Slightly different to the taste I was expecting - the usual energy shot flavour is one that's very bitter with quite a nasty aftertaste, but this one was instead very sharp with a sweet aftertaste. It still made me draw back my lips from my teeth and make a hissing sound, but it was nowhere near bad enough to make me question my motives in trying the shot this time. It's pretty high in caffeine even for a shot and gave me a boost in pretty much record time... not a drink to be taken lightly!
