I've been buying from Penzeys for a long time. I started with the jars of spices and now buy bulk
once a year when I run out of something. I have a large herb garden, but many herbs are not available in winter.
I love their Cumin, cinnamon, Sarawak White Peppercorns, 4 peppercorn blend, Chipotle, Ancho, and Adobo chili powders, Thyme, Rosemary, Tarragon......oh heck, I love it all. I have never purchased anything from them that I did not use up. I love the samples because it exposes me to new blends. The bulk products come in heavy plastic. After opening I put into a large freezer bag with other varietes inside, push out the air and seal. It all stays fresh for one year and longer.
