I am a caffeine junkie. Before keto, I had a '4 to 5 cups a day' tea habit, but black tea holds zero appeal for me so I found myself switching to coffee. I have always loved coffee but now it borders on obsession. We have about 4 different coffee machines and are planning to buy a Nespresso machine next month. I started experimenting with different brewing methods and cold brew was my first exploration away from "regular coffee". I was in love the minute I tasted it. I make cold brew about once a week. It makes 3 litres each time and lasts me about 5 days.
