It is interesting how many American craft lovers will gravitate to the "Americanized Octo". I have to always ask them to distinguish what they want me to brew for the Oktoberfest season - Octoberfest in the American sense, Marzen-style lager, Vienna Lager, Fest Bier, German Helles Exportbier, Helles, etc...usually they will opt for the Americanized Octoberfest, meaning as malty rich and even caramel-leaning as they can get.
I will have to try this years' Weihenstephaner Festbier, if I can get it fresh - usually a questionable venture. The SN Festbier is probably all that I will be able to find in that rarified air for this style.
