I like to watch Wine reviews before buying them. I am kind of following many wine reviewers on youtube. But none of them seem to be follow worthy. And on that point I can tell you it'd be worth to consider finding a better youtube channel. Do you know any channel where you can find some decent reviews of the wine? Do you watch any specific youtube channel?
WineLibraryTV by Gary Vaynerchuck is definitely my favorite: there are over a thousand episodes you can watch and the guy knows his stuff. Here's the first one:
Yes his style to review is definitely good. Though videos are pretty much old as in 6 year old or more. He is in 40s now. He started when he was in 30s. So many of those brands don't have around anymore. But yeah still a good channel to keep track of and watch.
