TightVac 10L - Largest Airtight Bulk Container

The biggest bulk buy only pays off if the last of it is still good.

The TightVac 10L, better known as the BreadVac, is the largest container in the range: about 2.5kg of flour, grains, cereal or a couple of loaves in one sealed container instead of a sack with the top folded over, slowly going stale on the floor of the cupboard. It is one product at this size, so the question is simply whether you buy big enough to fill it.

The decision that matters

At the top of the range the filter is how much you buy at a time, not the model. The 10L holds about 2.5kg, which is a whole sack of flour decanted in one go, a big cereal or grain stash, or a few loaves kept soft. If you buy a kilo at a time, it is more container than you need and the TightVac 3.8L is the sensible pick; if you buy 500g staples, the TightVac 2.35L is enough. The 10L earns its size only when the quantity matches it. Same one-press airlock and 2-way valve as every size below.

Which bulk size do you need?

How much you buy at a time	Capacity	Who it suits	What to buy
Around 500g at a time	~680g	Regular bulk, one or two staples	TightVac 2.35L
A 1kg bag decanted whole	~1kg	Bulk buyers, meal preppers, campers	TightVac 3.8L
A 2.5kg sack, a grain stash, or a few loaves	~2.5kg, largest in the range	Big households, bulk bakers, batch cooks	TightVac 10L (BreadVac)

Short version: a whole 2.5kg sack in one sealed container is exactly what the 10L is for. Buying a kilo, drop to the 3.8L; buying 500g staples, the 2.35L is plenty.

What we carry at this size

BreadVac. The TightVac bulk container at 10L, holding about 2.5kg. A whole sack of flour, grains, cereal, rice or a couple of loaves decanted and kept fresh with the same patented seal as the smaller sizes, in a body sized for the pantry floor or a larder shelf rather than a worktop.

How to choose

There is one container at this size, so the real choice is whether 2.5kg fits how you shop and cook. Buy the 10L if you bake in quantity, batch-cook, or feed a big household and get through a sack before it turns, because this is the size that makes buying by the sack worth it. The honest trade-off is footprint: it is the largest we make, so it needs a cupboard floor or a larder shelf rather than a crowded worktop, and it only does its job if you fill it, since a 10L half full of air keeps no better than a smaller one packed. Bread, flour and grains are what people reach for it most, but it is a bulk dry-goods container at heart rather than a dedicated bread bin, so treat it as the sack-sized end of the TightVac line. Buying less, the TightVac 3.8L is the step down.

Getting it right

Fill it close to the top so there is little air over the contents; that is where the freshness comes from, not the litres. Press the lid until you hear the pfff, and open slowly so flour does not puff into the seal. Keep it off a damp floor and out of direct sun, solid-bodied for anything light fades. For bread, it keeps loaves and rolls softer for longer by holding the air off them; for flour and grains, decant the whole sack and reseal after each use rather than clipping the bag. It is heavy when full, so give it a settled spot rather than moving it about. Hand-wash only and dry fully before refilling, and a sack-sized buy stays fresh up to three times longer than in the bag it came in.

Common questions

How much does the TightVac 10L (BreadVac) hold?

About 2.5kg of dry goods, which is a whole sack of flour decanted, a big grain or cereal stash, or a couple of loaves. If that is more than you buy at a time, the TightVac 3.8L holds about a kilo and the TightVac 2.35L about 680g. Match the size to how much you get through so the container is filled rather than half air, which is what keeps the contents fresh at any size.

Can I store bread in it?

Yes, that is one of the jobs it does well. A couple of loaves or a batch of rolls keep softer for longer because the seal holds the air off them, which is what dries bread out in an open bag or a basket. It is not only for bread, though: the same 10L is just as happy with a sack of flour, grains or cereal, which is why we treat it as the largest bulk container in the range rather than a single-purpose bin. See the smaller sizes at the TightVac containers hub.

Is it good for bulk flour and grains?

Yes, it is the size made for a whole sack. Flour and grains bought in quantity pick up moisture and odours once the bag is opened, and the seal keeps both out so 2.5kg stays dry and loose rather than clumping or turning. Decant the whole sack in one go, press the lid, and reseal after each scoop. Keep it off a damp floor and out of the sun. If a sack is more than you use, the TightVac 3.8L at about a kilo is the step down.

What is the difference between the 2.35L, 3.8L and 10L?

Only capacity; the seal is identical across all three. The TightVac 2.35L holds about 680g for a regular bulk staple, the TightVac 3.8L holds about a kilo for a 1kg bag decanted whole, and the 10L holds about 2.5kg for a whole sack or a few loaves. Buy the one that matches how much you buy at a time, because a container packed close to the top keeps its contents fresher than one half full of air.

Is this a true vacuum seal?

No. It is a strong partial vacuum from a one-button airlock, not a pump motor. One press removes most of the air sitting around your bulk dry goods, which is the part that keeps flour, grains and bread fresh. For sack-sized storage that is all it needs to do, and there is no motor or power involved. If you want a pull-down hand pump, that is on the CoffeeVac 3-in-1 PUMP, a much smaller coffee model. See the full range at the TightVac containers hub.

How do I clean and care for it?

Hand-wash only, with a rinse and a full air-dry before refilling. At this size it matters because flour leaves a fine residue and any damp left in the seal can carry into the next sack. No dishwasher, since heat can warp the lid over time. The seal is a partial vacuum from a one-button airlock, with no motor and nothing fiddly inside, so you are only cleaning the body and the rim. It is heavy when full, so wash it empty. See care notes across the range at the TightVac containers hub.
