Multi-Use Vacuum Seal Portable Storage airtight Container, 1/2-Pound, Green Tint

I bought my Coffeevac in 2015 and am still using it. It was inexpensive and very easy to use. I chose the black Coffeevac to prevent loss of flavor from exposure to light, and I think that makes a difference.The seal of the lid is still tight after 8 years, but there is one downside. The plastic is rather thin, so it has split around the sides in a few places. I wrapped the outside of the lid with clear packing tape to keep it airtight, and although it still works flawlessly, it's a little disappointing that I had to do that. Having said that, I'll eventually buy another Coffeevac because I haven't seen any better alternatives in that price range.There have been a few reviews that mention how long you can store coffee before it becomes stale. Take those numbers with a grain of salt, as there are a lot of variables. Dark, oily roasts, for example, tend to become stale quicker. I cannot comment on how long the Coffeevac will keep coffee fresh, as I roast my own coffee in 1/2-pound batches (using the Fresh Roast SR800 roaster) and then let them rest for 4 days while I consume the previous batch. One could argue I should let the coffee should rest a couple of days longer, but I have found that 4 days of rest is enough for delicious coffee, and it will never go stale if kept in the Coffeevac and consumed within a week.

Electric vacuum pump canisters are a waste of time and money for storing coffee. Freshly roasted coffee releases carbon dioxide as it rests (this is why coffee bags always have that valve in them) which naturally inhibits oxidation as long as the container is airtight enough to hold the CO2 inside. These containers provide an excellent seal and block out light which is all that you need to properly store your precious beans.

I've already got six Tightvacs and am buying four more today. They do a good job of slowing the staling rate for very fresh whole beans.Some of the people posting on this product do not understand what the term "vacuum seal" means in this context. It neither means nor implies that there is a perfect or near-perfect vacuum in the canister. Rather, if you try to raise the lid of a properly closed Tightvac without opening the valve, you increase the volume of the canister without allowing air to enter, that lowers the pressure in the canister (PV = NRT), making it impossible to remove the lid accidentally. Thus, no new air gets in unintentionally.In terms of slowing the aging/staling process, coffee stored in a Tightvac which would otherwise take five days to age and fifteen to stale, takes about ten to age and thirty to stale. In other words, a Tightvac works very slightly better than a can or heat-sealed bag with a one-way valve.The more completely filled the Tightvac, and the less frequently opened and closed, the better it works. I store my fresh roasts in the one pound size Tightvacs, use about half a canister to fill my grinder hoppers or for blending, then switch the remaining beans to a half pound size canister.They can be stored in the refrigerator or freezer as well as at room temperature. The combination of Tightvac and freezing stops staling dead for months.If you're using pre-ground coffee, the freshness battle is already lost. In that case, a Tightvac won't be any better than any other sealed storage -- a Mason jar for instance.But for anyone who wants to store freshly roasted whole beans, particularly for someone who roasts, these things are gold. And for someone who stores a lot of freshly roasted whole beans with the intention to post-roast blend, they're diamond encrusted platinum.

This is a nice bargain for the price point. It's well made from a thick plastic, operates easily with only one moving part, and cleans up easily with soapy water.A partial vacuum is created when you push the top down onto the canister and most of the air is expelled automatically as you depress a small button on the lid.This size easily holds 1/2 pound of coffee, ground or whole bean.The only reason thing I would change if I could is that the manufacturer should have had the foresight in the design stage to make these stackable, so you could have your sugar container (and whatever else you want to stack up on your shelf or counter) neatly stacked with your coffee. I mean they will stack but not snug into each other so they don't slide around or knock over too easily.I did pack this in a travel bag the other day for a weekend trip to the beach. Had no problem with it staying securely closed either.If that last point doesn't matter for you then it's a 5 star review!! BTW - I paid full price so you can know this is an unbiased review.

Love how fresh my coffee is in this coffee vac

Parfait contient un pot de café très jolie sur le comptoir.

I already have the larger version of this and I'm very happy with it. So when I wanted another smaller one for the office, I went back to the same brand and got this one. Same quality as my previous one and it works great.I'm not sure why people say it doesn't create a vacuum, because it certainly does. They are either expecting some kind of electric pump to suck ALL the air out, or they just don't know what a vacuum is. Honestly, ignore their reviews.I store it in the refrigerator and it has kept my coffee tasting fresh. If that's something you want then buy it.

Excellent . I fill up with 250 gms and leave in the Fridge. Did have to make the grinds (Happy Donkey Italian blend). finer i use a Iberital Grinder. Some one did say about the label. I took mine off as well. But had no trouble. Boiling water for a few secs. Then some Alcohol on a cloth. Then a slight polish with 3M car polish. But maybe getting too fussy but it does look nice. I think. Bob. Enjoy.

Product keeps coffee (or tea) fresh, lid works well, vacuum seals easily. But after receiving it, I feel I paid too much. Still, we use it every day

It was supposed to be the 1lb jar but they sent me the 1/2 lb instead. We liked it and kept it
