I’d say the top reason to DIY your cold brew over buying it is to save money! The average bottle of Chameleon cold brew costs $9.99, which adds up to about $2 per serving. Between my husband and I, we were going through about 2 bottles a week – which adds up quickly! Depending on which beans you buy, you can usually make your cold brew for right around $1 per serving. The other thing I like about making my own is that I can control the caffeine content. As noted above, cold brew has more caffeine than your typical cup of coffee. Since I’m caffeine-sensitive, but love the lower acidity, I use a half-caff coffee to make mine, which means I can drink my cold brew without getting jittery!
