Scott:

Sorry that I (and others) jumped to the conclusion that you weren't
following the instructions. For example, I thought that WE
instructions were specific about how much K-meta to add.

Yes, if you are planning on aging a VR kit for length of time adding
extra meta-bisulphite is recommended. The WE Selections instructions
that I just checked online say 1/4 tsp K-meta per batch. Note this is
NOT true of all kits, and is not even true of all WE kits (extra meta
not required with WE Crushendo kits, I believe).

You still haven't mentioned, that I noticed, what brand the Cab and
Tempranillo are. Somebody else already mentioned that WE doesn't
recommend changing yeasts. I have read that wine yeast changes in
kits are noticable when the wine is young, but not after it has aged.
