Many people struggle to enjoy coffee without heartburn and stomach upset, and more and more people are turning to low acid coffee as an alternative. Instead of cutting back on acidity in their regular beverage, many opt for making their own low acid coffee at home using cold brew technology, providing for a full-bodied flavor experience while eliminating acidity that causes heartburn or upset stomach.

Acid content of coffee depends on multiple factors, including bean type and roasting method; darker roasts typically possess lower acid levels than lighter varieties. Furthermore, grind size can impact how much acid is extracted during brewing – for instance coarser grinds allow longer steep times and better flavor encapsulation while simultaneously decreasing acid release.

Other factors that can alter the acid content of a cup of coffee include water temperature, filter status and how the brewed coffee is prepared. Hotter water extracts more acid from coffee beans while over-extracting bitter acids could result in overextraction of bitter compounds.

Cold brewing coffee beans is a proven method to quickly reduce acidity. This is an easy process that you can do at home with some basic tools; for example, Toddy Cold Brew System takes out much of the guesswork by automatically measuring out what quantity of ground beans and cold water will be necessary to create a pitcher of low acid coffee concentrate.
