Hi gimmebeer: I always use yeast nutrient, yeast energizer & DAP (diammonium phosphate) in a wine/mead must. I've never used pasteur red, but I've virtually eliminated the sulfur generation from montrachet just by adding those nutrients. I've read where others on this site made Ed Wort's apfelwein & had a terrible stench for a few days or a week, I've got 3 gallons fermenting under my desk & even when I put my nose right up to the airlock for a sniff, I can barely detect any sulfur at all; and montrachet is known for producing sulfur. That's my 2 cents worth, hope you find this info useful, GF.
