A good sourdough loaf is a small miracle — crusty outside, soft inside, and slow-fermented for flavour. But once you get it home, the clock starts ticking. Here is how we keep ours tasting its best.
Room temperature: the first few days
Sourdough's natural acidity helps it stay fresh longer than regular bread. Research in the journal Foods (2021) found that mixed-type sourdough showed no visible mold until day 10 when stored in a plastic bag at room temperature, and staled more slowly than conventional loaves thanks to slower amylopectin recrystallisation PMC / Foods journal.
For the first two to three days, keep your loaf cut-side down on a wooden board or inside a paper bag. This protects the crumb while letting the crust breathe. Avoid sealing it in plastic too early — trapped moisture softens the crust.
The fridge: not your friend
It feels logical, but refrigeration actually speeds up staling. The same 2021 study showed that sourdough stored in the fridge became 68% more stale than an identical loaf left on the counter in a bag PMC / Foods journal. Cold temperatures accelerate starch retrogradation, so we only recommend the fridge if you are in a very humid environment and need to slow mold — and even then, expect a firmer crumb.
The freezer: your best long-term bet
For anything beyond three or four days, slice and freeze. The USDA FSIS confirms that food kept constantly at 0°F (-18°C) or lower stays safe indefinitely, and freezing halts the staling process. For best quality, aim to use frozen bread within three months University of Nebraska-Lincoln.
Quick tips
- Keep sourdough at room temperature for 2–3 days, cut-side down
- Avoid the fridge — it makes bread stale faster
- Slice and freeze for longer storage; toast straight from frozen
