Rhone and other maturation timing

We’ve just picked up a vineyard to manage with a nice melange of varietals.

All of this in 5 Acres of 6x6 VSP.

alicante bouschet
counoise
grenache
grenache Blanc
Marsanne
Mourvedre
Muscat
petit sirah
Rouseanne
syrah
tempranillo
Viognier

its about 2/3 red by acreage, and I’m trying to figure out how many extra fermenters I’ll need. With our purchased Burgundies and estate Bordeaux we generally don’t conflict, but our Bordeaux vineyards and other Syrah can all come in the same two weeks.

Any idea how to predict relative harvest dates? The whites are not an issue we’ll barrel ferment them, just counting up the 48" fermenters I’ll need.

Given even cropload, soils composition and rootstock, the Syrah, Tempranillo and Viognier will be the earliest, followed by the Grenache, Petite Sirah and Counoise, with Mourvedre bringing up the tail end. Timing on the whites will depend on what you’re trying to do with them. I’m not familiar with picking Alicante Bouschet. You’ll probably be able to use the same fermenters in three waves with your middle wave being the biggest, if I had to guess.

Thanks! thats what I needed to know.
