It's Valentine's Day and Jack Dorsey is tweeting about wine.

Or, more precisely, he tweeted a screenshot of a WikiHow article telling people how to properly hold a wine glass. Whatever you do, insists the article with an accompanying picture of a solitary hand holding a glass of wine, "Never hold the bowl." It's real depressing shit.

The Twitter CEO shared the image late Friday afternoon after, we're assuming, his date told him to stop being such a pretentious jerk and just enjoy the nice bottle of Priorat for crying out loud.

Or maybe Dorsey just really likes his whites chilled?

Either way, it's clear that Dorsey wants his followers to know some key wine-related facts.

"Holding a wine glass by the bowl is social taboo, but the reasons for that are as practical as they are polite," reads the article Dorsey shared. "Both the taste and appearance of the wine can be negatively impacted when you hold the bowl."

So there you have it: Hold your glass by the stem (or the base if you're drinking sparkling white and want to be a super asshole about it), and you'll be alright in Dorsey's eyes. Assuming those eyes aren't currently experiencing a little wine-induced double vision, that is.
