I have made Marquette using a variety of wine yeasts but the best, in my opinion is Lalvin 7122B, which gives a nice mildly fruity wine that is very popular with guests who try it. Marquette is relatively low in nose and flavour profiles and 7122B seems best in compensating for this. Also, 7122B metabolizes some malic acid but the wine must also be allowed to undergo malolactic fermentation for best results. I also add some supplemental tannin (Tan'cor Grand Cru, or QuerPlus or Quertanin Sweet) several months before bottling (one year after vintage) and leave in bottle for at least 4 months before drinking.
