I have never heard of this grape variety before, now I read this and the next thing I see is Lidl's next week's wine offer for St. Laurent/Spätburgunder wine. I will give it a try!
It is definitely a niche varietal, planted area is still shrinking, especially in my home of Czech republic where it was most planted red grape varietal, but there is growing interest among high end growers in Austria so I think the varietal has some future among wine geeks.
