Karlovarský suchar is a rusk, a toasted bread cut in thin slices from a whole load, produced in the Karlovy Vary region in the Czech Republic. There are two varieties of the bread - special and diet versions. The bread is well baked and dried, clean, crisp and uniformly porous.

It is golden brown in color, with a delicate scent of bakery goods. The taste is that of baked bread. Both versions of the bread must contain Karlovy Vary spring water. The special variety is made from wheat flour, spring water, sugar, yeast, salt, egg yolk, and flour improver.

The diet version is made from the same ingredients, but sugar, egg yolks and salt are removed from the mix. When the bread is toasted, it is left to cool and sold in packs of 200 grams, ready to be enjoyed with fruit jams, butter, and tea.
