CoffeeVac 1.85L
CoffeeVac 1.85L - 500g Coffee Storage
Buying coffee by the half-kilo is cheaper per cup, and it is also the fastest way to drink stale coffee - because the bag stays open for twice as long. The CoffeeVac 1.85L is the answer to that trade-off. It is an airtight container that pushes the air out rather than sealing it in, so the last scoop of a 500 g bag still tastes like the first.
What the 1.85L is for
Half-kilo bags, subscription drops, and the roaster deal you could not say no to. Two-coffee households keep one for beans and one for a decaf. Small cafes and mobile baristas use this size between service periods, because it holds a working day of coffee without being refilled.
It suits bulk dry goods too - rice, oats, nuts - anything that goes stale or takes on the smell of the cupboard. It is not for liquids, and it is not a substitute for refrigeration on anything that needs it. Coffee itself should stay out of the fridge: cold air carries moisture, and moisture is the one thing worse for beans than oxygen.
Main features
- Patented 2-way valve - pressing the lid pushes air out, and the CO2 from freshly roasted beans vents out on its own without letting oxygen back in.
- Fresh up to 3x longer than conventional airtight storage, because the oxygen is removed rather than shut in with the coffee.
- Holds around 500 g of whole beans - a full half-kilo bag, decanted.
- BPA-free food-grade plastic, made in the USA and shipped from Europe.
- Clear or solid body - solid keeps daylight off the beans, clear lets you see what is left.
- One-handed opening, with no separate lid to put down mid-pour.
The model in this size
CoffeeVac 1.85L - the large standard container, 19 cm tall and 12 cm across. Same patented 2-way valve as every TightVac, sized around a 500 g bag. There is no V variant at this capacity: the extra degassing valve exists for the first 24 to 48 hours after roasting, which is a window that matters most on small, fresh, single-origin bags rather than bulk.
If you are buying beans within days of their roast date, keep a CoffeeVac V 0.8L for the fresh bag and use the 1.85 L for everything resting behind it.
Is 1.85L the right size?
| Size | Holds | Best for |
|---|---|---|
| 0.57 L | ~150 g coffee | Small bags, a second bean you are working through |
| 0.8 L | ~250 g coffee | The standard roaster bag - one household, one grinder |
| 1.85 L | ~500 g coffee | Bulk bags, two-coffee households, cafe service |
| 3.8 L | ~1000 g dry goods | Bulk storage beyond coffee |
Coffee is lighter than flour or sugar, so the jar fills before it reaches its dry-goods weight - the figures above are for coffee. Buying 500 g at a time? The 1.85 L is the one.
Common questions
How much coffee fits in a 1.85L CoffeeVac?
About 500 g of whole beans - a full half-kilo bag. Ground coffee packs denser and you may fit a little more. Leave some headroom rather than filling to the rim; the lid seals more reliably against a container filled to the shoulder.
Does storing coffee in bulk make it go stale faster?
Only if air can get to it. A 500 g bag left folded over loses more than five 100 g bags would, because it sits open for five times as long. Decanting the whole bag into a sealed container the day it arrives is what closes that gap.
Should coffee be stored in an airtight container?
Yes. Oxygen is what turns coffee flat and papery, so keeping air away from it matters more than anything else you can do at home. An airtight lid keeps new air out; a CoffeeVac also removes the air already inside.
Is the CoffeeVac a true vacuum seal?
No. It is a strong partial vacuum, created by a one-button airlock rather than a pump motor. That removes most of the oxygen sitting around your coffee, which is what actually matters over a fortnight.
