I really don't think that much red Burgundy is consumed, but a decent amount of whites are purchased here in the US. The tariffs on Burgundy alone won't kill the retailers. But Champagne is a different product than sparkling wine from Gruet or Korbel or Schramsberg, to name a few. Yes, they all are liquid and have bubbles. But most of us on the WS forum would not mistake a grower Champagne or even a NV Charles Heidseick for Cold Duck.
I sort of doubt that there will be significant job growth in the domestic wine production area if the tariffs are enacted. I personally favor freedom, free trade, and the maximum exposure to consumers of products of their personal choice.
