About Until the package use-by date at 40°F (4°C) or below, according to USDA FoodKeeper v128. That window runs from the day you bought it — FoodKeeper publishes no separate after-opening figure for this one.
Cooking wine is shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: Mould around the rim, cap, or surface; An off, fermented, or yeasty smell; Fizzing, bubbling, or a bulging lid; Separation or a colour change that won't stir back in. Those are the general signs for condiments & sauces — USDA FoodKeeper v128 publishes no spoilage note for Cooking wine specifically. Never taste something to test it — when in doubt, throw it out.
