Stainless steel

Frequently used material for the production of stainless steel tanks of various sizes (volumes), which are used for the fermentation, storage and ageing of wines. Stainless steel has a high chromium content (as well as nickel, molybdenum and titanium). On the surface, the chromium forms a closed layer with the oxygen in the air (so-called passive layer), which protects the iron in the alloy from rust.

The advantages over tanks made of wood and concrete are easy cleaning, especially of tartar, optimum use of space, flexible volumes (from small tanks of 50 litres up to one million litres), complete protection against oxygen, low shrinkage and better temperature control. The disadvantages are higher purchase costs and slower ageing of the wines. For wine ageing in wooden barrels, see Barrique ageing and Barrel ageing. For a complete list, see barrel types and wine containers.
