As acidity is an unavoidable element of coffee, it may cause discomfort for those with sensitive stomachs and even lead to heartburn and acid reflux in extreme cases. Many choose low acid coffee – made with reduced acidity that’s gentler on the stomach – instead; but many coffee enthusiasts are unfamiliar with what makes up low acid coffee or how best to brew it.

There are various strategies to lower the acidity of coffee. Some brands provide coffee grown from regions naturally lower in acidity while others utilize special processing techniques – water processing, longer roasting times or the addition of eggshells can all reduce acidity levels in beans.

Acidity levels vary based on the brewing method used. Cold brewed coffee tends to have less acidity due to prolonged contact between water and beans resulting in less release of acidity from them.

Roasting also affects acidity levels; darker roasts tend to have lower acidities than lighter ones; however, darker roasts may sometimes obscure other flavors from its origin such as sweetness, fruitiness and floral notes – so when searching for coffees with low acidities it’s essential that you experiment with various roasts and brewing methods until you find something suitable to your palate and that won’t put undue strain on your stomach.
