A turntable, such as this Copco 2555-0187 Non-Skid 2-Tier Cabinet Turntable, 12-Inch helps keep spices organized and easily accessible. You could also opt for a lazy susan, though a smaller tiered version can save space and can fit better in most cupboards.
I love these Prodyne ST-606 Spice Tower Self Stacking Spice-Bottles, Set of 6 that are perfect for organizing cabinets more efficiently.
If you love the modern sleek look, try a product like the Acrylic Spice Rack, Suits Every Kitchen Style, “Invisible” Wall Mount Floating Shelves – 3 Shelf Set which allows you more shelf space while offering a nice clean look.
One of my favorite products are these Kamenstein Magnetic Storage Tins/spice Racks, Set of 3, (4 Packs, 12 units) which can be housed off the shelves. They look amazing too!
Keeping spices in a uniform container can make your cabinets appear super organized. These containers by ChefLand 12-pack Glass Spice Jars with Shaker Top and Red Cap – Classic Square Bottles Design for Storing and Dispensing Spices – Height: 4.1″ Base Width: 1.56″ work well for those who like the traditional look and strive to maintain simplicity.
