Will the vinyard be giving you guys tips? Since you're not a wine drinker, there's some more basics to serving wine.

1) present the bottle to the one who ordered it. This allows them to make sure you've brought the bottle they want.

2) uncork. Set the cork on the table next to the bottle.

3) Pour a small bit (about 1-2 sips) into the orderer's glass. They'll taste it and let you know if it's ok. They'll nod or something and then you can pour everyone.

I would recommend not picking up their glasses unless you have problems reaching. I don't personally cup my red, and wouldn't like a waiter handling my glass unless absolutely necessary, but that's just my feelings, the vinyard might have instructions or something for how you're supposed to pour.

Have fun! Funny that you don't drink wine though... maybe now is the time to learn?
