No, it isn’t

Yes, there are some people who do “wine tasting” just to get shitfaced. But if you go to any ACTUAL wine tasting (whether it is in the back of a Total Wine or at a fancy vineyard), basically everyone is expected to spit out the wine. Depending on the “methodology” you may swallow a small amount, but it is really like one sip per glass/wine.

And the person who does just chug each glass? This isn’t Parks and Recs where everyone bows to the almighty prankster. They get their asses thrown out.

Now, whether people can tell the difference between six different syrahs whether they spit or swallow is a very different topic entirely. But if the goal is to get drunk, “wine tasting” is a horrible way to do it.
