COLD BREW METHODS
Published research says brewing with a French press, espresso machine could be hurting your health. French press and espresso are high in oily compounds (Diterpenes-Cafestol and Kahweol). Drip coffee makers and single serve machines, produce coffee that’s high in acid that may cause stomach upset, stain teeth and damage tooth enamel. It’s possible to cold brew coffee with a French press, however third party lab tests reveal that high levels of Cafestol remain; regardless of whether hot or cold water is used to brew with this method.
