How long can I keep open almond milk cartons at room temperature?

Open almond milk cartons last for about 2 hours when left at room temperature. Moreover, if the temperature outside is more than 90 °F, almond milk will last for only about an hour. Almond milk is a perishable commodity and has a lot of macro and micronutrients present in it. Moreover, it has a lot of water present in its formulation so if it is kept out for more than 2 hours, bacteria and other microbes will find their way into your almond milk and will spoil it. 

What is the optimum temperature to store almond milk?

You should always store almond milk at 40°F or below in the fridge. Bacterial growth takes place at a faster pace between the temperature of 40°F and 140°F, therefore it is always advised to store almond milk at a lower temperature to preserve its freshness and quality for a long time.

How can you store almond milk properly?

  1. Almond milk can pick up odors therefore it should be stored in an air-tight container or bottle in the fridge. Moreover, it should be stored away from strong-smelling food items like garlic, onion, etc. 
  2. It is better to store almond milk on a shelf of the refrigerator rather than the door as there is a lot of temperature fluctuation at the door of the fridge and that can harm the quality of almond milk.
  3. Almond milk should be stored on the lowest shelf of the refrigerator as it is the coldest part of the refrigerator and has its temperature between 38 °F to 40 °F.
