Pistachios are expensive for several reasons. In addition to the obvious needs (such as enough water and fertile land in the right climate for trees to grow), pistachios require a great deal of labor to harvest them. Of course, labor is also a costly expense for pistachio producers. The first reason pistachios are among the most expensive nuts is that they require special weather conditions to grow.
Why are pistachios so expensive? Because it takes a lot of pistachios to make a single bag, they're expensive. It takes about 12,000 raw pistachios to create 1 pound of shelled walnuts. If it makes you sad to know why those pistachios cost so much and why shelled pistachios are so expensive, you can always opt for unshelled pistachios. Growing and cultivating pistachios is a very challenging endeavor that makes it difficult to meet the high demand for pistachios, and that is why the price is so high that it places them among the most expensive nuts.
