Not sure where I came up with this idea or whether it is something that has been done before.
I found that while I wanted to reuse my old coffee bags that once housed that precious fresh roast...
The plastic of those one way valve resealable coffee bags seemed to retain an awful lot of smell, and not always good.
Yes, I cleaned them but they just did not seem as easy to clean as a good old mason jar.
So with the help of a drill bit and a very old Dremel I was able to carve out a nice round hole in the lid of a mason jar.
I cut out the one way valve from the stinky bag and trimmed off any of the remaining plastic bag from the valve.
And with a little glue applied all around the underside lip of the valve pressed it on the lid.
In 24 hours the lid was ready to go on the jar and vent out gasses from the fresh roast.
Some other ideas are: tinted jars and or jar art. Yes, I found jar art for mason jars available on line.
Either of these options could shield those beans from light.
Also, jars are available in a larger size or wide-mouth and lids can be bought separately as well.
Sorry about the pic. That UFO looking disk on top of the jar is the one way valve.
After a few days, for espresso beans you can replace the vented lid with a regular one.
Can you tell I like this idea?
