Storing Green Coffee Beans
I was wondering if anybody can give me a suggestion on storing green coffee beans. I currently have them in a cotton sack in a cupboard. My wife HATES the smell. Is it ok to store them in zip lock bags or air tight plastic containers for short periods of time? The temperature and humidity in the cupboard are relatively constant.
I have about 4Kg left and expect this to be consumed with in 8 weeks.
If you use the CS search function ( top right of page header) you will find plenty on the subject.
Storing them in airtight containers in a cool, dark(ish) place will be fine.
In my opinion airtight containers are less than ideal, an ideal environment for promoting the growth of mould, I suspect this is the reason most bulk beans are stored in hessian bags.
Nah, I and plenty of others have been storing greens in airtight for ages. And not small amounts.
The OP said about 8 weeks, not a couple of years………..
Hessian or jute is used because it's the cheapest fibre available to any, let alone 3rd world, country and often is a secondary low land industry for
coffee producing countries in support of coffee growing.
Some coffee producing countries also use hemp.
The beans stored in straight hessian are subject to drying out and becoming 'baggy', a common fault.
Mostly, (but not always) it's the cheapest commercial coffee that is still shipped in straight hessian.
Commercial coffee is now commonly packed, shipped and stored in grain pro plastic bags which breathes air out but not in and doesn't allow moisture to pass the membrane.
It's becoming more common to see high grade and CoE (cup of excellence) beans shipped in airtight/moisture proof vacuum sealed bags,
mostly around 15-30 kgs.
The most I've ever had here, stored in airtight buckets, is about 300kgs.
As I have said in the past……….best practice is to turn your beans over so they aren't being stored for more than a year.
When you store in airtight conditions are you also doing this under vacuum? I tend to store my beans in Mason jars... started off being quite diligent and using my Sunbeam Foodsaver vacuum system but recently have been a bit more lazy.
No, it's not a vacuum.
Just food grade plastic 20kg buckets…….. with very tight lids.
Thanks for the replies. Given the small amounts I have and the relatively short period I store it, I will try out good quality air tight containers.
