What is the shelf life of homemade butter in summer?

Question

How long does homemade butter last during the hot summer months? Discover the best way to store it to extend its shelf life and prevent rancidity.

Answer 1

Homemade butter typically lasts for about 1-2 weeks in the refrigerator during the summer months, provided it's stored properly. The warmer temperatures can accelerate spoilage.

Detailed Explanation:

The shelf life of homemade butter in the summer is shorter than in cooler months due to the increased risk of bacterial growth. Several factors influence how long your butter will stay fresh:

1. Purity of Ingredients: Using high-quality, pasteurized cream is crucial. Raw cream can introduce bacteria that shorten the butter's lifespan.

2. Salt Content: Salt acts as a preservative. Salted butter will generally last longer than unsalted butter. Adding about 1/4 to 1/2 teaspoon of salt per cup of cream can help extend its shelf life.

3. Water Content: Thoroughly rinsing the butter after churning is essential to remove buttermilk, which contains lactose and proteins that can spoil. The less water remaining in the butter, the longer it will last.

4. Storage Conditions: Store the butter in an airtight container in the coldest part of your refrigerator, ideally towards the back. Avoid storing it in the refrigerator door, where temperatures fluctuate more.

5. Temperature: Summer heat can affect the butter even inside the refrigerator. Keeping your refrigerator at a consistent temperature of 40°F (4°C) or below is vital.

Look for signs of spoilage such as a rancid smell, discoloration, or a slimy texture. If you notice any of these, discard the butter.

Pro Tip:

To extend the shelf life of your homemade butter, consider freezing it. Wrap it tightly in plastic wrap and then place it in a freezer bag. Frozen butter can last for several months without significant loss of quality.
