Most coffee goes stale in the bag. Every time it is opened, oxygen goes in and the roast starts losing the thing that made it taste like coffee. This jar closes that loop. A pump sits in the lid: press it, the air is drawn out of the headspace, and a silicone ring in the rim holds the vacuum. Press the release button and the lid lifts off, so nothing has to be levered. The body is borosilicate glass and straight-walled — hot water or a spell in the fridge will not crack it, and a scoop reaches the corners instead of leaving a ring of grounds on a ledge. Four capacities, because a 500 ml jar and an 1800 ml jar are for different jobs: 500 ml holds roughly 200 g of beans, 900 ml about 300 g, 1200 ml about 400 g, and 1800 ml about 500 g. Three finishes on the same body — black, white, and black with a gold knob on the pump.

Product details
Supplier photographs of the product itself, the parts that decide how it works and the details a specification table cannot show.
01
The seal is a ring, not a thread
A screw lid is only as good as how hard you can turn it. This one seals with a silicone ring that sits in the rim and is compressed by the vacuum itself — the lower the pressure inside, the harder the lid is pulled down onto the ring. The ring is soft enough to take up the tolerance in the glass and stays elastic, which is what stops air creeping back in between uses.
02
A mouth you can actually work with
Straight walls and a wide mouth are not a design detail on a storage jar. A scoop goes in flat, a spoon reaches the bottom corner, and rinsing it out takes one pass instead of a bottle brush. The same shape is why 1800 ml of beans does not jam at the shoulder when you pour them out.
03
What the vacuum actually does
Air is roughly 78% nitrogen and 21% oxygen. Oxygen is the part that stales coffee: it attacks the oils on the surface of the bean, and the roast flattens within days of the bag being opened. Pumping the headspace out leaves very little of it behind, so the beans are not sitting in oxygen between brews — which is the whole point of portioning and sealing rather than clipping the bag shut.

Where it works
Home bar
A 900 ml jar takes a 300 g bag of beans and keeps the grinder hopper empty between brews.
Café
Portion a roast into jars the day it arrives and open one at a time instead of the whole bag.
Retail / shelf
Straight glass and a plain lid take a label well, and customers can see the roast without opening anything.
Questions before you order
How does the vacuum work?
There is a pump in the lid and a silicone ring in the rim. Press the pump and the air is drawn out of the headspace; the ring holds the seal. Press the button in the middle of the pump to release it and the lid lifts off.
How much coffee fits in each size?
The supplier's figures for whole beans: 500 ml about 200 g, 900 ml about 300 g, 1200 ml about 400 g, 1800 ml about 500 g. Ground coffee settles tighter, so expect slightly more.
Can it hold hot liquid?
The body is borosilicate, which the supplier rates for -20 to 150 °C and rapid temperature change. The lid is ABS with a silicone ring, so wash it by hand rather than in a dishwasher.
Is it airtight enough to store for weeks?
The seal is the silicone ring, not a screw thread, and the pump holds the lid down while there is vacuum. That is what keeps oxygen out; it is a storage jar, not a pressure vessel.
What is the minimum order?
One piece. Sizes and finishes can be mixed — the twelve combinations are listed as variants.
A walnut base with eight glass tubes, each holding one dose — weigh and seal on Sunday, take a tube when you brew. Wood caps or one-way valve caps for resting roasts.
