Unpleasantly sour, like a dry export stout but with a more lasting, tacky finish. The real crime, however, is that this doesn't even pretend to taste like cookies. Or even chocolate.
This is... pretty much exactly what it says it is. It's a light, sweet-malt lager, nothing complicated in the base profile. On top of that is a pretty accurate Meyer Lemon sheen that is more essential oil than juicy. Starts citrus, flips over a citrus peel bitterness into bright lager flavors.
Fragrant and hoppy at first but finishes off with a chewy, bready (but not sweet!) malt finish. If you'd told me this was an IPA at the time I would absolutely not have believed you, but everything's always a little different with Anchor.
