Spices have been an essential part of life since the dawn of man. They didn't have the advantage of using a spice rack so their kitchens were rather messy. For centuries spices have been used for many purposes including medicine, religious ceremonies, cosmetics or eaten as a vegetable (garlic for example).
Spices are often very colorful and when they're displayed in kitchen spice racks, they can add color to the room. The use of a wall spice rack frees up needed counter space and are easily accessible. Not only are the spices sealed from humidity, it keeps the flavors from blending into each other.
Turmeric can be used as a preservative and liquorice as a medicine. Some spices kill harmful bacteria or prevent their growth. To get the full value and flavor from your spices, why not think about adding spice racks to your kitchen?
