For those unfamiliar, cold-brewing coffee is basically steeping coffee for long periods of time rather than brewing it with heat. Technically, it's not necessarily cold and can be done at room temperature. The resulting coffee contains less of the harsher bitter acids than brewing with heat and typically results in a smoother cup. It's usually found at third-wave, artisan-type coffee shops.
Prices on Starbucks' Cold Brew Coffee ranges from $2.45 for a 12-oz Tall to $3.95 for a 31-oz Trenta.
While Starbucks is the biggest coffee chain, it's a little bit late to the party on this one. Earlier this week, Chick-fil-A started offering cold-brewed iced coffee. Rival coffee chain, Caribou Coffee, is also offering cold-brewed iced coffee this summer.
