Draft at the source. There are multiple styles with similar names, including an amber, a golden sour, and this one. There's also a dry hopped sour. But this is the pale ale. Sadly there's no sour pale ale style on RB, so I entered it as a pale ale, but maybe you could make a case for making it a sour IPA. Anyway: clearish deep golden color, white head. Aroma of tannins vanilla white wine. Taste is sour and bitter and vinous and tannic and complex. Tasty.

Draft at the source. Clearish amber orange color, more or less still. Aroma of orange peel and stonefruit. Taste is softly sour, floral and fruity. Very nice.

Three Penny draught, 8/12/22. Clear brass with maize tones. Medium, white head shows moderate retention. Can smell this thing across the room. Big cherry-like sourness from the bacteria with some earth, cellar, mustiness, oxidation, vanilla and light acetic notes. Sticky honey, dried cherries, vanilla and big Brett notes with lingering but not overbearing acidity. Barrel tannin/oakiness, less oxidation in flavor and lingering Brett, honey and vanilla. Tons of flavor for its size. Soft texture, great malt depth and attenuation. Very Fine, indeed.

Can from Fort Point Market shelf, undated, drunk 6/18/22. Dark copper-golden, good clarity, with a small, white head showing light retention. Soft tannin, golden raisin and juicy citrus with light stone fruit, vanilla and mild oxidation. Moderate acidity with a touch of acetic character. Honey and biscuit from the ample malts helps balance. Juicy apricot, tart lactic and sour acetic notes with big, honey-like malts helping to add a solid texture and good balance. Juicy citrus, apricot, peach and light vanilla and tannin lingering alongside apricot and light acetic acid. Juicy, malty, intensely flavorful and pretty well-balanced, though there is a bit more acetic acid than I'd prefer.

Undated can from Fort Point Market shelf, drunk 6/18/22. Clear ruddy-mahogany with deep cherry hues and a dark beige head that slowly fades to cover/ring. Strong, complex nose showing black pepper, molasses, prune, raisin, maybe even some smokey scotch. Light alcohol, not hot, with a solid base of dry caramel and plentiful, tart red fruits. Souring bacteria lingering, but not dominating. Vanilla, chalk/mineral-laden wine and more molasses as it continues to breath. Cherry, molasses, raisin, caramel, black pepper, strong mineral and strong lactic acidity with a bit of acetic acidity lingering. Vanilla and caramel lingering alongside moderate-to-strong sourness. Fantastically complex barrel notes without being overdone/dominant. Scotch and red wine in the background with lip-smacking caramel and raisin sweetness mostly balancing the strong acidity. Still a heavy brace of cringing acidity at first. Pretty incredible stuff, especially for its size. Doesn't drink like that at all - more in the range of 8-9%. Though there is some inevitable alcohol, it's not hot/sharp. Malts are excellent and barrel tannin helps contribute texture, as well.
