14 Rules for Visiting a Tasting Room
Some other tips from a comment:
"If you're going to spit bring your own "spittoon." I bring a red Solo cup.
You don't need to buy--you're shopping.
You definitely don't need to tip. You can if you want, but not mandatory. Tourists see a primed tip jar and think they're supposed to.
Don't show up five minutes before closing and expect a full tasting."
Highlights (last one especially on RPM Tours!):
Go ahead and swallow. There’s no need to spit. “It’s not all about education,” Jones says. “It’s okay to drink a little and have some fun.”
But spit if you’re visiting a lot of tasting rooms, “moderate your intake,” Margerum says. “The bane of tasting rooms are drunk tasters.”
If you're only going to 1 or 2 wineries, you don't need to spit. But any more, and you will need to do so. Especially as you might end up buying something that once you taste it at home wonder "What was I thinking?".
