It looks like you just did compare coke to wine. :P Seriously though, isn’t this a straw man argument? Parent wasn’t saying there isn’t craft or tradition involved in wine, nor that coke compares on those axes. You didn’t actually answer the question at all: why not discuss the cultural impact of coke? There is cultural impact. It’s not the same impact wine has, it’s quite different, but it is in fact there, don’t you agree?
I answered this in a sibling comment in more detail, but basically my complaint is that comparing a single soda brand to an entire class of tens, possibly hundreds of thousands of drinks, which have a rich cultural back story just seems wrong to me, that doesn’t do wine justice, especially as we don’t just discuss cultural impact, but cultural significance. I’m sure I come across as a European snob here, and I’m actually sorry for that, but I can’t get over the fact that someone claims Coca Cola is in any way as significant as the tradition of winery in total :(
Nobody claimed Coke is as historically significant as all wines combined. That is the straw man. As the best selling single soda brand, and a major global export that people in almost every country on earth consume, Coke does in fact have global cultural and economic significance, which is just a fact. That fact is not taking anything away from the rich history of winemaking, so there’s no need to be defensive. Have some wine and relax!
Edit: BTW Coca Cola’s revenue does stack up meaningfully against the entire wine industry. (The Google results are all over the map, so I’m being careful with my claims, but according to some web pages out there, Coca-Cola’s net revenue is higher than all wines combined.) There is an economic basis for comparing Coke to wine, which does support a cultural basis for comparison, in addition to other reasons Coke is culturally relevant. Notice I’m not (and upstream comments were not) coming to any conclusions about the result of that comparison.
