Hello, so need some help on keeping whole beans fresher longer. My bro works at starbucks so that's what I drink cause free works for me. I grind the beans fresh every time but I notice that when i get towards the end of the bag coffee just doesn't taste as fresh. Takes me about 2 - 2 1/2 weeks to get through the 1lb bag which to my understanding is about as long as beans maintain peak freshness. I currently just keep the beans in the starbucks bag, folded up trying to get as much air out as I can. Searching on the internet i came across this Airscape Canister. would it help keep beans fresher longer? Is there a better solution? I was thinking about grinding some to use at work (to finish the bag quicker) but i know ground coffee "goes bad" faster. I have some containers that i store my tea in Tea Tin would it keep ground coffee fresh for 3-4 days?
