Just wondering if anyone has noticed a change in WY1007? It's been my standard Rhine River ales yeast for decades, but this spring I had a pack (within age specs.) that make a lethargic starter. When pitched I applied the blow-off, which I've usually only needed for this yeast. Slow ferment & a few inches of foam (5 gal wort in 6.5 gal carboy, temp of 70F). Crossed it off as a bad smack pack and ordered another pack from another vendor. In a nutshell, the experience with the second pouch mirrored the first. Both produced OK beers, but definitely was not the explosive experience to which I've been accustomed.
