Grolsch knew that to compete with its main competitor Heineken in the international beer market, it needed to globalize. It started by expanding in Europe where it was from originally, and then globally entered markets like the US, Canada, New Zealand, Australia, and India. This globalization proved very successful as over half of Grolsch's total sales eventually came from international markets. However, Grolsch also learned it needed to adapt to local tastes and partner with local brands in different countries to be successful long-term in those markets.
