I’m not a big Dr. Pepper fan because of the high sugar content, but they have a new flavor so here we are. Dr. Pepper Blackberry is berry flavored all right. I wouldn’t say it’s an improvement but then Dr. Pepper is a classic. Maybe it’s the good parts of my childhood that I’m tasting.
Anyway, Dr. Pepper Blackberry has a robust flavor that will lend itself well to most alcohols but I don’t think it will work with tequila. I mean, try it if you like but I think the flavors will clash. It’s a fine change of pace to a classic if the classic is your go to.
