Sektfest Eltville ★ 4.2
A first-weekend-in-July sparkling-wine festival on the Eltville riverfront, with stands from Sekt houses including Schloss Vaux, Wegeler and other local Sekt makers pouring traditional-method Riesling and Spaetburgunder Sekt.
Tip: Combine the festival with a guided tour at Schloss Vaux a few streets back; both lean on traditional-method Riesling Sekt.
