What I have done the past few years is start the mead. I usaully set the brix to about 5 short of the yeast averages. The mead (soon to be pyment) gets to work for about 4-5 days, Then I add the grapes. The thought behind this was that the alcohol already in the mead would take care of any yeasts hitching on the grapes. Which seems to have worked so far.
I feed as a normal traditional mead, maybe a little lighter cause the grapes bring in quite a bit.
I am picking the grapes myself. I have just crushed them by hand or potato smasher.

Real high tech at our house. I could get them from the destemmer I just haven't. I leave the skins and alot of the stem not all but alot. Like you said I figure it would add to it.
At first I was using around 15# of grapes, it was not enough so this past season I used 30# with Chard.. grapes it seemed alot better.
Cap managment much like yours punch down 2-3 times a day. Although I have left the grapes in untill about the end of ferment.
I really don't deal with ph untill the end on anything. I would say about 90% of everything I have brewed I didn't mess with ph it came out good on its own. BUT I will adjust as I see fit in the end. I have wondered if maybe I should be more concerned with ph in the beginning. So far, fingers crossed, my after the fact has been working.

Boy don't you hate it when lazyness pays off.
I have easy access to gamay, chardonnay, pinot noir. From a bio-dynamic vineyard. I don't buy in to the whole bio-dynamics BUT alot of what they do does make for better fruit no doubt about it. Less or no chemicals is always a good thing.
If I can get my hands on enough fermenters I was going to run 3 batch runs of 2 of the grapes. Work work work. That is why I was wondering what you where doing, to help with some of the learning curve. Thank you very much for the info it has been printed and put in the folder.
If you every come up to OR, give me heads up if your interest in some wine tasting, I will get your tasting fee covered and good neighbor pricing on your bottles of wine. At least the 10 winerys that I'm on good terms with. As for the others, they just haven't met my yet.
Because where I live I feel I must come up with a drop dead good pyment using the local grapes.
