There is, of course, ICV-GRE, which is kinda for Grenache.
MoreWine! has suggestions (including GRE, SYR, RP15, D254, BDX, and BM45) here:http://morewinemaking.com/public/pdf/wyeastpair.pdf
Usually after the crush, add SO2 (30 to 50 ppm). The next day, hydrate yeast with GoFerm. Once a cap forms, add Ferm-K (half the total dose). Add the 2nd half dose of Ferm-K nutrient once you are through 1/3 of the total fermentation.
Here's a good guide.....
