Soy milk, rice milk, and now oat milk, the latest (according to my experience of the world) in the line of plant-based milk substitutes. From what I can gather, oat milk has a bit of an edge on the rest.
Oats have been long associated with good heart health for their cholesterol lowering properties. They're also a great source of "good" carbohydrates and pack a decent amount of dietary fiber. All of these wonderful properties are inherent in this milky concoction. It's also rather tasty but, then again, I'm a fan of raw oats. Rather then make oatmeal/porridge and turn the little grains into mush, I prefer to just add some milk to raw rolled or steel cut oats and dig in. Occasionally, for a quick snack, I'll forgo the milk and just toss a handful of the oats into my feed bag.
The distinct oat taste was dominant in this drink and the crisp, clean flavor gave it a grassy overtone. The texture was smooth, and slightly creamy with a very subtle silty feel. I enjoyed it so much that I drank the entire contents of my container over the course of an evening leaving only a couple mouthfuls for the next morning. But the relatively low calorie count meant that this exercise in gluttony wasn't as disastrous as it would have been with a liter of real milk.
I haven't yet seen the stuff for sale in my local supermarkets in the US and I found this one on a recent trip to England. Here's hoping it makes its way to the States so I make this a regular part of my daily overindulgence.
