Recently switched to black coffee for a few weeks. I’ve had sour, bitter notes from the office coffee machine and a chain cafe.
I’ve also had salty aftertastes from Starbucks and a small one person run shop.
Basically I have no idea what good black coffee taste like.
Just trying to do intermittent fasting and have no calories in the morning, any tips?
Salty in espresso means underextracted coffee. Many factors play there: such as grind size, pull time, tamping method, and water temp. A good espresso taste balance, you got the acidity and bitterness in sync, and give you sweet creamy taste.
Note: pourover methods usually more forgiving and give you better taste. I suggest you try those methods for your black coffee.
