Actually, scratch the 566. Supposedly a less finicky DuPont isolate. I think it might WL585. A guy over HBT did side by side 3726 and 585 and said exact! Looks like White Labs seasonal for July. I could wait that long.
MoreBeer lists Imperial Rustic as equivalent to 3726. Never used it, so I can't vouch for it.
Thanks Stevie! LHBS said the WL release release is typically END of July so that's a little longer to wait. I'll be the guinea pig. Just ordered Rustic. Never even heard of them or this yeast. EXCITED!
