Funny, there's a winery on the Silverado trail that when you ask to have a taste of their oil, they pour it into a glass just like they just poured your wine.

And you never give them any back

I prefer local ones when I go to California, stuff I can taste there to see how it is. The more grass and pepper flavors, the more I like it.

Of course, if we are in Italy and one of the wife's relatives happens to offer us some of the stuff from their property to take back, well that's worth trying to sneak through

If we do have to buy in a store between trips, it's usually either Italian or Greek.
