Selfsame decaf coffee provides an appealing solution for those suffering from heartburn, acid reflux or sensitive stomachs who enjoy coffee but experience symptoms such as heartburn and acid reflux. By eliminating caffeine’s natural stimulant effect on stimulating central nervous system cells that in turn produce more acid levels, decaf reduces these issues with its same process that also lessens its astringency levels – providing all of the natural flavors while eliminating those acidic compounds which could exacerbate stomach conditions such as acid reflux or indigestion.

Location, elevation at harvest and roasting technique all affect the acid content of your beverage. Beans grown at higher altitudes tend to have lower acidity than those from lower elevation areas; dry processing or longer dark roasts may also help lower astringency levels.

Milk or cream can help neutralize acidity in brew, but for some this doesn’t provide long-term relief. There are other strategies available to you for decreasing acidity such as brewing at lower temperatures for longer, using coarser grounds, and including eggshells in your recipe.

On the pH scale, coffee typically registers around 4.7, significantly more acidic than lemon juice or cola. This may explain its astringency; perhaps its astringency stimulates sympathetic brain activity by encouraging HCL production and acid release.
