Full disclaimer here: I know that most of these Americanized version of noble hops are considered very close to the originals, but I feel like I get a bit of a citrusy character from American versions of traditional noble hops. This is a very new theory of mine. I just carbed up a pils that used a bunch of liberty for a mash hop, bittering, and mid boil addition. I used 4 ounces of Czech saaz hops within the last 10 mins of the boil. I didn't expect any citrus at all, but there it is. It tastes amazing, but I was not expecting it at all.
