Thumbs up here, too. I just tapped a mid-May brewed (LODO) Idaho Pure Pilsner, fermented with S-189. My palate says it has a slightly sweeter profile than Weyermann, but not offensively sweet or anything nearing cloying. I did not do head to head blind triangle testing, so take this as purely anecdotal comments.
These specialty malts are going to catch on, I believe.
