I admittedly have little experience with non-American hops other than magnum, northern brewer, perle, EKG. I brew some close to authentic styles but nothing spot on. I am on a reasonably tight brewing budget so spending more on imported hops with really low AA% is hard for me to justify when I can use half as much of a more affordable hop that I like and works for my purposes. I will say that I understand the quality of ingredients as well as their appropriate use is very important when making authentic styles. This is a sacrifice I am willing to take to a certain extent.
For example, I just kegged a 'moktoberfest' brewed with Magnum and N Brewer hops instead of noble hops. I think this will be fine for my novice palate especially for a malty style like this...
To my question, are there any recommendations for hops with higher alpha ratings that are 'similar' to some noble hops varieties? Something like Northern Brewer, Perle, etc. I realize that to get a noble hop character you need to use noble hops. I am curious what others think and assume that none really fit the bill. I understand that some American examples have been compared to noble varieties but those seem to have very low AA% as well.
