Depth of colour can give you a clue about where the wine was grown and potentially even what grape it could be.
Depth of colour can give you a clue about where the wine was grown and potentially even what grape it could be. Grapes grown in hot climates like Australia or California can have deeper colour. Some varieties like Pinot Noir and Nebbiolo will appear paler and more translucent in the glass. Wines like Zinfandel and Shiraz can have very deep colour, and sometimes they are totally opaque, so I’m mentally perusing what grapes it could be right from the get-go.
