If you’re talking about milk going sour too quickly, a few simple habits can help extend its freshness:
- Keep it cold: Store milk at 4°C/40°F or below, preferably toward the back of the refrigerator rather than in the warmer door shelves. (fda.gov)
- Put it back immediately: Don’t leave milk sitting on the counter for extended periods. Perishable foods shouldn’t remain at room temperature for more than 2 hours (or 1 hour when temperatures are above 32°C/90°F). (usda.gov)
- Keep the container closed: This reduces contamination and absorption of odors.
- Don’t drink directly from the carton: It can introduce bacteria.
- Check your refrigerator temperature: An inexpensive refrigerator thermometer can confirm that it stays at or below 4°C/40°F.
🥛 Can you freeze milk?
Yes. If you won’t use it before its use-by date, freezing can prevent waste. Leave some space in the container because milk expands when frozen. Thaw it in the refrigerator and shake it well afterward; the texture may become slightly separated, but it remains useful for cooking or drinking if it was frozen while fresh. (fda.gov)
