Comparison
Märzen vs Festbier
Which one is actually Oktoberfest beer?
The short answer
Festbier. The Munich tents have poured the paler, more golden Festbier since the 1970s. Amber Märzen remains a real and excellent style, and is what most beers labelled "Oktoberfest" outside Germany imitate, but it is no longer the beer at Oktoberfest.
