry soda with a subtle but noticeable red wine flavor. Like they added some Pinot Noir into it. It's sort of like a red champagne, with cherry syrup in it.

Mouthfeel: Good carbonation and mouthfeel.

Drinkability: This has good drinkability for a sour.

Finally made it to The Alchemist, and glad i didnt wait any longer.
This arrives a beautiful ruby red with a one finger head. Lacing is left all over the glass once it depletes.
What a hell of a nose, with cherry, fruit punch (kind of kool-aid) ish, and just the right amount of tartness. Absolutely love it.
The flavor backs off slightly from what the nose gives you, (however still solid) and really lets the sourness shine. It lingers just enough to make its presence known, and begs you take another sip, let alone order another one. The cherries truly are wonderful here, and i think its the best expression of the fruit ive seen in beer. Absolutely stellar.

This batch was 8%, and I want to say it was like 2 IBUs?

A: Gorgeous red glow from the small snifter. Pink grapefruit like active head due to carbonation level. Most people at my table did a double take at the appearance, they didn't know beer could look this way.

S: Here's the Brett I was missing so much from the Whonky. No mistaking the Montmorency cherries in this one either. This one smells like its going to be sweet and fruity, but the funky yeast keeps coming back to remind you all is not as it seems. Skating along through it all is a slight bit of sherry vinegar. Upon some digging I pulled up a very minor amount of soapiness.

T: Instantly surprised by a metallic taste, very much reminding me of Monk's Cafe Flemish Red. Started off sweet and fruity but then turned acetic and funky from the yeast. There was some off flavor that I couldn't identify, it wasn't off putting, just out of place. For a second I thought it might be almost like a cherry cough drop, but that wasn't really it. After a few sips I noticed the finish was very tannic.

M: Nice juicy mouthfeel but still drying due to the tannic nature. Extremely drinkable with the 8% ABV well hidden.

O: Not as complex as I had hoped it was going to be given the description and my first smell, but a great beer for someone just getting into sours or not even yet into beer. Represented everything it should, if just not in the right amount. I got a sense it was very much like Cantillon Rose de Gambrinus in the sense that it starts off very sweet and fruity but would develop and sour-up nicely with time.

Popped in for dinner with chowdahead, hoping to find some Heady Topper or saison, but we were very happy to get to sample this instead.

Light ruby color with a pale white head. Smells of tart cherries, some funk, even a little citrus. The taste is superb: smooth cherry notes but not overly tart - it was easier on the palate than I expected. The Brett was noticeable but was balanced with the other flavors. I would say this is very Cantillon-esque, but it was less dry than their kriek, so I have to admit I liked this one a little more (not to say that I wouldn't jump at the chance to drink more Cantillon. Who wouldn't?). Drink Petit Mutant. An enjoyable beer with an enjoyable name.
