COFFEEVAC 1/2 LB – Patented Airtight Container | Multi-use Vacuum container works as smell proof containers for ground coffee and coffee bean containers. Black cap and body

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.

I recently got back into grinding my own coffee beans and maintaining the work of a French press, and I have three other TightVac containers. This is an appropriate fit for a 12 oz bag of beans, but I find it best to store half the bag at a time and freeze the other. I believe the container fits just about the whole bag to its brim-- but the container maintains peak freshness for about two weeks, and it takes me about three and a half weeks to go through a bag of beans with daily use. Maintaining freshness is all about keeping smaller quantities. About the container itself: It's a sturdy plastic, vacuum seal at the press of an innovative valve button. Stands at a little over 5" tall and is 4" diameter. The opaque black color keeps light out completely to maintain freshness. These are worth investing in for food storage.

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.

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.

These are cheap and do a good job of storing the roughly half-pound of coffee I roast about once a week. Over time, the cap gets harder and harder to remove/put-on because the container might slightly warp out of round. It used to be super smooth to get the cap on and off, but it's a little harder now after using them for about a year. I might try a little bit of lube to make it slip on more easily.

Me encanta como mi café nunca pierde su aroma en este contenedor .

I've used this now for five months and its super! I grind enough coffee beans to fill this cannister and it keeps them fresh with the vacuum seal process. I have arthritis in my hands but I am able to manage this- the lid does slide off but is tight and I appreciate it, as it has a good seal. These would be great to use for storing dry goods for camping or an RV - your coffee, sugar, flour would stay fresh and it has a very tight seal. Great product. Good price and came packaged well when it was delivered. I'm single, so I don't have much to store in my pantry but in the days when I had a large family- I would have needed many of these.

I’ve had my little coffee keeper for years. Filling it with freshly ground coffee and opening it two to three times a day for a cuppa. This morning I noticed a small crack in the top and thought it might be time to replace it. Imagine my surprise when I see that I bought it 10 years ago! That means I’ve opened and closed the lid10;000 times — and it’s just now showing its age, I’d say that was super value! And total satisfaction.

The mechanism of the container is airtight as designed.

Top product!

Funziona molto bene. Vediamo se alla lunga fa ancora il suo dovere.

El café lleva una semana y cada vez que abro el bote es como si abriera una bolsa de café nueva. Perfecto.

Conserva bien elcafe
