About 2–3 weeks 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.
Apple cider (fresh) 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: Sour or off smell; Cloudiness, sediment, or curdling; Fizzing in a still drink, or a swollen carton or can; A bitter or 'off' first sip. Never taste something to test it — when in doubt, throw it out.
Yes — USDA FoodKeeper v128 gives about Indefinitely in the freezer at 0°F (−18°C). Frozen food stays safe indefinitely; that window is about quality, not safety.
