I discovered Pietra in Switzerland back in December. The most remarkable thing about it, from the outside, is it's from Corsica. I've never had a beer from Corsica. Advertised as ambrée on the label it's certainly that on pouring: a limpid red-gold. Little by way of aroma, and the taste isn't up to much either.
It's dry, for the most part, complicated only by a slightly kippery smokiness which works to reduce its refreshment quotient quite considerably. The body is thin and I'd never have twigged it was 6% ABV, but at least you get some bang for your buck.
I won't be hunting down six-packs of this next time I'm in Corsica.
