The quality of ingredients that goes into each bottle is what sets Winchester apart from all other coffee inspired e-juices. We start with certified organic Peruvian coffee beans that are decaffeinated using the Swiss Water process, which is done in small batches without the use of chemicals. We than use 100% American USP Vegetable Glycerin to start naturally extracting the coffee flavoring. That creates the base of our flavor and why we refer to it as a premium coffee flavored E-juice. With a light creamy finish, it's sure to appeal to all coffee lovers.
