So we've enjoyed all of the pressure barrel of Coopers Mexican Cerveza as we've got as much out of it as we can, even with tilting the thing so it'll be on to the 500ml bottles that have been sat in the dark, cool garage for the last few weeks.
I'll post how they are when we pop the first ones open but the Cerveza from the pressure barrel has been very enjoyable. It improved with a slice of lime and also for being served in a chilled glass. The head retention was superb although only when drunk relatively cool as chilling a glass in the fridge for a while only allowed the beer to go flatter.
Too early to decide whether I'd brew this kit again - depends on the bottles.
