Try this when you’re feeling froggy…
Next time you buy a gallon of milk, pour it off into a couple of clean 2-liter 7-up bottles (or other soda bottles). Cap it & carbonate it slightly - very slightly, just to stiffen it a bit to the touch. You don’t wanna taste the carbonation in a glass of milk.
Why? Well, it extends the shelf life. I’ve kept milk up to 90-days in the fridge with this technique. Since most brew guyz have access to carbonating tools, this should be EZ4U. Enjoy.
