La Grameria is the perfect little spot in Colonia Del Valle to buy spices, nuts, herbs, candies & more in bulk. It's a small store that promotes zero waste and eco shopping. They offer a selection of jars and encourage you to bring in your own bulk bags. The owner tries to source products that use organic methods even if they do not have the organic certification, all items are fresh and quality controlled. A great go-to place for various bulk items.
Tip: Try the chocolate amaranth bars. they are delicious. I've never seen these before moving to Mexico, and now I'm addicted. I was so happy to find them in bulk.
