I love Marquette and drink it regularly (both ours and what I can occasionally find from other wineries). It definitely has a pronounced nose to it when young, but I don't think of it as "foxy." To me, it is more exotic than that - I always think of men's cologne, maybe vaguely Drakkar Noir-ish. That exotic aroma seems to fade as it gets a few years' age on it, and it becomes much more like a pinot noir. So to me, 1-2 year Marquette is very different than, say, 3-5 year old Marquette. Both lovely, but in different ways.
For the past 2 years we have blended it with Petite Pearl. In 2019 it was roughly a 50/50 field blend of the two. It was the first year we got a meaningful harvest off them, but it still wasn't much. Plus, they both seemed to ripen at about the same time. Which is why they were fermented together from day 1. It turned out absolutely lovely. I am thoroughly delighted, as this was the first red wine we made with grapes from our own vineyard. The PP seems to lend flavors of both cherry candy and a touch of evergreen, in addition to boosting the tannins. We only got about 2 cases, so we kept it all for ourselves and try a bottle every month or so to see how it is aging.
2020 we harvested a lot more of both varieties, but it was a difficult year, so it's hard to know how it's going to turn out. Marquette ripened a week or so ahead of PP, so we had to ferment them separately, then combine them in barrels a few weeks later.
