Why not do yor own wine tasting?
Couple of ways to do it:
Do only 5 wines at a time.
Taste like wines, Chards, Cabernets, Merloits or what every. Each vineyard has a differnt taste no matter which grape it is from.
Taste different types of wines:
Start with a Dry White, then a Dry red, next a Blush, then a Sparkling Dry, and lastly a Desert wine, very sweet. This gives you a gamut of what basic tastes are. Go from dry to sweeter as if you start with a Sweeter wine, it will cover the taste of the rest as is a heavier wine and will cover the others of which can be delicate.
Only give a small sip and then an unsalted cracker to clean the palate.
Have a note pad with remarks or just discuss each taste by the drinkers.
After the judgements are made, then the party is on!
