I keep forgetting to post what I think is the best one I've had this season
Stortebeker Brewery is in Germany and they did a COLLAB with a very popular craft beer, one of the original from my memories of the 90s
Sierra Nevada "Oktoberfest Festbier" Limited Collab Edition w/Stortebeker 6% ABV IBU 32
-Captures the taste of what you are craving when you open a can of these marzen-lagers, Sierra not known as a big lager brewery to me, more pale ale and IPAs but this hits the bullseye
No doubt the collab works with another brewery from Germany that might have supplied the recipe, perhaps some of the hops as well, who knows?
If you see it, just grab it. Make sure it's the collab edition, there might be another type of festival beer floating around from them
I find this one at Fresh Market $13-$15 6-pack, not cheap
