Kit vs. Extract vs. All-Grain III: Battle of the Blondes

After the inconclusive previous rounds of testing for Kit v Extract v All-Grain ( round 1 round 2 ), it was decided to have a third round, for the purpose of answering such crucially important questions as:

1) Can you tell the difference between them?

2) Which tastes nicest?

3) Do old kits taste different to new kits?

4) Do beards really help?

In order to make it completely bullet-proof we went for a beer where off-flavours had nowhere to hide: a light lager-like ale. What could possibly go wrong?
