As many travelers today are roaming the wine regions of the world, it seems, as haunt the great art houses of Europe. It's an interest the wine-makers have been delighted to encourage, since most wine-tasters inevitably become wine-buyers.

In almost any major wine-producing area, you will be welcomed at vineyards -- large and small -- to sample the local product. You can wander the countryside on your own self-guided tour or join one of the organized trips that are available.

Among the places (and ways) to go wine-tasting from now through the fall:

*Champagne fests from Paris: On a full-day guided outing northeast of Paris, visit a brie factory in Meaux, enjoy a gourmet lunch overlooking the vineyards at Champillon and explore the vast champagne-aging caves of Moe t et Chandon at E'pernay. Tasting afterward, of course. "Champagne and Brie" ($75 per person) is one of 11 one- and three-day wine trips from Paris offered by Cooks' Tours. Frequent departures. For reservations: ITC Travel Services, 727 West 7th St., Suite 1000, Los Angeles, Calif. 90017, (213) 627-8568.

*Balloons over the Napa Valley: Soar above California's premier wine-growing region just north of San Francisco. It's an hour's sunrise flight followed by a champagne celebration, featuring selected labels from the valley's vineyards. Afterward, take a public tour, available daily at many larger wineries, or enjoy a private tasting at one of Napa Valley's great smaller wineries. $125 per person, departing daily from the city of Napa (weather permitting).
