How Long Does Cultured Butter Stay Fresh?
Keep your high-fat spread delicious and safe in the fridge.
Cultured-butter lasts about 1–3 months when kept properly in the refrigerator.
Cultured-butter is a luxurious dairy staple, aged to develop a tangy flavor and rich texture. Because of its high butterfat content and fermentation process, it behaves similarly to standard butter but often has a more complex profile. When stored correctly in the refrigerator, its high fat content acts as a natural preservative, allowing it to stay fresh for several months. However, exposure to air and moisture can eventually lead to oxidation or mold growth. Keeping your cultured-butter tightly wrapped is the best way to maintain that signature tang and creamy consistency.
