Batch Plants and Beer: Why Breweries Break Manufacturing Rules

Episode 4 of our brewery automation series digs into ISA-88, the industrial standard that uses breweries as its textbook example. We explore why a brewery classifies as a 'batch plant' rather than discrete or continuous manufacturing—and why this classification is the biggest open question in our control logic design.
