How long does oat milk last? the secret to keeping your milky goodness fresh

Oat milk has become increasingly popular as a dairy-free alternative, offering a creamy and nutritious beverage. However, like any perishable food, oat milk has a limited shelf life. Understanding how long oat milk keeps is crucial to ensure its freshness and prevent spoilage. This comprehensive guide will delve into the various factors that influence the shelf life of oat milk and provide practical tips for maximizing its lifespan.

Shelf Life of Oat Milk

The shelf life of oat milk varies depending on several factors, including:

• Type of Oat Milk: Commercial oat milk typically has a longer shelf life than homemade oat milk due to added preservatives.
• Packaging: Oat milk sold in shelf-stable Tetra Paks or cartons has a longer shelf life than oat milk sold in refrigerated containers.
• Storage Conditions: Oat milk should be stored in the refrigerator at temperatures between 34°F (1.1°C) and 40°F (4.4°C).

Shelf Life of Opened Oat Milk

Once opened, the shelf life of oat milk is reduced significantly. The following guidelines apply:

• Refrigerated: Opened oat milk in the refrigerator can last for 7-10 days.
• Unopened: Unopened oat milk in the refrigerator can last for up to 14 days beyond its printed expiration date.

Shelf Life of Homemade Oat Milk

Homemade oat milk has a shorter shelf life than commercial oat milk. It should be consumed within 3-4 days when refrigerated properly.

Signs of Spoiled Oat Milk

Spoiled oat milk exhibits several telltale signs, including:

• Sour Smell: A sour or fermented odor indicates spoilage.
• Lumpy Texture: Oat milk that has separated into curds and whey has gone bad.
• Mold Growth: Any visible mold on the surface of the oat milk is a clear sign of spoilage.
