The strange thing is, coffee does often get branded as acidic, but in reality, a cup of coffee is only around five on the PH scale (1), which makes coffee less acidic than say a can of soda, a beer, or a glass of orange juice. But this is where it gets interesting. Acidity is...
(a) fast roasting green coffee beans comprising from about 50 to 100% high acidity-type coffee beans, from 0 to about 30% low acidity-type coffee beans and from 0 to about 50 moderate acidity-type coffee beans that have not been predried, or only partially predried, to a Hunter L-col...

The acidity and antioxidant activity of cold brew coffee were investigated using light roast coffees from Brazil, two regions of Ethiopia, Columbia, Myanmar, and Mexico. The concentrations of three caffeoylquinic acid (CQA) isomers were also determined. Cold brew coffee chemistry was compared to tha...
Sample of beer to be measured. Must be fully degassed if it has any carbonation (pour through a coffee filter, or shake and ventilate to decarbonate). Sodium Hydroxide, NaOH. Available in liquid or powder form. Be sure to note its molarity (M), units of mol/L. For more info on mol...
A particularly important attribute of brewed coffee is the perceived sourness, which is known to be strongly correlated to the total titratable acidity (TA). Most prior work has focused on laboratory-scale roasters with little control over the roast profile, so the relationship between roast ...
