Aging Vessels
A fermentation and aging vessel does not determine how a wine tastes, but rather the conditions under which it matures. Whether wood, concrete, clay, or stainless steel: the choice primarily controls how much oxygen reaches the wine over the months, how stable its temperature remains, and how its texture develops.
The perceptible difference in the glass rarely arises from the material itself, but rather from the processes taking place within it. Understanding this means interpreting a vessel not as a promise of taste, but as a tool with clear physical properties.
Oxygen is the real adjusting screw
The most important difference between the vessels lies in how much oxygen they release into the wine over time. A new, tight-grained oak barrel lets roughly twenty to thirty milligrams of oxygen per liter pass into the wine in the first year; a barrel that has already been filled several times lets in significantly less. Stainless steel is almost airtight and excludes oxygen almost completely. Concrete sits in between, and clay vessels vary especially widely depending on firing temperature and wall thickness: the hotter the clay is fired, the finer the pores and the lower the exchange. These small amounts, spread over months, help decide how soft the tannins become and how calmly a wine later arrives in the bottle.
Why vessels shape texture, not aroma
Where new wood does release aromas — vanilla, toasted notes or spice — concrete, stone and clay remain neutral in taste. Their contribution is tactile: they shift how a wine feels on the palate, and with it its texture. Concrete holds the tension of a young wine because it stores heat slowly and contributes hardly any aromas; clay allows a gentle micro-oxidation that rounds the tannins without adding wood notes; stainless steel preserves fruit and freshness in their original form.
The impression of austerity or reduction often attributed to amphorae usually does not come from the material at all, but from the work around it: from long lees aging and a restrained use of sulfur, as belongs to an aging process with minimal intervention. The vessel accompanies these processes; it does not create them.
The vessel is a decision about time
For us, the choice of vessel belongs to the work of maturation, not to a claim of style. We do not ask which material is currently considered especially original, but how much movement a particular wine can bear and over what timeline its structure is meant to carry. A wine with a firm frame can use the openness of a permeable vessel, whereas a delicate, fruit-driven wine would quickly be overwhelmed in it.
Seen this way, the comparison between amphora, concrete, wood and steel is not a ranking but a question of fit. The vessel creates the frame in which a wine comes into its own; its character it already brings from the vineyard and from the decisions made in the cellar.
