I must admit, I took the can out of the box, saw the orange colour, and instantly thought "Oh shit, I've had this before and hated it."
Thankfully, Brewdog have either since changed the recipe, or I was having a bad day.
Clockwork is a Tangerine Session IPA, and it certainly smells citrusy. As with most BrewDog beers so far, the taste doesen't quite live up to the smell, but it's a surprisingly tasty beer with a decent flavour that leaves no bitter aftertaste.
I feel like I'm starting to repeat myself a little, but I can imagine this is a good beer to drink a lot of when in the pub, if a pub were to offer this on tap (very unlikely).
