I keep my beans in the freezer..
I don’t think that retains the freshness and dries them out, but that’s my opinion.
When I was buying regular store coffee, I’d get a $1.00 off coupon and ALWAYS buy the smallest size and you’d drink it before it would go bad.
I suggest coffeemaker with a thermal carafe, I think ours is MrCoffee, it keeps the coffee warm but shuts off so it doesn't continue to "cook".
Also, because I have tasted Starbucks new "cold brew" and it's dramatically smoother than their regular iced coffee, I bought this little gizmo
on Amazon. Makes perfect, smooth iced coffee overnight. Same concept as "sun tea."
