I'm a big fan of Sterling. I do find it to have some fruity undertones that are beyond what I typically pick up from noble hops, which is fine for most of my purposes, but something to keep in mind. I like Ultra a lot, and I use it as a substitute for Saaz quite a bit. It has a lot of the same herbal/spice notes I get from Saaz, but with less of the lemonade character I pick up from Sterling.
As far as hop requests go, I say just keep 'em coming. I love trying out all the new varieties and trying to figure out where they belong in my brewers toolkit.
Some specific requests:
- Some sort of Super Motueka. I love the lime zest/lemongrass notes I get from Motueka, but most typical IPA hops just drown it out in a blend.
- Any other sort of flavor/aroma that can be difficult to get in your finished beer. If I saw a new hop variety that was described as something like Orange Blossom Honey, I'd be all over it.
