What's the difference between cold brew and regular coffee?

Hey Priyanka, Cold brew is never heated during the brewing process- the ground coffee is brewed in room temperature or cold water, and then refrigerated. However, your usual coffee will be either brewed and served hot like a latte or cappuccino (or just plain black coffee) or it is brewed hot and then cooled down and served cold like an iced Americano. Temperature plays a huge role in extraction so the temperature while brewing affects the strength, rate of extraction, and flavor. Since cold brew needs cold water, there’s no heat to act as a catalyst to extract compounds from the beans. For this reason, cold brew takes 16-24 hours to brew! The prolonged extraction period also makes cold brew more caffeinated and less acidic. Cold brew has a smooth taste which has made it very popular in recent years. Which is better? I really couldn’t choose. Both cold brew and hot coffee have their own edge. Some days you want to chill with cold brew, and some days you need the warmth of a hot cup to brighten the day. Whichever you prefer, always go for specialty coffee and the fresher the better!
