The Hofbräu Festbier weighs in at 6.3% and has a very faint citric aroma on a bready base. I found it to be dryish, verging towards sour grapefruit and perhaps bitter almond. Perhaps a little astringent. This all sits on a toasty, biscuity backdrop, but the hops to stay to the fore. Given its strength, it's not surprising a slight alcohol warmth comes out too.
This isn't bad, but I came away from it thinking I probably wouldn't drink more than one as it felt a little lacking in body. I expect my festive beers to be a little more luscious, but still, it's the thought that counts.
