In the early 1900s, the Czech economy and our breweries enjoyed relative growth and the mood in society seemed to be optimistic. Both breweries took advantage of this. Their production volumes increased, the breweries began to expand, and that brought about the need for equipment upgrades. Development was boosted by two important events that occurred in the last years of the 19th century: the advent of refrigeration and the invention of mass bottling technology.
Staropramen Brewery purchased additional land needed to expand production.In Ostravar, a new industrial rail spur was built, among other things. The breweries enjoyed a successful period.
However, in this same period competition began to intensify among breweries, especially in Prague, where several large breweries were operating, e.g. Měšťanský pivovar in Královské Vinohrady and První měšťanský pivovar, as well as a number of smaller breweries.
As a result of the competitive struggle, Staropramen was first registered as a trademark in 1911 and the Staropramen Brewery also registered sixteen additional trademarks. Among them were names such as Pračep, Starosmíchovský, and Starozdroj. After a few years, though, only one of the trademarks registered at that time was appearing on bottle labels - Staropramen.
