I did not know that you could share the "clinics" either. In the one that I watched, I don't recall anyone sharing. It is a good idea. One of the other classes that I noticed was a Tequila-tasting class in the Mexican restaurant. I gave up drinking this particular drink many years ago and have not had a taste of it since. It is hard for me to imagine that the different brands can taste much different than the others. I guess after you have had the first one, they all taste the same.
