Concept

lignin

A glowing orange droplet emits smoke, flanked by two bare trees on a dark background, symbolizing the transformation of lignin under heat.

A complex organic polymer that forms key structural materials in the support tissues of most plants, giving wood its rigidity. When subjected to the intense heat of barrel charring, lignin degrades into phenolic compounds, releasing flavours of vanilla, spice, and smoke into the aging liquid.
