- How long do unopened ready-to-drink margaritas last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of ready-to-drink margaritas, store in a cool, dry area.
How long do unopened ready-to-drink margaritas last at room temperature? Properly stored, an unopened bottle of ready-to-drink margaritas will generally stay at best quality for about 18 months, although it will usually remain safe to use after that.
Are unopened ready-to-drink margaritas safe to use after the "expiration" date on the bottle? Yes, provided they are properly stored and the bottle is undamaged - commercially packaged ready-to-drink margaritas will typically carry a "Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the ready-to-drink margaritas will remain at peak quality.
Storage time shown is for best quality only - after that, the ready-to-drink margaritas' texture, color or flavor may change, but in most cases, they will still be safe to consume if they have been stored properly, the bottle is undamaged, and there are no signs of spoilage (see below).
How can you tell if ready-to-drink margaritas are bad or spoiled? The best way is to smell and look at the ready-to-drink margaritas: if the ready-to-drink margaritas develop an off odor, flavor or appearance, or if mold appears, they should be discarded.
