From ancient brewing traditions to today’s thriving craft beer culture, the journey of beer is deeply tied to the evolution of its packaging. While brewing techniques have advanced over the centuries, one constant remains: glass is still the most trusted material for bottling beer. And today, companies like GlassRock are helping reshape the future of beer packaging with smarter, stronger, and more sustainable glass solutions.
Though beer predates many modern civilizations, it wasn’t until centuries later that it was stored in bottles. Early brewers relied on barrels and stoneware, but by the late 1600s, glass began to emerge as a vessel of choice. The shift didn’t come without challenges, early glass bottles struggled to withstand the pressure from fermentation gases, often shattering under the strain.
Eventually, the now-iconic longneck bottle was introduced, a shape that helped distribute internal pressure more evenly and prevent breakage. This simple design innovation remains a staple in the beer industry. Today, GlassRock continues this legacy by engineering beer bottles that combine durability with design flexibility, offering custom shapes and finishes without compromising on performance.
Glass became popular for one key reason: it keeps beer fresher, longer. But early use of clear glass led to an unexpected problem , beer stored in sunlight would take on a foul, skunky aroma. We now know this was caused by UV rays altering the compounds in hops.
The solution? Amber (brown) glass, which filters out most harmful UV light and preserves the flavor. Green bottles later gained popularity as a stylish alternative, especially in Europe, while today’s brewers can also use blue glass to make the bottle more outstanding.
GlassRock produces all three variations , amber, green, and blue, helping brewers match their brand identity while ensuring product quality.
