i actually view this as a very serious thread as I am also someone who have higher expectation when comes to food related items.
I am still very noob in coffee knowledge, so i need more clarification from u on what do u mean by "fresh".
mine definition is when i hold the beans to my nose, i smell nth.
when i do re-roasting, I heat up the 20cm saucepan, and it has to be very heated up, depends on the quality of the pan, cos mine is thick base, cast iron with a long handle. bring the pan away from the fire, drop 1.5 cups of beans -- measured with the cup i use for measuring rice. immediately, i start to do "flipping" like how chef flip the pasta! same speed as what u see in resturant kitchen, i do that over very low fire for 2-5 mins. when u start to smell the beans behaving like a coffee, remove from fire, and continue to flip away from fire but slower.
cannot place then in bowl cos i dun wan condensation to take place. my first time i did that condensation took place *head bang wall*
which is why say flip slowler and once the heat on beans cool enuff on ur fingers, place them on plate line w cloth or kitchen paper towel.
once i feel they are cool off, i will grind them up.
u ask me if i feel they are recharge, i did the same thing in sg and my current location --a very low humid place. surprisingly to me, both places, the coffe smell return again nicely. but i hv to say not as nice as fresh fresh rah. at least i dun get to grind stale beans and end up give me stale drink.
i personally FEEL it is back to ard 65-70% the last round i did it. cos the beans was out in the " open " for 8 months. I was way too busy during that period but i dun wan to waste my beans T_T. its original full robust is gone. but still can get the nice aroma from a drip/french press. taste wise, abit off but i can finish it, if i dun re-roast it, i will pour away the whole mug.
just becareful dun over roast it. if scare to flip, but wan to learn, can start learning on soya beans or white beans. if ur sense of smell not sensitive. u WILL burn the beans.
BUT pls do share the data with me if u try to do that. i wonder if there's anyone in this thread does the same as me; cos i read that u don't do that to artisan beans. my beans are just the proper cafe grade beans -- > better than starfurk grade
