1. From what I've heard, the mycotoxin thing is a bit overblown. Joe Rogan had Dave Asprey (Bulletproof Exec) on his podcast and at a later date, Rogan decided to get a friend to test coffees. From those tests, apparently the toxin levels weren't much different between Whole Foods coffee, local roasters, Starbucks, etc. I don't think super value brands like Folgers were included in this though. My recommendation: Buy coffee from a local roaster (see: hipsters) who care about their trade or a quality brand from a retailer like Whole Foods. 2. Grass-fed butter is a little hard to find depending on where you live. I've had the most luck in Whole Foods and Publix (I live in Atlanta). 3. You don't have to but I think you get the best consistency with one. You may have to melt the butter first and mix it in but I'm sure you could do it just fine stirring with a spoon. It saves time for me since I used to make a full breakfast every morning.
