Lillet Rouge is ruby red, squeezed from merlot and cabernet sauvignon grapes. It noses and tastes of grape (like grape soda), vanilla, and orange. It's bitter notes strike me as more substantial and lasting, hence, those new to aperitifs might well begin with Lillet Blanc and then graduate to Lillet Rouge. Or, you might well mix four ounces of Lillet Rouge with four ounces of club soda and adorn with a slice of orange to make a fizzy aperitif.
