Barrel vs. stainless steel

The choice of storage vessel is one of the most style-determining decisions in the winery. The stainless steel tank is impermeable to oxygen and preserves the wine's primary fruit aromas and fresh acidity intact. It is ideal for aromatic white wines such as Sauvignon Blanc, Riesling and Pinot Grigio, where freshness is central. Oak barrels allow a controlled, small amount of oxygen to permeate through the staves, softening tannins, integrating acidity and creating a round, complex texture. Concrete eggs and amphora are older alternatives that neither allow oxygen as liberally as oak nor isolate as totally as steel, instead yielding a texturally alive, mineral style. Large old wooden casks (Slavonian oak, foudres) are used in Barolo and Rioja for long, oxidative ageing without imparting oak flavour.
