3.4 AROMA 7/10 APPEARANCE 5/5 TASTE 5/10 PALATE 5/5 OVERALL 12/20
A second example of Kvass that I’ve tried, noticeably different from the other brand (Buket Chuvashii) and I think I very slightly prefer this one. Can from Bell’s Market in NE Philly. Pours very dark brown, coffee-like: almost opaque. About a centimeter of thick, foamy head dissipates quickly, leaving thin but persistent carbonation. Strong aroma of pumpernickle and molasses, hints at worcestershire sauce, soy sauce, or dark rice vinegar. Sweet and sour; neither the sweetness nor sourness is unpleasant. Very balanced. Rich, heavy, extremely filling, like drinking liquid bread.

UPDATED: DEC 15, 2015 Dark ruby color with just a bit of head. Burnt sugar aroma and some dark fruits. Taste follows the nose along with some fruity tartness. Overall seems like a tart cherry drink with some burnt sugar. Not bad at all, expected something different.

Deep brown to black, thick off-white head. Good retention & thick lacing. Aroma of zest, malts, acids, some fruity notes. Light to medium body. Soft carb. The flavour is a well-balanced combination of moderate sweetness & delicate sourness. Same finish. Very solid.

2.7 AROMA 6/10 APPEARANCE 3/5 TASTE 5/10 PALATE 2/5 OVERALL 11/20
CAN 50 CL at 1,2% ABV. Both the aroma and the flavour are dominated by strongly burnt sugar, with notes of smoked dried fruit. Though the sweetness is very high, it does not feel cloying, being somewhat balanced by the light toasty notes, as well as the lactic and fruity acid finish. Carbonation is moderate.

2.6 AROMA 6/10 APPEARANCE 2/5 TASTE 6/10 PALATE 2/5 OVERALL 10/20
Can from a Moscow grocery store. ABV is 1.2%, but can looks exactly the same as the one here. Pours dark brown with a tan head than fizzes away instantly. Aroma of treacle, raisins, brown sugar. Taste is of raisins and sugar. This is probably the most common kvas in Russia, and like most of this country's beer (read pale lagers), it only makes sense to drink it on a hot summer's day.

@ Chriso’s Pre-GBBF Shindig. The pour’s brown with a tiny bubbly head. The nose is straight-up sweet grain, little else. Brown sugar. A touch artificial. The taste is slightly tangy roasted nut, caramel, apple. As thin as it is sweet. Light body, zero carbonation.
