Notes: Key Lime Tau (2π) was brewed in collaboration with Hawkshead Brewery (UK) as part of the Trans-Atlantic Rainbow Project, a series that challenges brewers to come together and brew a beer inspired by a color. In its third year, the 2015 project involved seven UK breweries, each paired with a different American brewery and randomly assigned a color.

Key Lime Tau (7.0% ABV), brewed to embody the color green, is a Mixed Culture Fermentation Ale aged in Oak with Lactose, Fresh Lime Peel and Fresh Lemongrass.

A-burnt orange, modest head that dissipated quickly
S-grassy and funky. Must be from the yeast
T-acidic tart/sweet. oaky
M-Light (+) body, below average carbonation.
O-wierd. My palete would start to say "this is pretty good", then all of sudden I would catch a wave of vinegar or something.

Copper colored with a trace of off white around a quarter of the rim. The aroma is of lemongrass and lime. I’m tasting lemongrass and a touch of lime. The mouth is moderately carbonated, but has a nice cooling sensation from the lemongrass.

375ml bottle

Pours slightly hazy amber orange copper with a creamy off-white foam head. Smells zesty, lively and invigorating with fresh lemongrass, key lime peel, lemon, some malt, and creamy vanilla-like lactose. Tastes like key lime pie, fresh lemongrass, tart lemon, lime peel, creamy lactose, sweet spice, oak barrel, bready caramelized malts, with floral earthy grassy hops. Feels medium bodied, creamy with smooth moderate carbonation. Overall a real nice key lime pie inspired wild ale.

Lightly hazy, golden and dry...the head is thick and white with intricate lace. Flavorful, tart....lime tang...wonderful. There is a bit of pale malt underneath. The finish is dry and acidic. Medium body and enjoyable.

Translucent dark orange, brownish ale, topped with a decent head - about 1 finger from a turbulent pour.

Musty oak, tannin, vinegar, and lime come together in a tart, funky, slightly muddled package.

Flavor follows. It's an odd (but pleasant) mix of sweet, sour, and funky. Brown sugar, key limes, honey, oak, tannin, and mild vinegar. Only mildly sour.

Smooth and oily on the palate.

This is a very good wild ale. The aroma of lime hits you right in the face. The taste of the lime comes through as well with a bit of sweetness from the lactose. The name certainly fits the beer.

375ml bottle, of uncertain age, but I think it was on sale so probably old. Hazy copper orange, but may have a tint of green around the edges. Medium size bubbles around the edges, but more of a film than a head. Amazingly, smells like a key lime pie including a whiff of the crust. Taste is tart, limey, some sweetness (lactose it seems). Feel is nice, rich and a little creamy. Overall, this was a fascinating variant of a wild ale. It has the wild ale tartness, and that is base that plays into the recreation of a key lime pie flavor. I guess the notes of baked crust are coming from the oak and malts, the lime flavors are just right, and the lactose gives the sweetness for the pie filling.

Sample at Mikkeller Beer Celebration Copenhagen 2018, Blue Session. Aroma is zesty and fruity with marmalade and fruit jam notes. Taste is sour, sweet, fruity, mineral and a bit salty with a light orange rind bitterness on the finish.

A: Poured into a tulip to a deep orange topped by a dense two finger off white head which fades slowly to a collar around the edge of the glass with minimal lacing
S: Smells of funky yeast and some grassy notes with some hints of lime
T: Taste is tart acidity with some key lime notes, lactose sweetness with some cream, slight funk, and grass notes. Swallow is more key lime with some lingering tartness and sweetness from the lactose.
M: This beer has a medium body with a slightly creamy mouthfeel. Carbonation is just below prickly while the beer has a drying finish from the acidity.
O: Overall this is a really great beer that seemed to hit the flavor profile they were looking for. Very nice with some good complexity and flavors which makes this one an enjoyable drink. Definitely worth a try if you like key lime pie.

Aroma is big lime/key lime and sweet fruit. The flavor is lime/key lime, malts, fruit and a mix of big tart and slightly sugary sweetness in the finish.

Crooked Stave - Key Lime Tau
Key Lime Wild Ale with Lactose - 6.3% abv

L - 2-finger off-white head atop a burnt orange body.

S - key lime, sugar, graham cracker, oak.

T - quite sweet. Very acidic due to the limes. A slight tartness but less than expected. Barrel presence is faint but pleasing.

F - medium body, prickly carbonation. Not detecting what the lactose is doing here.

O - A decent wild ale, but comes off as more of a fruit beer due to the low degree of tartness. Pleasing on a 75 degree October day.

7/1...pours copper blended with gold, foam on the low side. Key lime nose, tart scents and loads of the lime citrus. Oak hits you first, a key lime pie like taste. Pulpy lime mouthfeel. Bitter.
