...asked the woman behind me at the Jewel, referring to her Guinness in cans. the checkout woman (with the unfortunate nametag "Donka Y") didn't know, but helpfully mispronounced "draught" (as in, "it hasn't rained in 3 months").
i assured the woman that Guinness Stout is, indeed, dark, which is apparently what she was going for.
i suppose i should forgive her, as i don't know much about wine. otoh, i can usually spot a red vs a white.
