Trying to get my Christmas gift ideas lined up for this year so I’m not spending dangerous sleepless nights getting them done before the deadline again this year… I roast my own coffee beans and I had the thought I’d make everyone a pound of home-roasted coffee, and maybe a cool reusable container they could keep it in on their counter tops. Two questions for you:

1. Is a wooden food storage container safe? I’m well versed in the debates about cutting boards. I’d probably finish in BLO but that’s undecided right now. I guess my question is more whether it would seal enough to keep coffee beans fresh.

2. I was thinking a simple tall box with a gasketed lid. Kind of like below pic. Is it even possible to buy these gaskets? I’m not a turner so they would have to be square, or wrap around a square lid. Where would I look? The only thing that comes to mind is McMaster Carr, but the site is frankly overwhelming and I only found these food-grade o-rings. (edit: looks like the link doesn’t work. It’s part number 9555K54 – and it’s only 1.5” diameter, would need something around a 16” diameter)

Alibaba has a few options, but minimum order is between 500-50,000 pieces LOL. I need maybe 10.

Why not just make a friction fit box? A nice tight fit should make for as air tight a seal as you’ll get with wood. As for finish, I’d only do the outside of the box. Leave the inside alone and it’ll likely absorb some of the oils from the beans and eventually develop a nice “patina” of freshly roasted coffee beans.

I guess I don’t trust myself to make something so tight.

Good idea just finishing the outside.

Do not use BLO for food contact, the dryers in it are toxic. If finishing at all go with a salad bowl finish, which is food safe and good for surfaces which you won’t be using an edged tool on.

While I love BLO, I would never use it for food contact. The smell reminds me of my grandfather, but I would not want it transferred to my coffee.

Thanks for the tips on finishes. What do you think about the lid seal?
