Apologies for the belated posting on Thursday's monumental Arthur's Day. But, good things come to those who wait.
To get the "perfect" pint of Guinness the time between the first and second pour must be precisely 119.53 pub seconds. This is to allow the organisms in the nitrogen to grow the perilous N2 compounds which, in turn, create enough energy to burn or decay back into nitrogen gas and flow into your pint.
If you were to start the second pour after 119.52 seconds or wait until 119.54 seconds, this would render the porter entirely unpotable.
Happy Birthday Sir Arthur!
