2 weeks and beans start to die and get crappy, store it in a dark airtight container. if you want a high quality coffee get some beanz freshly roasted within the past week, and use it within a week. keep em whole and grind em as you use em. obviously thats best if you drink a lot or buy in smaller amounts
ill second the one cup a day, and the coffee for taste. that being said this morning and most mornings im drinking cuban style espresso out of a moka pot from pilon pre ground espresso. because im a lazy piece of shit.
if im not feeling so lazy tarrazzu at trader joes is good in a FP, stumptown is better. dont let them sell you a single origin for 2.5x the price, they all taste the same (at least to my pallette). when im feeling extra saucy ill use that for bulletproof coffee but thats really just a wintertime thing
