Yeah but Bruce, what if BPA leeches onto me kernels
Personally, I just use ziplock freezer bags for large quantities of beans (ie more than 350g around the holidays etc). Even then, I find it better to double bag. The rest of the time, I reuse old bags. Anybody got any research on the effects of degassing in a CO2 rich environment as opposed to in open air?
This is an interesting article on the topic of freshness, even if it leaves lots of questions un-answered:
Defining Freshness.
In the end, probably the easiest solution is just to invite Bruce round and drink it before it goes stale! Bruce, how long do you think it'll take you to get here?
