A good sourdough loaf is a small work of art on baking day: crackling on the outside, moist on the inside. Two days later it is either dry and crumbly — or the crust has gone soft and leathery and the first mould is sitting on the cut face. That is almost never the bread's fault. It is a question of where the loaf spent the night.
The good news: storing bread properly costs nothing, needs no gadget, and fits into two sentences. You only have to drop two habits.
Mistake 1: The plastic bag
Plastic does not let moisture through — and that is exactly the problem. Bread keeps releasing water vapour for days after baking. Inside a plastic bag that vapour has nowhere to go: it condenses on the inside and creeps back into the crust. The crust you paid for turns soft and chewy.
On top of that comes the warm, damp climate inside the bag. Mould spores are on every loaf — they come from the air, that is normal and no sign of a bad bakery. All they need to get going is moisture, and the bag delivers it. In short: a plastic bag does not keep bread fresh, it keeps bread damp. Those are not the same thing.
Mistake 2: The fridge
The mistake that surprises most people: bread goes stale faster in the fridge, not slower.
Behind this sits a process with an awkward name — retrogradation. During baking, the starch in the dough swells and binds water. Afterwards it slowly contracts again, recrystallises and releases that water: the bread turns dry, hard and crumbly. The process depends on temperature, and it runs fastest just above freezing — which is precisely fridge temperature. A loaf that spent three days in the fridge has typically aged further than one that spent three days on the kitchen counter.
The freezer, on the other hand, is perfectly fine. Deep-frozen, retrogradation essentially comes to a halt — the state of the loaf is frozen in place, quite literally. Rule of thumb: freeze yes, chill no.
What bread actually needs
The crust is the packaging the loaf brings along by itself. It slows down drying and keeps the crumb moist — as long as it stays dry and intact. The moment you cut into the loaf, you have an open wound: water evaporates from the cut face, and that is where the bread starts to age.
Which gives you the whole instruction manual: protect the cut face, let the crust breathe. Whatever you wrap around it should slow the drying down, not lock the moisture in. That is why something slightly permeable beats something completely sealed.
How to store your bread
- Cut face down. Stand the loaf on a clean wooden board, cut side down. It is the simplest and most effective trick there is: the bread seals its own wound while the crust stays up in the air.
- Cover loosely instead of wrapping airtight. A cotton or linen cloth, a bread box with air holes, a wax wrap around the cut end — all fine. The point is that the crust must not sit in its own steam.
- Room temperature. Not on a sunny windowsill and not right next to the oven or a radiator, but otherwise a normal spot in the kitchen is exactly right.
- Wipe out the bread box regularly — vinegar and water work well — and let it dry completely. Last week's crumbs are the mould source for tomorrow's loaf. This is the most commonly overlooked point of all.
- Whatever you will not eat within a few days, freeze straight away. Ideally in slices: then you take out only what you need and can toast it directly from frozen. The important word is straight away — freezing preserves the state of the bread, it does not repair it. A half-dry loaf thaws back into a half-dry loaf.
How long does bread keep?
That is decided less by the storage than by the dough. Rough figures from bakeries and kitchens — not laboratory values, and your loaf is allowed to differ:
- Rye and rye-mix bread with sourdough: keeps longest, often the best part of a week. Sourdough lowers the pH of the loaf through lactic and acetic acid, and mould has a harder time in that acidic environment. Sourdough is not only a matter of taste — it is the oldest preservation method in bread culture.
- Wheat-mix bread: roughly three to four days.
- White wheat bread, baguette, ciabatta: one day. A baguette in the evening is no longer what it was in the morning. That is not a defect, that is the dough — little acid, thin crust, a lot of surface.
So claims like "stays fresh for three to seven days", which you often read around bread bags, deserve a closer look. For a rye sourdough loaf that is about right. For a baguette it is simply wrong. Anyone quoting a single number for "bread" has forgotten to ask the dough.
So what do you keep it in?
Cotton and linen are the classic answer: they let air through, slow the drying down and replace the plastic bag without ruining the crust. A wooden or ceramic bread box does the same job.
A beeswax wrap is cotton with a layer of beeswax on it. That makes it less permeable than plain linen, but nowhere near as sealed as cling film — and that is what makes it useful for the cut face. You fold it around the cut end and press it down briefly with your palms (the warmth of your hands makes the wax pliable, so it holds its shape), and the crust stays outside in the air. Exactly the division of labour described above.
Our Beeswax Wrap XXL is the largest in the range at 40 × 50 cm — big enough to wrap a whole farmhouse loaf or to close off the cut side of a long one. If you would rather have a bag than a wrap: our beeswax bags come in three sizes, and the large one takes a whole loaf at 31 × 31 × 9.5 cm. It works on the same principle as the wrap — cotton with a wax coating, breathable rather than sealed — but it is already sewn into shape. A sewn linen bag with no wax at all is a different thing again; we do not carry that.
And because it belongs in the picture, the limits too: wax wraps do not like hot water — the wax melts. They are not for raw meat or raw fish. Rinse cold, let dry, done. Everything else is in the beeswax wrap care guide.
The essentials in three sentences
No plastic bag, no fridge. Cut face down on a board, crust in the air, loosely covered at room temperature. And whatever will not be eaten in the next few days goes into the freezer in slices — then in four weeks' time you will still have today's bread.
