I just bought US Tettnager with an Alpha Acid of 6.1%. Before I used German Tettnager with an AA of 3.9%. If I adjust the ammount proportional to the AA % will my Koelsch taste the same? The math would be:
3.9%/6.1% * 68g = 43g (used in my 10gal Kolesch recipe)

Yes, for bittering
No, for flavor/aroma

I.e., I'd keep your later additions the same, but use less bittering.

Understand that US Tettnager is actually a British Fuggles derivative, not a German type hop.
