You could taste the pasture. Associated with using excessively high temperatures in pasteurization of cream with developed acidity, prolonged holding times in forewarming vats or when using vat pasteurization. For this phase to occur at any meaningful rate, some type of oxidative initiators must also be present, such as chemical oxidizers, transition metals (i.e., iron or copper), or enzymes (i.e., lipoxygenases).

Associated with extended holding periods of butter for several months or longer. It often occurs if the membranes around milkfat globules are weakened or broken. In complex systems, the products of each of these phases will increase and decrease over time, making it difficult to quantitatively measure lipid oxidation. Oh, and lets not forget using it for dunking bread sticks and pretzels! Butter would taste different if the cow was eating feed (alfalfa, sweet clover) or weeds (onion grass, dandelions). My guess is: 1. soapy, baby-vomit, blue cheese). However, in butter fat (and coconut oil), low levels of shorter carbon chain fatty acids may be quite objectionable. Something I also like to do with it is incorporate it into a blue cheese compound butter. Silage flavor may vary in degree and character depending on the time of feeding, extent of fermentation and kind of silage. During the initiation phase, molecular oxygen combines with unsaturated fatty acids to produce hydroperoxides and free radicals, both of which are very reactive. I remember refusing to eat it because it smelled like cheese. Today, most cows eat pretty standardized diets, but the smell of the barn will affect flavors, as does the amount of time since the cows last ate.

Attributable to the action of certain microorganisms or enzymes in the cream before churning, certain types of feeds and late lactation. Attributable to excessive washing of the butter or to a low percentage of fats or volatile acids and other volatile products that help to produce a pleasing butter flavor. The worst offender being butyric acid (butanoic acid). You may unsubscribe at any time. You must lose all Gluten, and you MUST be very strict about this.

Rancid butter becomes yellow to brown and the flavor becomes harsh. They called it "raw butter", meaning it hadn't gone through processing. Associated with using high temperatures in pasteurization of cream with slight acid development. The processes are generally considered to occur in three phases: an initiation or induction phase, a propagation phase, and a termination phase.
