New research from the School of Continuous Improvement follows 318 tap lines for fourteen months and finds a local-share licence condition met at every inspection over a period in which local product accounted for a fifth of what was actually poured.
A competing-risks study of 318 tap lines across 26 licensed venues finds a condition satisfied by product that lingers rather than product that moves.
Counting the taps along a bar takes an inspector about a minute. Following what those taps go on to pour took the School of Continuous Improvement fourteen months, and the two exercises describe the same 26 venues rather differently.
The Slow Keg Holds the Line, a research poster released today, follows 318 tap lines from the day a keg is coupled to the day the line is handed to something else. Lines carrying local product end because the keg has emptied in 29 per cent of cases by day 60; lines carrying everything else do so in 87 per cent. The balance is rotated off part-full. Every venue in the study satisfied its half-of-taps local-share condition at every one of the 41 inspections in the window, over a period in which local product accounted for 19 per cent of poured volume.
A condition is a piece of measurement before it is a piece of policy, and it will be satisfied in whichever way turns out to be cheapest. Our interest is in which way that is.

The study pairs a weekly census of every tap board with the venues’ own delivery and return dockets, and treats the two ways a line can end as competing outcomes rather than as one. “It sits comfortably beside what the University has been learning about the difference between a stock and a flow,” said Dr Marek Solheim, Lecturer in the School of Emergent Priorities.
The release extends a steady institutional interest in the settings by which compliance is established, and in the distance between an indicator and the thing it is trusted to stand for.
