What Wine Has Most Tannins?
Cabernet Sauvignon is a wine that typically has the highest level of tannins, thanks in part to its thick skins and small berries. This grape variety is often blended with Merlot and other varietals to balance out its astringency and create a more complex wine. Tannins from the grapes create a dry sensation in the mouth that gives the wine structure and allows it to age well.
