With the weather getting warmer, many people are turning to cold-brew coffee. But is there actually a difference in caffeine levels between regular coffee and cold brew? According to Huffington Post, there is. The amount of caffeine is upped the hotter the coffee is. One example: a tall brew at Starbucks has 200mg of caffeine whereas a hot coffee can have between 260mg and 360mg. So when you're itching for your caffeine fix in the summer, you might want to grab a hot coffee and bring it inside.
