I’ve been looking for a PV kit as well. It’s hard to find one. Been thinking about a juice bucket, but not happy with any of the ones I’ve seen. I’ve also seen a few LR Pv’s, but most are blends. If you find a good one, let me know!
I thought the same thing, and scoured the universe last fall until I found one. It is in bulk aging now. However, I noticed that S.H. in Florida has them listed again! It is the Australian P.V.--International Selection from Wine Expert. I had to abbreviate the name, as to mention it is verboten on this site. I've had good luck with them though.
