Serving contextA slice often weighs about 35–60 g; bakery cuts vary widely.A commercial-style slice is often about 25–45 g; artisan slices may be larger.
How to chooseLook for a well-baked crust and a crumb suited to your use: tighter for sandwiches, more open for dipping and toast.Check whether whole-wheat flour is the main flour. “Wheat bread” alone does not necessarily mean 100% whole wheat.
StorageKeep cut-side down or wrapped at room temperature for short storage. Freeze sliced bread for longer storage.Keep sealed to limit drying; freeze extra slices if the loaf will not be used soon.
How to choose
Choose by flour composition and intended use—not by a health halo. A sourdough can be white-flour based; a whole-wheat loaf can use yeast or sourdough fermentation.
