Elmhurst was originally a dairy brand, founded in 1925 — but a few years back, the owners completely transformed the business into a fully vegan, non-dairy milk company.
For the holidays, Elmhurst makes Oat Nog, which is made of only water, oats, cashews, cane sugar, natural flavors, and salt. It has the simplest ingredient list of all the vegan eggnogs in this article. You can buy it on the website, Amazon, or in some stores.
