The idea is that "riper" tannins will taste softer but still impart some of the texture components found favorable in wine. In winemaking, the amount of the time that the must spends in contact with the grape skins, stems and seeds will influence the amount of tannins that are present in the wine with wines subjected to longer maceration period having more tannin extract. Following harvest, stems are normally picked out and discarded prior to fermentation but some winemakers may intentionally leave in a few stems for varieties low in tannins (like Pinot noir) in order to increase the tannic extract in the wine. If there is an excess in the amount of tannins in the wine, winemakers can use various <a href="/wiki/Fining_(wine)" class="mw-redirect" title="Fining (wine)">fining</a> agents like <a href="/wiki/Albumin" title="Albumin">albumin</a>, <a href="/wiki/Casein" title="Casein">casein</a> and <a href="/wiki/Gelatin" title="Gelatin">gelatin</a> that can bind to tannins molecule and <a href="/wiki/Precipitate" class="mw-redirect" title="Precipitate">precipitate</a> them out as sediments.
