Well, I can't thank you all enough for the replies, advice, etc.
I've been reading everything I can on modern home winemaking. I'm a "by the book" engineer, so I want an exact, no doubt perfect road to making wine. And there isn't one. Arg!
But I guess there's beauty in that. If it were just a cookie-cutter operation, what fun would that be?
Opinions sure do vary. For example, I've been reading the very fine print on Jack Keller's web site. And he says (rather emphatically) that when SG reaches 1.010-1.040 in the primary, the must (pretty much all of it) should be transferred (not racked) into the secondary. By "transferred", he means poured (not siphoned). And that the lees should be stirred up good before the transfer, so it (and all the yeast it contains) will be transferred to the secondary as well. Only the massive fruit pulp is to be left behind.
Of course, this contradicts everything I've read elsewhere, but it makes me wonder because Keller is a very successful and well-respected winemaker.
Maybe by the time I'm 83 I'll have this all figured out. That will be 37 years from now.
