I remember my first office jobs, years ago now, when a lunchtime beer was commonplace. You can imagine the post-lunch slump. If you wanted to avoid that, you had to forego grown-up flavours and switch to overly sweet soft drinks, or stick to water. Small beer gives more choice to drinkers who want to enjoy themselves and keep a clear head at the same time.
The light lager (2.1% ABV) is crisp and refreshing with a snappy and slightly floral hop finish - just what you'd look for in a classic pilsner.
The dark lager (1% ABV) is crisp again and light on the palate, with a roasted, dark fruit character and a hint of smoky malt to it.
The only clue to the reduced ABV in these beers is a slightly lighter feel on the palate, but unlike with traditional low-alcohol lagers you don't get that feeling of being short-changed.
This is because Felix and James brew to strength. The more common process is to brew a full-strength beer as normal and then strip out the alcohol afterwards. Unfortunately this also takes a lot of the flavour away with it.
