Notes: A light bodied, tart and refreshing sour blonde ale re-fermented in French oak barrels and aged on plenty of Wisconsin cranberries. Central Wisconsin is cranberry country, so it was easy to fall in love with the idea of aging our insanely tart sour ale on this beloved super fruit. We used two pounds of cranberries per gallon for maximum pucker factor. This is what taking chances is all about...going all out and ending up with something this wonderful.

look: 4.25 | smell: 4.5 | taste: 4.5 | feel: 4.5 | overall: 4.5
Poured from 750 mL bottle into tulip.
A: Pours a clear orange-amber hue with high carbonation producing a 2-3 inch fizzy, bubbly white head that fairly quickly settles to a thin skim that continues to be fueled by the active carbonation jets. No lacing.
S: Nose-smacking sour funk, tart cranberries, dry earthy minerals (almost chalky), tart lemon citrus, and a hint of oak tannins.
T: Sour funk (much more restrained here than in the aroma), immediately followed by tart cranberries and lemon. Underneath lies notes of oaky wood, vanilla, red berries, and a hint of cinnamon.
M: Light body. Sour and tart with a touch of fruit sweetness. Strongly sour on the nose with much better balance in the taste. Lingers and matures nicely on the palate too.
D: Refreshing and complex...always a nice combination! Would pair very nicely with a triple cream cheese. Seek it out!

Thanks to dujayhawk for sending this one! Reviewed from notes. Poured from a 750 mL bottle into an El Catador teku glass.

A: Pours a reddish, goldfish pink. A good amount of visible carbonation and moderate haziness. Forms a finger's worth of very light pink head that fails before I sit back down.

S: Tart up front – lactic and funky and feet. Tart cranberries and lemony citric acid. Light cracker malts in the background, but the sour flavors are certainly running the show here.

T: Tart cranberries. Lactic, funky, citric and acidic. Cracker malts still lurk in the background. Lactobacillus funk with feet and cheese in moderation. Lemony citric acid as well. Dry cranberries and underripe raspberries with lingering tartness in the hang – but not overly acidic. There's definitely some tart tang with a cranberry juice burn.

M: Light body, good carbonation sensation, and no alcohol to speak of.

O: A nice tart cranberry beer. This strikes an enjoyable balance between tart and acid and fruit and dryness and funk. Maybe not the fruitiness and depth of funk that the best fruited sours have, but still pretty damn solid.

A big thanks to Jeff for this one. 750ml corked and caged bottle into a Surly teku. Shared with schen9303.

Great bright pink color. Nose is deep. Hints of plastic, vinegar, cranberry and an aggressive, sparkling tartness. Rather muted with some tickling accents. Beer opens tart cranberry. Hints of plastic, virgin oak, cobwebs, vinegar, cranberry and other red fruit. Loads and loads of Brett funk balanced out by a big, juicy, pulpy fruit presence. Very good. Body is light with ample carbonation. Sparkling and aggressive on the palate. Almost champagne-like.

This one's very good. Definitely worth trying.

Vibrant ruby red with white head. On tap at the source.

The cranberries show, but it is fairly funky and medicinal. Lemon acidity. Some oak.

Light bodied. Lovely carbonation.

Okay sour, but too medicinal. I'd like to taste more fruit here.

Poured from the bomber into a Central Waters snifter. Beautiful deep crimson color with white lacing, minimal head. Aroma is all sour cranberry and oak. Taste is almost all sour cranberry. Jammy. A little oaky. Tart, without being puckering. It's not crazy complex, but it's executed really well and shows off the central Wisconsin cranberry. Nice light feel with some effervescence. O'so gets the sour game right again.
