Yes, it was/is Qoullfrisch!! One of the cleanest lagers around and, by far, the best of the buch from the larger Swiss brewerys. It's availible in C, used to be in Y but when I wrote a letter to Swiss complaining about taking it out of Y, I got a lame excuse that the Appenzeller brewery could not make enough!...Ha....I wrote back that if they could not make enough, how come you can buy it in any COOP market! Alas, Swiss would rather pay more for the green can for Y than less money for a really good "home" beer.
