In Indonesia, the high ambient temperature and humidity create a significant demand for vessels that can maintain liquid temperatures. The shift from traditional plastic to a double walled cup has become evident in major cities like Jakarta and Surabaya, where consumers seek a balance between aesthetic elegance and thermal efficiency.
The local hospitality sector is experiencing a surge in "Instagrammable" cafe culture. This has driven the demand for insulated coffee glasses that showcase the layered colors of specialty lattes while preventing condensation from forming on the outer surface, which is a common pain point in the humid Indonesian climate.
Economically, the growth of the middle class in Southeast Asia has transitioned the market from mass-produced low-cost glass to specialized borosilicate products. There is now a clear preference for durable, lightweight, and chemically stable glassware that can withstand the rapid temperature changes typical of iced coffee trends in the region.
