White Claw Surge contains an ABV of 6.5%, up from 4.5% on the original. Higher than most hard seltzers, but less than an average glass of wine. So you can enjoy one or two without worrying about waking up two days later in another state, with a lampshade on your head. 

But there is a caveat: more alcohol equals more calories – Surge contains 220 calories per 330ml can, compared to 95 for the standard White Claw seltzers. However, the carb-phobic among you can take heart – Surge is still low carb, containing only 2g carbs per can, so you can indulge with relative impunity.
