Coffee and Acids: A Quick Overview

Many coffee lovers enjoy their daily brew for its potential health benefits, such as aiding in weight loss and lowering the risk of certain illnesses. However, coffee contains various acids that give it its distinct flavor profile—some of which can be harsh on the stomach.

Did you know that coffee contains nine significant acids? Here’s a quick overview:

  • Chlorogenic: Contributes to weight loss but also makes coffee bitter
  • Quinic: Found in dark and old roasted coffee, can be harmful in high concentrations
  • Citric: Produces a sour taste
  • Acetic: Also produces a sour taste
  • Phosphoric: Adds sweetness to coffee
  • Malic: Another acid that adds sweetness
  • Lactic, Linoleic, Palmitic: Other notable acids in coffee

As much as we adore coffee, it’s important to note that its acidity level, which averages around pH 4.85 to 5.13, can contribute to issues like heartburn and acid reflux. So, what can we do to reduce coffee’s acidity and still enjoy its benefits?

The Magic of Milk: Neutralizing Acidity

Enter milk—a beloved addition to coffee that does more than just enhance its flavor. Milk has a slightly alkaline pH level of around 6.3 to 6.6. When added to coffee, it increases the pH level, making the beverage less acidic.

But how does this work? Milk contains calcium and proteins that act as binding mechanisms to lower or balance coffee’s acids. For example, milk proteins can bind with chlorogenic acids, helping prevent an increase in stomach acid.

Keep in mind, though, that this method works best for dark roast coffee, which has lower pH levels. And if you’re sensitive to dairy, fret not! Non-dairy alternatives like almond, soy, or oat milk can be great substitutes. Here’s a comparison table of different milk alternatives and their pH levels:

Milk AlternativepH Level
Cow’s Milk6.3-6.6
Almond Milk6.4-8.4
Soy Milk6.6-7.6
Oat Milk6.5-7.5

  1. Better Taste: Milk enhances coffee’s sweet, chocolaty, and nutty tones while softening its bitterness—perfect for a creamy, delicious cup.

  5. Calcium: Important for strong bones and teeth

  8. Vitamin B12: Vital for red blood cell formation and brain function Milk is a powerhouse of nutrition, making your coffee more nourishing and beneficial for your overall health.
  9. Safer Temperature: A splash of milk cools down hot coffee, reducing the risk of burns and ensuring a safer, more enjoyable drinking experience.
