Why are there taste differences between different brands of butter?
Several factors are responsible for taste/flavor differences between brands of butter. The cream that is used can have slightly different pH and acid values. Different ingredients in the feed that the cows consume can also have an effect on the flavor of the milk. Butterfat level can differ slightly by different manufacturers. In addition, a natural flavor is usually added to unsalted or cultured butter. These milk-derived cultures are added to the cream prior to churning to add desirable flavor and aroma characteristics.
