Gluten-free bread is often lovely on the day it is baked, dry the next day and mouldy on the third. It is not your imagination, and there is nothing wrong with your baking either: gluten-free bread simply behaves differently from wheat bread. Here is why, and how to store it so you get as many good slices as possible out of every loaf.
Why gluten-free bread behaves differently
Ordinary bread is held together by gluten, an elastic network that traps moisture and keeps the crumb soft and intact. Gluten-free dough lacks that network, and compensates with more liquid and binders such as psyllium husk and various starches. The result is a loaf with a higher moisture content and a looser structure.
Those two properties pull in opposite directions: the extra moisture makes the bread more prone to mould, while the starch that lacks gluten support crystallises faster, so the crumb dries out and crumbles. Gluten-free bread loses the battle at both ends, and the way you store it has to allow for both.
This is also why shop-bought gluten-free bread often contains preservatives and moisture-retaining additives: the manufacturers are fighting the same two processes. At home you do not have those aids, so the storage has to do the whole job.
More moisture means faster mould
Because gluten-free dough is baked wetter, the loaf gives off more moisture in the days after baking. Put it in a sealed plastic bag and all that moisture sits as condensation on the inside, and you have built a greenhouse for mould. Where a wheat loaf typically shows its first spots after 2 to 3 days in plastic, a gluten-free loaf can get going even earlier.
The mechanism is the same as for everything home-baked: moisture plus still air is all mould needs. We have explained the whole process in the article on why home-baked bread goes mouldy.
The fridge: tempting, but wrong
Many people put gluten-free bread in the fridge precisely to avoid mould, and it works: the mould is slowed down. The problem is that fridge temperature is where starch crystallises fastest of all. The bread turns dry, hard and tasteless in one day, instead of three.
For gluten-free bread, which already dries out faster than other bread, this is a particularly expensive mistake. The full explanation is in the article on bread in the fridge. The conclusion is the same here: the counter or the freezer, never the fridge.
A breathable bag on the counter: the best everyday solution
Gluten-free bread needs storage that lets the extra moisture escape without leaving the crumb to dry out freely. A bag of beeswax-lined cotton and linen does exactly that: the fabric breathes, so condensation never builds up, while the wax layer slows the drying. The Vokshus Bivoks™ bread bag closes with a clip and is roomy enough for both tin loaves and round loaves.
Ordinary wheat bread stays fresh for 7 to 10 days in the bag. Gluten-free bread has a shorter natural life whatever the storage, so expect 2 to 4 good days on the counter, but that is still a completely different experience from the plastic bag's soft crust and early mould spots.
Freeze the rest the same day, in slices
The single most important habit for gluten-free bread is to freeze whatever you will not manage to eat, the same day the bread is baked or bought. That way you freeze the loaf at its best, instead of freezing a loaf that has already started to dry out.
Slice the bread first, and feel free to lay a small piece of baking paper between the slices, so you can take out exactly as many as you need. The slices go straight from freezer to toaster and taste freshly baked. The whole method, with cooling, wrapping and thawing, is in the guide on freezing bread properly.
Do label the bag with the date. Gluten-free bread keeps its quality for roughly 2 to 3 months in the freezer: it is safe for longer than that, but flavour and texture gradually fade beyond it.
How to rescue a loaf that has already dried out
If the damage is done, all is not lost. Dampen the crust lightly with water and give the loaf a few minutes in a warm oven, and some of the softness returns, or toast the slices and serve them warm. You will find more techniques in the article on reviving dry bread. But the best rescue is, as always, to store it properly from day one.
Frequently asked questions
How long does gluten-free bread keep on the counter?
Expect 2 to 4 good days in a breathable bag at room temperature. In a sealed plastic bag things tend to go wrong sooner, because the extra moisture in the bread turns into condensation and brings mould.
Why does gluten-free bread go mouldy so fast?
Gluten-free dough is baked with more liquid, so the bread contains more moisture than wheat bread. In a sealed bag the moisture turns into condensation, and the mould gets perfect conditions.
Does it help to keep gluten-free bread in the fridge?
No. The fridge slows the mould, but makes the starch crystallise faster, so the bread turns dry and hard in record time. Use the counter for what you will eat soon, and the freezer for the rest.
Can I freeze gluten-free bread twice?
It is not recommended. Every round of freezing and thawing costs moisture, and gluten-free bread has little to spare. Freeze it in slices, and you only thaw what you are actually going to eat.
Give your gluten-free bread better days
The Vokshus Bivoks™ bread bag in cotton and linen breathes out the extra moisture and slows the drying, exactly what gluten-free bread needs on the counter.
