When I brew my Sticke Alt, I exclusively use Spalt hops for flavor and aroma. It has always come out great. The Spalt gives it a very unique flavor and a bit more traditional from what I understand.
Yep. That would be my first choice. Would you be willing to share any details of your recipe?
This is the recipe I've used most often (I've tried a few variations). I prefer to use all Spalt hops when I can, but sometimes I can't get enough in which case I've bittered with Saaz instead. Around 70%-75% efficiency so it's usually around 1.061 for a final 5.8-6.0 abv. I've never had a problem finding Spalt hops here in the Seattle area (though not always 7 oz's of it) but they're usually a really low alpha like 2.5%. This is for 40 ibu's using a 2.5% alpha. After writing this one up, I think I'll need to brew this again soon. Quarantining makes for plenty of brew time.
