The only red worth purchasing from Louis Latour is their Corton Grancey. It’s a blend of four Grand Cru vineyards, and with a little bottle age can be somewhat interesting. I had a '79 recently that was quite nice. And only if you can get it at a bargain price.
I would kindly have to disagree, their RSV is a solid tier (or two) above the Corton Grancey, especially in 2014 and 2015. However, for 1/3 the cost, it’s definitely better QPR for grand cru.
