So let's talk about about what styles the 3 hops work well in. For instance, isn't Spalt traditionally used a lot in Altbier?
I think I have used spalt and tettnang in a kolsch style beer and couldn't detect a difference with FWH and 20 minute additions. I am not sure my palette can discern between the 3 in the way I would use them so am just curious about others preferences, usage, etc. Just an exercise in curiosity.
