Start with 1 cup (8 oz.) filtered water, just off the boil.

Measure 2 1/2 heaping tablespoons freshly ground Bulletproof® Upgraded™ Coffee beans (approximately 2 rounded tablespoons per 6 oz. water) and brew strong black coffee using your favorite coffee brewing method. (Why this is important)

Pour in 1 teaspoon Bulletproof® Upgraded™ Brain Octane™ or Bulletproof® Upgraded™ MCT Oil (build up to 1-2 tablespoons over several days).

Add 1 tablespoon grass-fed, unsalted butter or ghee (build up to 2 tablespoons or much more over several days).

Mix in a blender for at least 20 seconds until the drink is frothy and looks like a creamy latte without a film of oil on the surface.
