This article contains a typographical error in the Methods section under subheading ‘Coffee’ where,


"Brewing water was prepared by dissolving 1.16 g CaSO4·2H2O, 4.97 g MgSO4, 3.26 g NaHCO3, and 2.57 g KHCO3 per litre of deionized water and leaving the solution to equilibrate with ambient CO2 until a stable pH near 7 was reached, as specified by industry standards53.”


should read:


“Brewing water was prepared by dissolving 1.16 g CaSO4·2H2O, 4.97 g MgSO4, 3.26 g NaHCO3, and 2.57 g KHCO3 per 100 litres of deionized water and leaving the solution to equilibrate with ambient CO2 until a stable pH near 7 was reached, as specified by industry standards53.”
