Tylers Coffee offers acid free coffee through its proprietary Z-Roasting process, eliminating all harmful Tannic and Lipid acids produced during regular roasting that cause bitter bite, upset stomach and tooth enamel damage compared to regular coffee. Our low acid coffee has a pH between 4.5-5.2 for maximum enjoyment – enough for coffee lovers everywhere! Additionally, unlike its competitors we never refer to our product as stomach-friendly or compatible espresso since this labeling would violate Germany law as they don’t qualify as acid free beverages! Tylers remains the only true acid free coffee available anywhere worldwide!
