Lots of great hops... And I always keep sessionable lagers on tap, around 5.0% ABV.
For actual German hops, I recently brewed a SMaSH beer with 100% Pelton Malt (Mecca Grade is the malter) and 100% Hallertau Tradition Hops (aka German Tradition). Regular Hallertau MF is good but often lower AA as well. And German Tettnanger (
not US Tettnanger, which is rumored to possibly be Fuggles, or to somehow have taken on Fuggles characteristics). Still lagering the Pilsner with Tradition, but the flavor was really very good... Of course Saaz, or Czech Saaz, is a very nice Hop.
Magnum is great for bittering, very clean and higher AA. Use it for bittering, in conjunction with with a lower AA variety for flavor hops.
US Noble (or noble-like) Varieties:
- Santiam: Really like Santiam in flavor additions...more so than as bittering additions. Fabulous aroma! Could always use with Magnum for bittering... Oregon grown Santiam hop is incredible. I have some Washington grown Santiam hops in the freezer now and hopefully they are good too... Terroir exists in Hop production too. Santiam maybe resembles German Tettnanger a little more than German Hallertau. Great hop!
- Liberty: I really like Liberty as well. More similar to German Hallertau. Great hop. Won a best of show (German Pils) with it.
- Crystal: I haven't brewed with it yet but have drank plenty of beers with it. Supposed to be in the same mold, like Liberty, Mt Hood and Ultra. To me it seems a little bit more boisterous than Liberty, but I can't say for certain without more evaluation.
- Ultra is supposed to be great according to one of my local Brewers. Finding a source for it may be challenging.
- Sterling: This one is supposed to match up with Czech Saaz. To me kind of - kind of not. Similar to Santiam, and to Saaz and German Tettnanger but a little different... It has a slight Citrus flavor, which I've welcomed in some beers and certain ones not. Best beer made with Sterling, used it for bittering and some flavor additions but more Saaz than Sterling for flavor additions. That brew didn't really notice Citrus.
- Mt Hood you already know... Nice hop. Can use it throughout the process.
Indie Hops has great info on some of the US bred noble varieties:
