Beer is good. Wasted beer is bad. The Primanti Bros. chain in early 2023 tested a new technology, called BeerBoard, that tracks the number of beers poured versus the number of beers sold. The idea is to ensure that bartenders are pouring the correct number of beers. The company liked it so much that the technology was expanded to all 42 restaurants. The result: A 300-basis-point reduction in the cost of draft beer sold.
