Large shared bottle (thanks Dan).

Pours hazy reddish-brown with a decent head.

Funky and tart aroma with a faint hint of vinegar.

Flavor, as expected, much better than the aroma suggests. Tart , early puckering, with a multitude of soft, ripe fruit notes. Approaches 4.25.
Near medium body with medium carbonation.

Review from notes

Deep mahogany with garnet hues, quite clear, whitish head that left some bubbles on the glass. Lots of sour cherry, oak, plums, and a bit of sherry as well, indicating its oxidation content. Sweet and sour in the front, presenting a cornucopia of dark fruits and berries, which relays to a farmhouse funkiness and musty slabs of wood. Finishes tart and herbal. Very delicate and a pleasure to drink.

Got this as an extra in a great trade-- thanks my friend!

Reviewed from notes-- still trying to get caught up!

It's a coppery amber kind of ruby color. A whitish/off-white cap with some pink hues to it.
Smells like raspberries and sour cherries. Some oak, a touch of char.
(takes a break to watch a scene from "Walk Hard" that I had put on in the background)
Tart but sweet up front before the oaky vinegar comes around. All the while the notes of raspberries and cherries weave in and out of the foreground.
This is nice... probably not worth a great deal of hype, but nice nonetheless.
Medium body with good level ofbubbles.
I could drink this, but it is truly only better than average-- it certainly isn't setting any benchmark levels here.

Bottle thanks to Sean.

A - Orangish brown color with a little bit of a tan head that left a few random spots on the sides of the glass.

S - Little bit of funk, some tartness, some oak, vinegar, and a bit of sharp notes. It smells initially good but there is some astringency in there that is not all that great.

T - Cherries, tartness, vinegar, wood. It's a little too much on the vinegar sie for me, although it's not a bad Flanders Red. The harshness knocks it down a little bit.

M - A little astringent, medium bodied, with moderate carbonation.

O - This beer was okay, it had too much oak and astringency which made it a little hard to drink. Still, it was solid, wouldn't mind having it again.

Shared with Bendurgin on his birthday! Happy birthday Ben! Poured into a tulip. Nice dark reddish brown color. The head is small and spritzy.

The aroma is slightly metallic cherries.

The taste is slightly sour with just a touch of malt sweetness to go with it. The balance makes for really easy drinking, and the finish has a nice sour lemon zest kick.

The body is medium-light. The carbonation is relatively mellow.

I like this one. One of the better Ouse bruins or Flanders reds I have had.

Andy cracked this one open for my birthday. Thanks. Poured into a tulip. This is a dark red with a thin bubbly white head.

Lots of tart cherries in the aroma with oak rounding this out. Acidic vinegar and a little bit of sweetness finish this one out nicely. Sweeter on the pallet with a deep cherry flavor and notes of vanilla. Musty oak flavors and a slight tartness sum up the flavor. Vinegar is toned down on this quite a bit in the flavor with a more mellow tartness than what the aroma implies.

Light bodied with soft carbonation. One of the better examples of the style I've come across. I may even say my favorite to date.

Had some of what was left over from a Beer Dinner that Bullfrog did at Tap & Table back in August of 2010. The color was most definitely red without a who lot of head, kind of on the flatter side. The aroma smells quite a bit on the tart side. Stings the nostrils a little bit. The flavors were really sour to me. I knew that going into it but wow it was strong. Reminded me of some Kriek's that are out there with it's intense flavor. This beer is great for anyone who enjoys this style but for me it's just not my thing.

Pretty dark orange, head evaporates into a layer, lil bit of lacing.

Lots of oak, cherry, vanilla.

Aforementioned along with a light acidic citrus, raisin. Fairly sour for a Flanders Red Ale.

Nice light carbonation, as it warms up it dissappears.

Really liked this one, cherries and oak were balanced perfectly, along with a nice sour pang more reminiscent of an AWA.

The Jaspers has a ruby colored body and a solid white head. Good retention and lacing.

The aroma is pretty good, with notes of sourness, cherry, wood, vanilla, vinegar.

The flavor begins with a fairly acidic edge to it, that comes with quite a bit of sourness. A solid oak character comes out next, bringing a bit of vanilla with it, and also some noticeable cherry flavor. Next comes a moderate bite of red wine vinegar.

Fairly full body, but with a little bit higher carbonation than you might expect, and just a little bit of a puckering sensation.

I really like this one. Complex and sour without being overwhelming. The sourness and the wood flavors are nicely mixed. Nice example of a Flanders Red.

Bottle shared by Bmoyer0301 with him and stakem. Another fine Bullfrog sour...

A- A nice ruddy brown with a ruby hue. A nice and smooth stream of bubbles revealing a good amount of carb lead up to a thin white head. A great looking beer. Man The Bullfrog brews some art.

S- A sharp and pleasant lactic sourness right away greet me. As it warms up I continue to indulge in the lactic sourness and can pick up a sweet aroma of oak, vanilla bean and some earthy, must undertones. Very pleasing and subtle.

T- Wow! A great opening of mustiness, sharp acidity and lactic sourness. As it warms the finish is a quick snap of lactic sourness with heavy wood and vanilla hints. Very nice and tasty.

M- A great coating and syrupy feel are welcomed, but then you are hit by the puckering sour and tingly carb to push all the flavors around. A sharp acidity and a faint tartness are also provide a great depth and balance.

D- Yes sir! the acidity is sharp, but low and not overpowering. The always welcomed lactic sourness is divine and well integrated with the vanilla and oak undertones. The carb is just right and provides for a great experience.

Another solid offering from The Bullfrog. Keep them sours coming!

A: Deep ruby color with minimal white head.

S: Cherries and oak. Quite a bit of funk came in as it warmed up just a little. Oak came into play a little bit more as it warmed as well. The fruit comes across nice and clean.

T: Cherries and oak with just a touch of booze. The lacto gave it a nice complexity that set it apart. Quite nice.

M: The carbonation was a little less than I would have though. Syrupy.

D: A nice and really different take on a sour. Not a ton of funk or sourness but something in the middle with a ton of flavor. I have had a few of their beers now and this is one of the better ones.

Bottle 57/378. I've been sitting on this for awhile and decided to open it today-live review. Although I went to the release this is my first experience with this brew.

A- Body is a translucent medium red/mahogany hue. Fogginess is mild to moderate and slightly dynamic. Pours with a nice 1-2 finger creamy, slightly off white head which fades to and has great retention at 1/2 finger.

S- Nose is complex and colorful. Lots of soaked oak barrel, a hint of vanilla, vinegar, a slightly acidic tartness, sour apple, brett funk, a hint of cherry and dark fruit in the background. The nose is balanced and moderate to strong.

T- An acidic tartness is first to hit the palate along with impressions of cherry, brett funk and sour apple. This quickly turns as the soaked oak barrel shines through with a sweet vanilla like impression accompanying it-if you let it linger on the palate a fair amount of vinegar comes through and sticks around long after the swallow-if you don't let it stick around the vinegar goes virtually unnoticed. The barrel and vanilla flavors intensify for the finish as the acidic tartness and cherries come back around but are fairly mild-an overall mild balance between all these components lingers on the palate.

M- Light to medium prickly carbonation. A light to medium weight smooth and creamy body that isn't quite full.

D- This is a very interesting flanders red-where the nose is bright and exciting-the flavor is much softer-but has the same delicate complexity and balance. Its not heavy on tartness, vinegar, barrel, or fruit-its a nice balance of all of these. Its a great sipper.

Bottle # 284/378 big thanks to Bryan (wishuwerebeer) for cracking this open tonight.

Poured into a snifter this brew appears a clear dark amber color with a finger of copper tan head. Patchy lace clings to the glass. Constantly rising bubbles maintain the yellowish tanned film that resides across the top of this brew. Each swirl of the glass revives the cap of foam.

The aroma is malty sweet but in a not so normal malty sweet kind of way. It smells strikingly similar to cherry pits and some other fruity suggestions similar to a bit of pear/apple skins. Also included in the nose is some significant brett contribution smelling of wet leather. There is a solid about of woodsy character smelling not only oaky but also with a smooth mellow vanilla quality that rounds out the fruit character and really downplays the brett smell. Once warm, there is an increased amount of funky cheese smell along with a touch of alcohol. The smell of this beer is absolutely fantastic. There is so much to take in, I love it.

The taste of this brew has a sharp tartness from the brett that is a mixture of wet leather and tart cherries. There is some extra fruit flavor included tasting somewhat like apple skins. A flavor of toasty caramel grain comes through but overall maintains a dryness not typically associated with this sort of caramel malt flavor, but it really works. A cheesy funk flavor resides inside the mouth along with a bit of tart cherries. The dryness of this brew makes the tongue salivate and at times seems somewhat exaggerated by the dry woodsy flavor of the oak. In the background there is a smooth vanilla flavoring that does not quite come forward as bold as the nose would lead you to believe.

There is a minor puckering quality about this brew that encourages you to take another sip. It is medium bodied and lightly carbonated yet still has a prickly quality on the tongue. There is little to no indication of the alcohol in this brew despite it being enjoyed at a temperature which has to be pushing 60 degrees at this point. This brew leaves such a mix of flavors that at times seems just to linger with a woodsy oaked flavor that is fantastic and absolutely enjoyable if that sort of thing does it for you.

Bottle 48 of 378

Poured into Lost Abbey Tulip

Pours 1/2 finger of off-white head. Color is a cherry oak.

Aroma: Oak, cherries, sour funk, vanilla, spice, and a little brett.

Taste; Sour cherries, light funk, sourness is more dominate than the funk, oak, vanilla, horse blanket. Pretty solid. What I like about this beer is that it doesn't have any medicinal flavors.

Mouthfeel: Sour and refreshing. Clean sour. Medium bodied with a medium amount of carbonation. Ends clean.

Overall, a very solid sour. Very drinkable, nice sour. Well done. I am really happy with how this one turned out. Best part about this is how the brett didn't overpower the beer and make it medicinal. Very drinkable.

Bottle. Very, very excited to try this one. A rust copper mahogany color with not a whole lot of head. Strong sour cherry notes with some slight acetone notes. Some funk as well. Malty, sour and tart with some fruit type taste. No medicinal flavors at all. Subtle Brett flavors as well. Pretty well balanced. Some oak notes. More tart fruit and sour than anything else and in that sense it is really good. Light mouthfeel. A standout the night we did this tasting.

a huge thanks to the kind ne ba who sent this one down to me to enjoy. i decided to crack this one open this afternoon. served cold and into multiple tulips. this one was consumed on 09/12/2010.

the pour was nice, damn nice with a dark brown color with ruby highlights that come though as you hold them up to the light. nice tight head of light tan that kept up along the top throughout the session as it settled down.

aroma of tart cherries and rich sour notes that really come through as it warms up. huge farmhouse funk and vinegar notes that just would not quit. silky smooth feel and a rich warm tone let the flavor really just pop off the tongue with each sip. cherries, plums, sour and tart notes that bounce against a light woody note and rich malts. really complex, with a dark red wine finish that has a touch of light tannic notes.

overall a very solid sour and one of the best i have had from bullfrog in a very, very long time. i would have to recommend this one to anyone.

Bottle at an epic sour tasting. Pours dark cherry red with a wispy tan head. Nose is sour with black cherries, a bit of red wine vinegar, oak, and a touch of brett. Distinctively Bullfrog throughout and most akin to Beekeeper if I had to choose. A bit herbal. Really soft in the mouth, as another reviewer said "delightfully restrained" really does it justice. Oak, sour black cherries, currants. Very short and dry finish, which is a refreshing quality for this style. Only a very mild vinegar presence. Dry oak and wild brett round it out. I loved this one.

Review from notes. 750ml bottle poured into New Beligum tulip/snifter. Split with some of the Chicago crew at yet another random tasting.

A - Pours dark ruby red, off-white head, not much lacing at all and some bubbles here and there. Otherwise, just a base ruby red beer.

S - Cherries, oak, tart/sour notes.

T - Sour cherries, some oak, medium level of tartness.

M - Light body, light carbonation, dry finish.

D - Very solid brew we have here. I think I like this one just as much as Oude Tart and Red Poppy although the limited availability and what I'd have to give up for another bottle hurts this one.

Thanks, Nick. Hazy cherry red, nicely carbonated. A slim white head slowly settles to a thick collar. Strawberry and raspberry aroma, red wine, balsamic vinaigrette, a little brown sugar. Vinegary palate, ripe berries meet light brown sugar and oak. Light-bodied, tannic and vinous in the finish. Pretty damn good, Bullfrog is often underwhelming to me, but this is a very solid Flanders red ale.

Thank you Sean! Bottle 283/378 into a Lost Abbey glass...A medium brown, ruby notes. A light tan head with good carbonation, ok retention but poor lacing...The aroma is ok, tons of oak, really reminds me of the slight burnt and overused oak of consecreation or vagabond. Notes of oak, cherry, funk..The taste is a little harsh, the oak still reall comes through, really astringent. The cherries some through a little more here. This is an oud bruin not a flanders red. Super easy to drink.

A pretty decent attempt at an oud bruin. Appears to be have been aged too much in oak as it really comes through too much and too harsh. Maybe give it some more time?

Thanks to Sean for sharing this. Also had this before at hoppymeal's place, but I unfortunately can't remember who brought it. Served in a Cigar City snifter. Bottle #283/378.

A - Pours with a half-finger of tan foam that quickly dissipates to a thin ring and some light filmy haze. Only a few stray spots of lacing. The body is a transparent orange-brown.

S - Red wine vinegar, sour cherry, burnt wood, some funk, and a bit of plastic in there as well. This is a bit harsh and astringent - far more so than when I had it back in May. Not sure if it is bottle variation, or has just aged poorly.

T - Taste is more overripe cherries, lactic notes, red wine vinegar, and a bit of oaky vanilla and malt character. The taste is better than the smell as it isn't nearly as harsh.

M - A little bit of carbonation, but on the lower side. Pretty smooth medium body, and a slightly dry finish.

D - A solid Bullfrog offering, but I'd rather have Red Poppy.

Thanks to Steve (fbm115) for this one. Poured from a corked and caged 750ml bottle into a Cantillon Iris glass.

A: Pours a light brown thin film of a head that generates coarse bubbles around the rim of the glass. Beer is a semi-cloudy brownish-red. Lacing is thin and subtle with good retention.

S: Raspberries, cherry, oak, and ethanol. Very pure and aromatic. Fruity and quite rich overall.

T: Sweet at the outset. Dry, tart, and slightly acidic at the middle. Also, hints of cherry, raspberry, and a slight yeasty bitterness. Mildly vinegary and bready at the finish with a spicy aftertaste.

M: Medium bodied with a decent amount of carbonation. Oily and sticky in the mouth with a spicy accented finish. Aftertaste lingers.

D: A really tasty offering from Bullfrog and I'm glad I had the opportunity to try this one. Perhaps still a bit young and I'm sure it'll develop wonderfully through the next year or so. Can't wait to revisit this!!

Reviewed with speedwayjim, chrissy, stephy and Laura, served from a Kate spade snifter.

Appearance: red and brown brick and slightly cloudy. Spot lacing.

Smell: I get a sour and brown on the nose

Taste: opens with tart and sour brown malts throughout. The two profiles fluctuate in intensity as it approaches the finish. I get a tart finish and mild fruit.

Mouthfeel: moderate carbonation, light bodied and crisp

Drinkability: I would definitely have this again and recommend this to those seeking a sour brown ale with tons of malts.

A big thanks to Captinredbeard for hooking me up with a couple bottles...Corey, U da man! I have been lucky enough to try this on a few different occasions. This review is coming from notes from a sour tasting.

A- Pours dark brownish red in color. Two fingers of a off white head that dissipates rather quickly. Some sudsy lacing left behind. Lots of bubbles racing to the top.

A- A balsamic vinaigrette comes to mind with a tart cherry character. The oak is present along with mild suggestions of some funk. The cherries are really pretty big in the nose.

T- Starts out with a semi-sweet cherry profile that quickly turns tart, not very sour, but tart. The oak is definitely noticeable and there is a bit of lemon zest thrown into the mix. Not as much vinegar in the taste as was suggested in the nose. A really well balanced offering.

M- A bit acidic with a fairly high level of carbonation. Not quite a champagne level of carbonation, but we are getting close. A bit more body wouldn't have hurt this one, it was pretty light. The finish is tart with a dry oak feel to it.

D- A very drinkable brew! Quite tasty, I could have polished off multiple glasses. Very glad that I have two bottles, because I'm looking forward to seeing what a little time will do this one.

Thanks to ericandersnavy for sharing this bottle. Bottle 370 of 378.

The beer pours a reddish-amber color with a white head. The aroma is sour cherries with some caramel malt. The flavor is light funk, oak, tart cherries and vanilla. Medium mouthfeel and medium carbonation. A very good sour beer that lived up to the expectations I had.
