I LOVE Alice Red as it gets round the age-old problem of being tired but not being able to stomach the taste of Red Bull. This vodka comes with guarana, creatine, d-ribose, and natural caffeine and delivers 41.25% ABV. This vodka tastes great--and it's made in the UK!
Alice Red contains 160mg Caffeine per 100ml, so a double shot has basically the same levels of caffeine as found in a can of energy drink. That is what I call a result!
Alice is hard to source, but do yourself a favor and make the effort to buy it online. You wont regret it!
