Since the founding of GEMOSS in 1993, our main home has been the cash & carry at Mūkusalas street 73, but today we have 5 more stores to call home: a historic port warehouse in Liepāja, a former grain storage in Valmiera, two stores and a large production facility in Riga, and a store in Tallinn, Estonia. .
