As the peak of the Indian summer approaches, a period that traditionally accounts for nearly 40% of annual beer sales, the Indian brewing industry is sounding a frantic alarm. The escalating conflict between the U.S.-Israel coalition and Iran has moved beyond the realm of geopolitics and energy prices, hitting a critical, often-overlooked component of the beverage industry: the glass bottle.
Major industry bodies and top executives from India’s leading alcobev companies warned on Monday that a “severe shortage” of glass containers and aluminum cans is imminent. The disruption stems from a dual blow to the manufacturing process: a spike in natural gas prices and a literal “shattering” of the logistics network in the Persian Gulf.
To understand why a war in the Middle East stops a bottling plant in Gujarat, one must look at the process of glassmaking. Glass production is an incredibly energy-intensive process. Raw materials like silica sand, soda ash, and limestone must be heated to temperatures exceeding 1500°C to achieve a molten state. Natural gas is the preferred fuel for these furnaces because, it provides a steady, high-intensity flame required for uniform melting, burns cleanly, ensuring that impurities do not discolor the glass or compromise its structural integrity and is extremely economical.
However, with Iran targeting LNG infrastructure (such as the recent disruption of 17% of Qatar’s export capacity), the spot prices for gas in Asia have surged. For Indian glassmakers, who operate on thin margins, this energy spike makes production at current price points nearly “unviable.”
The disruption to the glass supply chain is unfolding in three distinct waves. Currently, domestic glass manufacturers like Hindusthan National Glass (HNG) and AGI Greenpac are facing a 25–35% increase in production costs due to fuel surcharges. Next, Soda ash, a key ingredient in glass, is often imported via the Middle East. With drone activity disrupting shipping lanes in the Gulf, the lead time for these chemicals has doubled. And lastly, although glass is 100% recyclable, and manufacturers rely on “cullet” (recycled glass) to lower melting temperatures and save energy. However, the logistics of moving recycled glass across states are becoming prohibitively expensive due to rising diesel and shipping insurance costs.
The Dry Summer will not affect every player equally. The impact is likely to be felt most acutely by companies with high glass-to-liquid ratios and those targeting the mass market. United Breweries (UBL), the maker of Kingfisher is particularly vulnerable. As the market leader with a massive footprint in the strong beer segment (usually sold in 650ml glass bottles), any shortage in glass supply directly translates to lost volume during their most profitable quarter. Budweiser/AB InBev India have a higher mix of premium cans, however, their reliance on specialized amber glass for premium branding makes them sensitive to specialty glass shortages. Radico Khaitan & Tilaknagar Industries form a part of IMFL (Indian Made Foreign Liquor), which rely heavily on glass for their prestige brands; but unlike beer, which can pivot to cans (though aluminum is also seeing supply shocks), high-end spirits are culturally and functionally tied to glass bottles. Lastly, the MSMEs, small, local craft breweries and regional soda makers will likely be the first to lose their “slots” at glass manufacturing plants, as suppliers prioritize high-volume contracts with multinational giants.
The shortage is more than just a party pooper. The alcobev sector is one of the largest contributors to state exchequers in India. A 10-15% dip in production due to packaging shortages could lead to a significant revenue shortfall for state governments currently balancing their post-election budgets.
Furthermore, this crisis highlights the fragility of India’s Just-in-Time supply chains. If the conflict in the Middle East persists, we may see a forced “packaging evolution,” with companies accelerating the shift toward PET (where permitted) or investing heavily in dedicated “bottle return” circular economies to bypass the need for virgin glass production.
As temperatures soar across the subcontinent, the sight of empty shelves in liquor vends may become common. The “Glass Crisis of 2026” serves as a stark reminder that in a globalized economy, a drone strike in the Gulf can effectively “cork” a bottle thousands of miles away in a Mumbai suburb. For India’s brewers, the coming months will be a test of resilience and a race to find alternatives before the market runs dry.
