After a long weekend of Octoberfest sampling, here are my ratings, from left to right:
A note about the scale. (1) doesn't mean pure crap. It means it is barely an Octoberfest. In this case, all were good beers. Most just massively better than others.
Hacker-Pschorr - (10) excellent aroma, flavor, mouthfeel
Paulaner - (8) great flavor, nice and smooth
Holbrau - (8) massive flavor, less smooth, almost a bit harsh
Ayinger - (7) very well balanced, good flavor
Spaten - (6) good flavor, well balanced, just a tad bland in comparison to above
Sam Adams (3) just bland overall
