That's what my family called Weihenstephaner Hefeweizen. It was one of the few good beers I could get them to drink at Rich O's.
I went there today for a pizza, and saw to my delight that they had good old WeffenSteffen on tap. It was as delicious as ever. I was a little ashamed when I checked my app and saw that I hadn't had it since 2015.
