Butter keeps 1–2 months in the fridge and 6–9 months in the freezer, according to USDA's FoodKeeper. Salted butter tends to stay fresh a little longer than unsalted, because salt slows spoilage. Wrap it tightly in the freezer to block odors. Butter can sit out at room temperature for 1–2 days in a covered dish — less in a warm kitchen, where it turns rancid faster.
How to store butter
Refrigerate butter in its original wrap inside a sealed container — butter absorbs odors from anything strong-smelling nearby (onions, fish, cheese). Aim for under 4°C. For everyday spreading, keep a small amount in a covered butter dish at cool room temperature and use it within 1–2 days. Refrigerate the rest. Freeze in 250g portions wrapped twice (parchment + foil or freezer bag) to prevent freezer burn. Thaw in the fridge overnight.
