Each bottle of Baileys carries an expiration date printed on the label. Try to stick to this date before you consume it. The good news is, just like many other processed food, Baileys may last longer than its expiration date, with proper storage. The extra lifespan might be for several months. However, quality is not guaranteed anymore. If you just can’t waste a good bottle of expired Baileys, try to do a quick check on the look, smell, and taste. If undesirable changes are observed, it is likely safe for consumption. But, if any signs of spoilage are there, don’t risk your health and quickly get rid of it.
