Maturation options and effects on tannins Flashcards
(13 cards)
How does oak maturation affect tannin development in red wines?
Oak allows slow oxygen ingress, which softens tannins through polymerization and oxidation, leading to a smoother mouthfeel.
What additional tannins can oak contribute to red wine?
Oak itself contains tannins, especially ellagitannins, which can add structure and astringency, depending on oak type and toast level.
How does the type of oak influence tannin integration?
French oak (tighter grain) imparts finer tannins; American oak (looser grain) contributes more aggressive tannins and flavors.
How does barrel age affect tannin impact?
New barrels impart more tannins and flavor; older barrels contribute less, focusing more on micro-oxygenation.
How does concrete affect tannin development in red wines?
Concrete is slightly porous, allowing gentle oxygen exchange that can soften tannins without adding flavor.
Why might a winemaker choose concrete over oak for tannin management?
Concrete softens tannins while preserving varietal purity and freshness, without adding oak-derived tannins or flavors.
How does stainless steel affect tannin development in red wines?
Stainless steel is inert and airtight, so it does not soften tannins through oxygen exposure or contribute any tannins.
When might stainless steel be preferred for red wine maturation?
When the goal is to preserve primary fruit and maintain firm, youthful tannins without oxidative softening.
How does micro-oxygenation affect tannin development in red wines?
Micro-oxygenation softens tannins by injecting oxygen through the wine, mimicking slow oak ageing.
What is the impact of lees ageing on tannin development in red wines?
Lees ageing can soften tannins and add complexity through autolysis, enhancing mouthfeel and stability.
How do amphorae affect tannin development in red wines?
Amphorae allow gentle oxygen exchange, similar to concrete, preserving purity and softening tannins without adding flavors.
What is the effect of bottle ageing on tannin development in red wines?
Bottle ageing allows slow oxygen ingress through the cork, leading to gradual tannin polymerization and softening over time.
