Why Bread Goes Stale (and How to Slow It)

Bread stales through a process called retrogradation — starch molecules crystallise over time, making the bread firm and dry. This happens fastest in the fridge and slowest in the freezer. The goal is to slow retrogradation while preventing mould.

Room Temperature Storage (Up to 3 Days)

  • Bread box: The best option for room temperature storage. Allows some air circulation (preventing mould) while limiting airflow (slowing staling). Keep it clean — mould spores in the box will spread to fresh bread.
  • Paper bag: Good for artisan loaves with crusty exteriors — the paper allows the crust to breathe and stay crispy. Plastic bags trap moisture and make crusty bread soggy.
  • Cut side down: For sourdough and similar loaves you have sliced from, place the cut side down on a wooden board or plate. The cut surface dries out fastest — contact with the board slows this.
Never store bread in the fridgeThe fridge temperature (around 4°C) is the worst temperature for bread — it is the sweet spot for starch retrogradation, making bread go stale 2–3 times faster than at room temperature. The only exception is in very humid climates where mould is a bigger concern than staling.

Freezing Bread (Up to 3 Months)

  1. 1

    Slice before freezing

    Slice the whole loaf before freezing so you can take out individual slices as needed rather than defrosting the whole thing.

  2. 2

    Wrap tightly and bag

    Wrap sliced bread tightly in cling wrap or place in a zip-lock bag with as much air removed as possible. Freezer burn (dry, white patches) happens when air reaches the bread.

  3. 3

    Toast straight from frozen

    Most bread can go straight from freezer to toaster — no need to thaw first. Add an extra 30–60 seconds to your usual toast time. For thawing without toasting, leave at room temperature for 30–60 minutes.

Reviving stale breadRun stale bread briefly under cold water then bake at 200°C for 8–10 minutes. The moisture steams the interior back to life and the oven re-crisps the crust. Works surprisingly well on day-old to two-day-old bread.

Frequently Asked Questions

Homemade bread typically lasts 2–3 days at room temperature (it has no preservatives unlike commercial bread). Sourdough lasts slightly longer — the acidity from the fermentation process inhibits mould. Freeze anything you will not eat within 2 days.
A wooden or enamel bread box is ideal — it maintains a slightly humid microclimate that slows staling without trapping enough moisture to encourage mould. Linen bread bags also work well for artisan loaves. Plastic bags are fine for sliced commercial bread but soften crusty loaves.
