Key ideas in Mastering the Blind Pour
- White wines gain color and turn darker as they age
- Young white wines are typically pale or straw-colored
- Red wines lose pigment and become lighter over time
- Color particles in red wine fall out of the liquid as it sits
- How white wine color shifts with age
- The relationship between red wine age and color intensity
- Color intensity in red wine comes primarily from the skins
- White wines move from pale to gold/amber
- Thin-skinned grapes produce translucent, pale wines
- Deducing grape skin thickness from transparency
- Red wines move from purple/ruby to garnet/tawny
- Mapping specific colors to wine age stages
- Hot, sunny climates produce grapes with thicker, darker skins
- White wine starts light and gains yellow/brown tones
- High sun exposure leads to higher color concentration in the juice
- Amber and brown indicate significant oxygen exposure over time

Here's what playing it feels like
A real question from this course. Take your best guess.
