Sounds good to me. 50 degrees latitude is about the farthest you can go to grow grapes for wine. The Mosel flows into the Rhine at Koblenz, about 50.3 degrees.
My favorite winery in Germany is in Briedel, and they're at 50.02. Winemakers grow their grapes on one side of the river, the side that receives the most sun. With global warming, they'd be able to grow grapes on both sides of the river, so I'm all for global warming...lol.
I was reading up on French wine classifications a while back. The best wines which are grand cru often come from just a narrow band on the hillside. The band may only be a few hundred feet in depth. Too low on the hillside, grapes don’t get enough sunlight. Too high on the hillside, the temperature maybe to low. I am sure the winery’s outside of the grand cru zone are rooting for climate change...
