Finally, it's fair to say that Americans.

Will drink a good deal of wine tomorrow with their Thanksgiving feasts. But if we were to ask who makes the world's greatest wine tonight, we have an answer that may surprise you.

At Schaefer Vineyards, Elias Fernandez walks row after row, checking the vines, the grapes, and feeling the sun.

The sun reminds me a lot as a kid growing up because I did a lot of work out in the fields.

A pioneer in the Napa Valley, elias has gone from migrant worker to master winemaker.

Been doing this for 40 years. Wow. This will be my 40th harvest.

Along the way, studying viticulture in college and creating this 2008 vintage, which won wine spectators coveted wine of the year.

Do you think you're a better winemaker because you've lived on those fields?

Yes, I definitely do, because I can connect with the people in the fields very easily. So to me, it gives me a little bit of edge, for sure.

That edge shared by a growing group of Hispanics now shaking up the billion dollar wine industry.

Are Mexican Americans making some of the best wine on this planet?

For sure.

And they're doing it right here in Napa Valley and other parts of California.

Senior editor james molesworth tastes, rates and rights for wine spectator. He's noticing more and more Hispanics making their mark.

I think what you have there is probably a little more soul, which is hard to quantify, of course, but again, it's that if your family name is on this bottle, you're taking it very seriously.

For this family, oscar, his wife Lola, and their nephew, there was just one name for their wine.

My first thought was, yama, we have to honor our family name here in the Napa Valley.

A great name, but no relation to this reporter.

It's really hard. And that's been our biggest challenge, is we are this small brand competing with a lot of big guys out there.

They're betting wine drinkers appreciate not only their big, bold cabernet, but also from planting to blending to bottling. One family did it all.

And I think that it's really time to highlight those individuals that farm these grapes. And I think it's kind of a responsibility of ours to bring full circle winemaking in the Napa Valley. For the Mexican American vitners from the.

Fields to the cellars to your dinner table, the American dream in a glass.
