Brewing Process

Water Quality

The water used to make coffee matters. Filtering your water or checking its pH can reduce how acidic your coffee is.

The Cold Brew Difference

The cold brew process makes coffee taste less acidic, smoother, and richer. This method involves steeping coarse coffee grounds in cold water for a long time. It typically takes 12 to 24 hours. The result is a cold brew coffee that’s 70 percent less acidic than hot-brewed coffee.

Slow Steeping Process

What makes cold brew special is its slow-steeping process. By steeping coffee for a long time, it allows gentle extraction. This pulls out the good stuff softly, keeping the flavors and aromas intact. The outcome is a smoother and richer flavor that’s not bitter.

Reduced Acid Extraction

Cold brew’s key advantage is its low acid levels. The cold water doesn’t pull out as much acid as hot water does. This makes it gentler for people with sensitive stomachs.
