Well, today it’s good to hear that supply and prices shouldn’t be affected, although I wonder if that only applies to commercial brewers with contracts.
FWIW, if you’re pressed for an alternative to Czech Saaz, I highly recommend Ultra. I got some from Freshops this spring and I’ve been using them in every recipe calling for a noble hop since. They are the closest thing to Saaz I’ve tried. They smell and taste fantastic, with a touch of that cinnamon note I get from Saaz.
Ultra is actually 1/6 Saaz (2/3 HMf and 1/6 ??? as well). But I take hop lineage with a grain of salt as Cascade was bred from Fuggles, and Citra was bred from Hallertauer and Tett.
Having said that, Sterling is on my hop wish list and I’ll probably snap some up if I see a good deal on them in bulk this season.
