Keeping Sourdough Fresh
Sourdough stays best at room temperature in a paper bag or a breathable linen cloth for up to three days. If you need it to last longer, slice the loaf and store it in the freezer, toasted directly from frozen to restore its original character.
Control the humidity.
Your primary enemy is condensation, which turns a crisp crust into a soggy mess within hours. Keep the bread away from plastic bags until you are ready to freeze it.

Managing the crust
If the bread feels soft, leave the cut side facing down on a wooden board. This allows the bread to breathe, keeping the crust crackling and the crumb supple.
The method.
Store at room temperature
Place the loaf in a paper bag or wrap it loosely in a tea towel. Keep it on the counter away from direct sunlight or the heat of the oven.
Prevent moisture buildup
Never put a warm loaf into any container; wait until it is cool to the touch. If you see condensation inside the bag, open it to let the trapped steam escape.
Freeze for longevity
Slice the entire loaf once it is cool. Stack the slices or wrap them in airtight plastic. When you want a piece, move it directly from the freezer to the toaster or a hot skillet.
When it doesn't go to plan.
If a loaf starts to stale, dampen the crust with a light mist of water and bake it at 350°F for five minutes to refresh it.
Avoid the refrigerator at all costs; the environment accelerates starch retrogradation, making the bread go stale significantly faster than it would on the counter.
A wooden cutting board is the best place to keep your bread; it regulates moisture naturally.
The ones that keep coming up.
Can I store bread in plastic?
Only if you intend to freeze it. Plastic traps moisture, which ruins the texture of the crust and encourages mold growth.
How do I know if it has gone bad?
Sourdough is prone to mold if kept in a humid environment. If you see fuzz or notice an off-smell, the loaf should be discarded.
