The Mn1200 has not been released and may never be for whatever reasons. The breeding program at Minnesota has been shaken up a bit with Peter Hempsted being let go. Not a lot of info on that yet. It is a much more complex grape than Marquette, but is smaller and needs to ripen well or can be a bit vegetal or green tasting. The wines are superb since they have a very high skin and seed to juice ratio. Mainstream wine drinkers like Marquette better if done well, but real conniseurs prefer the Mn1200 hands down. It is a very good drinking wine being lower in acid than Marquette at two years, but when it hits three years it really shines. I have my small planting of about 100 vines of the Mn1200 so generally make a few hundred bottles of it a year since it is lower yielding than Marquette.
