Real sourdough is alive. Unlike commercial sandwich bread loaded with preservatives, our loaves are made from four ingredients — flour, water, salt, and a touch of starter and yeast where it helps the bake. That's it. Which means how you store it matters more than how you store the supermarket stuff.
The good news: real sourdough naturally lasts longer than commercial bread because the long fermentation drops the dough's pH, slowing mould growth. The bad news: Dubai's humidity is a different challenge. Here's how to handle it.
The first 4 days: keep it on the counter
For the first four to five days, your sourdough should live at room temperature. Cut-side down on a wooden board, or in a cotton or linen bread bag. The crust will stay crisp, and the crumb will stay soft.
What you must not do: seal it in plastic. Plastic traps moisture, especially in Dubai humidity, and turns your beautiful crust into something rubbery within 12 hours. A paper bag is fine. A cloth bag is better. A plastic bag is the enemy.
If you can, leave the loaf intact and only slice as you go. A whole, uncut loaf retains moisture far better than a pre-sliced one — every cut is another surface for moisture to escape.
Days 5–7: into the fridge — but with a caveat
By day five, even sourdough starts to dry out at room temperature. This is when the fridge becomes useful — but only if you want to revive it before eating.
Wrap the loaf (or sliced portion) in a clean tea towel, then put it in a paper bag or loose plastic bag inside the fridge. The cold slows everything down and buys you another two to three days. Just know: bread tastes better at room temp. Pull a slice 10 minutes before eating, or briefly warm it in the oven (180°C for 4 minutes) to revive the crust.
Beyond a week: freeze it
If you know you won't finish a loaf in seven days, freeze it. This is what we'd actually recommend for any sourdough you're saving for later.
Slice the entire loaf first. Stack the slices, wrap them tightly in baking paper, then put them in a freezer bag with the air pressed out. Frozen sourdough keeps for up to two months without losing flavour.
To eat: pull out a slice or two, drop them straight into a toaster or hot oven. No defrosting needed. The crust crisps up, the crumb softens, and you'd struggle to tell the difference from a fresh slice.
What about the air conditioning?
One Dubai-specific note: if your AC is blasting at 19°C all day, your bread will dry out faster than it would in a milder climate. The cold air pulls moisture out. Keep the loaf in a cloth bag or a covered bread bin to slow that down — and keep it away from direct AC vents.
Quick reference
- Counter, in cloth or paper bag: 4–5 days
- Fridge, wrapped: up to a week (revive before eating)
- Freezer, sliced and wrapped: up to 2 months
- Avoid: plastic bags at room temp, slicing the whole loaf in advance, leaving it cut-side up
If your sourdough goes hard before you've finished it, don't throw it away. Cut it into cubes, drizzle with olive oil and salt, and bake at 180°C for 10 minutes. Best croutons you'll ever make.
