Short definition
Inert fermentation and aging vessels that preserve pure fruit character without adding oak flavors.
Stainless steel tanks add nothing to the wine — no vanilla, no toast, no spice. That is the point. Winemakers choose steel when they want the grape variety and terroir to shine through unmasked. Sauvignon Blanc, [Pinot Grigio](/wines/pinot-grigio), Albariño, and Muscadet are almost always fermented and aged in steel. The result is clean, bright, and fruit-driven.
