Review on Airscape Coffee and Food Storage Canister - Airtight Lid for Optimal Freshness, Two-Way Valve, Stainless Steel Container, Small 4-Inch (Mocha Brown) by Alisha Bradley

I use this to store whole roasted coffee beans until I'm ready to grind them. Then every time I use enough beans for the espresso I make. Now I can store beans for many weeks (4, 5 or more) and get a nice crema (i.e. golden froth) over a shot of espresso every time. Wonderful. Before I bought this, I stored the beans right in my MDF coffee grinder, which has a lid, but the lid is just a plastic lid that sits there and doesn't seal at all. When I kept my beans in the grinder I was only able to get crema for the first 2 weeks. So this container is great, although it's a bit more work for me because I can actually use a grinder to store beans.
