Key ideas in The Logic of the Wine Label
- Alcohol increases a wine's viscosity, making it feel physically heavier on the palate.
- Tannins are polyphenols from grape skins and seeds that bind to saliva, creating a drying grip.
- Higher ABV wines like Zinfandel or Syrah typically exhibit a fuller body than low-alcohol styles.
- Tannic structure provides the 'backbone' that allows red wines to age and pair with fatty proteins.
- Identifying the primary cause of a wine's physical weight or 'body'
- Distinguishing tannin as a tactile sensation rather than a flavor
- Acidity triggers salivation to cleanse the palate
- Fruitiness is aromatic while sweetness is physical sugar
- Alcohol increases wine body
- High-acid wines provide lift
- Bone-dry definition
- Tannin as a tactile sensation
- The 'finish' is the length of time the wine's flavors linger on the palate after swallowing.
- Applying acidity to balance food richness
- A long, complex finish (30+ seconds) is the hallmark of a high-quality, well-made wine.
- Distinguishing between aromatic fruitiness and actual residual sugar
