“…As others have shown, optimal firm size increased during the late 19th because larger batch sizes enabled more efficient use of existing plant and equipment, while new technologies such as bottling plants only became feasible at larger scales of production (Deutsher, 2012, p. 83; Hawkins & Pass, 1979, Chapter 2; Merrett, 1998, p. 206; Muris et al, 1992; Stubbs, 1999, p. 87).

This made it easier for large, metropolitan breweries to export beyond saturated local markets and increase the returns to scale on plant and equipment.…”
