It’s prepared the same way you would make a cup of hot coffee. You can use a drip machine, pour-over, percolator, french press, or any other method. Once it’s brewed, the hot coffee is chilled in a refrigerator and then served!
Cold brew is a method of making coffee without heating the grounds. Instead, coarse grinds are steeped in room temperature water for several hours. The result is less bitter and acidic than hot brewed coffee.
SIMILARITIES
The only similarity the two drinks have in common is their presentation...and additional mix-ins! Coffee lovers adding different types of milks and syrups to spice up these two drinks.
DIFFERENCES
The main difference between the two is, iced coffee is brewed with hot water while cold brew is brewed with cold water. Iced coffee is much less concentrated than cold brew.
CAFFEINE
More caffeine is extracted from hot brewing compared with the cold brew process. At the same time, ice melt makes an iced coffee less concentrated. A cup of hot coffee will have more caffeine than an equal-sized cold brew coffee. But a cold brew coffee will have more caffeine than an iced coffee!
