By the early 1890s, the firm had more than 50 workers and produced up to 300,000 buckets of beer — a common unit of measurement in brewing and vodka-making industry in 19th century Russia and corresponding to roughly 12.3 litres.

Epstein significantly modernized the brewery and by 1909, it had four electrical motors and a diesel engine running the brewing process — a novelty in early-20th-century Europe.

Such investments allowed for the brewery to almost monopolize the local market: the yearly production prior to World War I reached 800 thousand buckets, that is almost 10,000 hectolitres.

Although the Great Depression of late 1920s stroke the business, the yearly production rate continued to increase and reached 30,000 hectolitres in the early 1930s.

Merged with several smaller producers of beer and soft drinks, the company was renamed to its current name, Tauras Brewery, shortly after the end of World War II, in 1945.
