Seriously, I didn't even finish my PhD.
I'm not sure whether I like the taste, or just knowing there is antioxidant in there. So $200, $20, or $10 a bottle, doesn't matter to me. 4L for $15, seems good deal to me. Each time I got a couple case of typical lager, and 3-4 such bottles.
I do feel good, when putting my Zegna on, several times a year. I do feel good too, when most of time wearing university shirts. It's just me vs. material: I like lobster but egg white is perfectly fine, we have BMW and I drive 200+K van all the time. Money is biatch.
Don't get me wrong though, I do like 五粮液、Cognac. I do get multi-grain bread all the time, again not because of taste.
