Sediment in wine means the wine is slightly flawed.
Answer: False.
Sediment is not a flaw but rather a natural process that occurs over time. Sediment—molecules of color and tannin that precipitate out of solution—are generally present only in older red wines (10-plus years old) that had a lot of color and tannin to begin with and that were not fined or filtered. You can drink an old wine that has thrown some sediment without decanting it; the sediment is not harmful, just slightly teeth-clinging.
