You may find my ratings high - probably that’s because I try to be positive about beer :)Here’s some brief guide:
5.0 - a godlike beer, probably non-existent :)
4.0-4.9 - great beers that I adore and drink with real pleasure
3.5-4.0 - not quite the elite, but still very good and definitely recommended
3.0-3.5 - good ones, definitely over the average, very enjoyable. For me the 3.0 grade is the point where good things start.
2.5.-3.0 - just OK beers; drinkable but nothing great
2.0-2.5 - Nothing interesting. Drink only if there’s nothing better around
2.0 and lower - run away
Cheers!
