Yes, hubby and I have done it
We love it.
Yes it is pricy it
It is very interesting
If you've ever done the Tequila lunch pairing that they used to do during food and wine it's quite similar, sans the food portion of course.
But they teach you the flavors and notes and tastings of tequila just like they did in the pairings.
Ours with just DH and I.
They made it sound like it is always just done with 1 group but I'm not sure about that.
We would do it again.
