Named for the river valley in Washington State in which it is grown, Peppermint Oil Yakima is steam-distilled from the Mentha piperita herb and is one of the most common grades of peppermint oil produced in the United States. Peppermint was originally introduced to the US in the early 1800s and the nation is largely responsible for peppermint oil’s prevailing reputation as one of the most popular flavor additives across the world today. The oil’s trademark bitterness is well represented in this variety of mint, though it still retains the fresh green top note and underlying sweetness typical of peppermint. Yakima peppermint oil has a rich, balsamic, and minty-sweet dry down, making it a popular addition to candies, chewing gums, and other common peppermint products.
