Bulletproof InstaMix vs. fatCoffee

In just the last few weeks, Bulletproof has released an “on the go” way to make “butter coffee” instantly. Given the similarity in purported benefits of this new product, dubbed “InstaMix”, I thought it’d be a good idea to try it out, and offer a comparison.

I’m hoping to offer as objective and impartial a comparison as possible, though obviously I have a horse in this race. Bit given the attention that Dave Asprey has brought to butter coffee over the past few years, it seemed inevitable that he would launch a product similar to fatCoffee eventually, and I hope that this comparison is a useful one.

First, to break down some of the basic differences:

Taste ProfileLike powdered Coffeemate Like a foamy, rich vanilla or mocha latte
PortabilityContains butter, but doesn't say if it needs to be refrigerated. Encapsulated in Dextrin, may help with shelf life.Ghee is completely and naturally shelf-stable. fatCoffee requires no refrigeration, and stays fresh for at least a year.
Full IngredientsCaprylic Acid Triglycerides (Brain Octane Oil), Grass-fed Butter, Highly Branched Cyclic Dextrin, Oleic Fatty Acid (from Olive Oil), Sorbitol, Vitamin E TPGS.100% Grass-Fed Organic Ghee, Organic Coconut Oil, MCT Oil, Organic Powdered Goats Milk, Organic Cocoa Butter, Organic Ground Powdered Vanilla Bean

Though the price difference is a bit obscured by the serving sizes, what surprised me most was the fact that InstaMix is almost 2x as expensive per ounce than fatCoffee. Considering the main ingredient is refined MCT oil, I’m not sure what justifies that cost difference. 100% grass-fed butter is our most expensive, and hardest to find, ingredient: MCT oil is plentiful, manufactured by a dozen different companies, and never subject to any supply shortage.

Each serving of InstaMix contains about 1/2 as much mix as a serving of fatCoffee. That comes through in the flavor as well; when mixed with 8oz of coffee, InstaMix has about the same effect on the consistency and flavor of the coffee as a couple of teaspoons of Coffeemate powdered creamer. Calorie and fat content are similarly lopsided.

InstaMix’s ingredients include “grass-fed butter”, though I’ve found that the definition of “grass-fed” is far from standardized, and open to wide interpretation. The ghee in fatCoffee is from butter made from milk from cows that are only ever fed grass, hay, and hayalge. No grains, ever.

Finally, because InstaMix lists “grass-fed butter” as one of its ingredients, I’m uncertain how it can be shelf-stable and travel-ready (though the Bulletproof website claims that it is.) The reason is simple: butter spoils if it’s not either refrigerated, or treated with some type of preservative. I think it’s possible that the “highly branched cyclic dextrin” might act as a preservative, but it also increases the carb count. (Dextrin is a carbohydrate. It can come from a variety of sources, including corn.) Update 7/2/2016: A bit more details on Highly Branched Cyclic Dextrin here.

Have you tried both InstaMix and fatCoffee? How do you think the two compare?
