Here's a great, reusable alternative to plastic valve bags. It offers the same level of protection for your fresh roasted batch of coffee. It's a 12 oz. coffee tin with a de-gas valve on the bottom. Light roasts might fit nearly 1 pound whereas darker roasts will squeak by with 12 ounces, so we consider it a 12 oz. tin.
It seals quite nicely with the white flexible plastic insert, forcing CO2 from fresh coffee to exit from the valve on the bottom. CO2 will push out O2 in the process, so if you fill this tin promptly after roasting you should have an oxygen-free environment for your coffee ... well, until you open it.
We like this tin because it is plain, ready for you to customize and reusable. One important detail to note: this tin should not be washed with water! The valve has a paper filament and won't function if it gets wet. You should be able to clean off any residual coffee oils with a dry towel and continually refill it.
