Never used it for an Altbier, but US-05 is my go-to, always-have-some-on-hand yeast, and I use it for a lot of Pale Ales and IPAs. Maybe get some Notty for Altbiers. It will also work well for Pale Ales and IPAs with good temp control.
You can't be a real country unless you have a beer and an airline. It helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer. -Frank Zappa
