I don’t drink a lot of commercial beer, but I had a few Octoberfests in my fridge and thought it would be fun to do a side by side comparison.
First up is Paulaner Oktoberfest Märzen. The picture below doesn’t catch the color quite right, it is a golden orange tone, and is gin clear. The aroma was mostly crackers and wheat toast, and the flavor was much of the same. It is malty rich, with enough of an acid balance to keep it refreshing. I definitely get a hint of a lactic flavor; not tartness, but as if I was drinking a Berliner Weisse before and hadn’t rinsed my glass.
Next was Ayinger Oktoberfest Märzen. The Ayinger had a faint haze and it really made the orange color pop. The nose was crackers and bread crust with a bit of nuttiness. The flavor was similar to the aroma, mainly wheat bread crust with a hint of toasted chestnuts. It was a bit richer than the Paulaner and had less crackery flavor, along with having a nuttiness that wasn’t in the Paulaner. It also had the same hint of lactic flavor.
Last was Sam Adam’s Octoberfest. The SA was gin clear with a darker, orange-amber color. The nose was largely wheat crust. Flavor was more wheat crust with a similar toasted chestnut note in the background that the Ayinger had. Of note, I get no notes of caramel, toffee, raisins, or sweetness. It has a nice acidity balance to help it finish, but zero lactic flavor. It isn’t quite as malty rich as the two German Märzens, but it is certainly in a similar flavor ballpark.
My big takeaways here are that the distinct characteristic separating the German beers from the Sam Adams is a distinct lactic flavor. I don’t know if I have the time or determination to start my own Saurgut reactor, but I will at least be trying out some Saurmalz in the near future.
My other takeaway is that Sam Adams Octoberfest was neither sweet nor caramelly in any way. Honestly, aside from the color and lack of lactic flavor, it holds its own with the German Märzens and is an excellent example of the style in its own right.
