TL;DR: Beer has been brewed for over 5,000 years, but storing it in glass bottles was not commercially viable until the 17th century, and not affordable for most consumers until iron bottle molds arrived in 1847. In 1934, Harry Ennever of Harrington Park, New Jersey patented a square ornamental bottle design that challenged the long-dominant round form. Original patent art prints of Ennever's design are available framed or unframed.
Beer is older than writing. The earliest known recipe is a Sumerian hymn to Ninkasi, the goddess of brewing, carved on a clay tablet around 1800 BC. But evidence of fermented grain beverages dates to at least 3500 BC in Mesopotamia and possibly earlier in China. For most of that history, beer was stored in clay pots, wooden barrels, and ceramic jugs. Glass bottles, the container that defined beer as a commercial product for the modern era, did not enter the picture until around the 16th century, and they nearly failed before they succeeded.
Beer Before Bottles: Clay, Wood, and Ceramic
The oldest beer storage vessels were made from clay. Mesopotamian and Egyptian brewers stored their fermented grain beverages in amphora-shaped clay containers sealed with stoppers or cloth. These vessels were adequate for short-term storage and local consumption but were heavy, fragile in transport, and unsuitable for export over long distances.
Wood became the dominant large-scale beer storage material in the European brewing tradition. Wooden barrels, shaped by coopers, could be rolled rather than carried, stacked efficiently, and used repeatedly. The barrel trade and the brewing trade grew up together in medieval Europe, with cooper guilds occupying an essential position in the economy of every town with a working brewery. Beer for domestic consumption was typically drawn from the barrel into ceramic jugs, earthenware mugs, or pewter vessels at the point of sale.
The first experiments with storing beer in glass bottles began in the 16th century, driven by curiosity about whether glass could preserve beer quality better than wood or ceramic over time. These early efforts ran immediately into a materials problem that would limit glass bottling for over a century: the hand-blown glass of the period was too fragile to contain the carbon dioxide pressure that builds inside a sealed beer container. Bottles exploded. Stoppers were blown out. The challenge of keeping beer carbonated in a sealed glass vessel without the vessel failing was not solved quickly.
17th-Century Bottling: A Luxury Trade
By the second half of the 17th century, commercial beer bottling had begun despite the continued difficulties with glass strength. The solution was not to eliminate the pressure problem but to manage it: bottles were filled with still or only lightly carbonated beer, stoppered tightly with cork, and sold at prices that reflected the labor involved in filling and corking each vessel by hand.
Bottled beer in the 17th century was exclusively a luxury product. The bottles themselves were expensive objects, hand-blown by skilled craftsmen, and each bottle had to be individually filled, inspected, stoppered, and sealed with wax. The cost of a single bottle of beer was beyond the means of most consumers. The primary market was wealthy households and the export trade, where the premium price of bottled beer could be supported by the convenience and prestige of the format.
The characteristic bottle form of the period was the onion bottle or shaft-and-globe bottle: dark glass, a squat rounded body, a long neck, and a sealed glass string-rim below the mouth that helped hold the cork in place. These early bottles were made in England and spread across European and colonial markets. They are now collectible antiques, and specimens occasionally surface in archaeological excavations of 17th and 18th-century sites.
British brewers, particularly those producing strong ales and early porters, became the leading practitioners of commercial bottling in the 18th century. The development of coal-fired furnaces capable of producing denser, stronger glass improved the reliability of bottles, and the reputation of bottled British ales spread globally through trade routes. But bottling remained a hand operation, limiting output and keeping prices high.
Iron Molds and Mass Production: 1847
The transformation of beer bottling from a luxury trade to a mass-market operation required a manufacturing breakthrough. In 1847, Joseph Magown of the United States invented iron bottle molds: a process for pressing and shaping molten glass into standardized bottle forms rather than blowing each bottle individually by hand.
Magown's mold dramatically cut both the cost and the time required to produce a bottle. Where a skilled glassblower could produce a limited number of hand-blown bottles per day, molded glass production ran at industrial speeds. The price of a glass bottle fell sharply. For the first time, bottled beer became an economically viable product for ordinary consumers rather than a premium reserved for the wealthy.
The mold-formed bottle also introduced standardization. Hand-blown bottles varied significantly in shape, volume, and wall thickness. Molded bottles could be produced to consistent specifications, which simplified the filling process and made it possible to develop machinery for filling, inspecting, and capping bottles at scale. Industrial bottling, the operation that underlies the modern beer industry, began with Magown's 1847 mold technology.
The next critical innovation came in 1879, when Henry Barrett, an English inventor, created the screw-top bottle: a bottle with a threaded neck that accepted a screw-on cap rather than requiring a cork to be forced into the mouth. Barrett's design made resealing a bottle possible, improved the seal's consistency, and reduced the labor of the bottling process. It replaced cork as the dominant closure mechanism for bottled beverages over the following decades, though the crown cap, invented by William Painter in 1892, would ultimately become the standard for commercial beer bottling.
Beer Bottles Through the World Wars
Beer bottle consumption grew steadily through the late 19th and early 20th centuries as industrial brewing operations expanded and distribution improved. The World War I period accelerated the trend toward bottled beer in several countries, as military logistics favored the convenience of the individual bottle over the barrel for supplying large numbers of people in diverse locations.
In the United States, Prohibition (1920-1933) interrupted commercial beer bottling entirely for over a decade. When Prohibition was repealed, the American brewing industry rebuilt rapidly, and the beer bottle became central to the new commercial structure of the industry. Brands competed not only on taste but on the appearance and distinctiveness of their bottles, since the bottle was often the consumer's first contact with the product.
This competitive environment created an opening for design innovation. The standard round bottle was functional but undifferentiated. A bottle with a distinctive form could signal premium positioning, attract attention on a crowded shelf, or become associated with a specific brand's identity. Designers and inventors began experimenting with bottle geometries beyond the round standard.
Harry Ennever and the 1934 Patent
In 1934, one year after Prohibition ended in the United States, Harry Ennever of Harrington Park, New Jersey was granted a patent for an ornamental square bottle design. Ennever's bottle retained a round neck and mouth to accept standard caps, but the body was square in cross-section with defined corners and distinctive wall profiles that made it immediately different from every other beer bottle on the market.
The square bottle was not entirely novel as a concept: spirits bottles and some condiment containers had used square or rectangular forms for years. But applying the square format to beer, a product with strong associations with the traditional round bottle, was a deliberate design statement. Ennever's patent protected the specific ornamental details of his design, the corner profiles, wall geometry, and proportions, rather than the square format itself.
Ennever went on to patent two additional bottle forms during his career, demonstrating a sustained interest in bottle design as an area of invention. His 1934 square bottle was not widely adopted by the mainstream beer industry, which maintained the round bottle as its standard. But it represents the moment when the beer bottle became an explicit subject of design ambition in America, a trend that has continued through the craft brewing era into the present, when distinctive bottle forms are again a primary brand differentiator.
The beer bottle's journey from an explosive hand-blown luxury object in the 16th century to the precisely engineered, standardized, instantly recognizable container of the 21st is a story about manufacturing, chemistry, distribution logistics, and the commercial desire to make an ordinary object stand out. Ennever's 1934 patent is one moment in that story, and the original drawing of it is one of the more distinctive pieces of patent art in the collection.

Frequently Asked Questions
When was the beer bottle invented?
Brewers began experimenting with glass beer bottles in the 16th century, but commercial bottling did not become viable until the second half of the 17th century. Early bottles were hand-blown, expensive, and prone to failure under carbonation pressure. Mass-market beer bottles became possible after Joseph Magown invented iron bottle molds in 1847, which dramatically reduced production costs.
Who invented the screw-top bottle?
Henry Barrett, an English inventor, created the screw-top bottle in 1879, introducing a threaded neck that accepted a reusable screw-on cap rather than requiring a cork. The screw-top improved seal consistency and reduced the labor of the bottling process. William Painter's crown cap, invented in 1892, later became the dominant closure for commercial beer bottles.
Why were early glass beer bottles so expensive?
Early glass beer bottles were expensive for two reasons: the bottles themselves were hand-blown by skilled craftsmen and varied significantly in quality and size, and each bottle had to be individually filled, inspected, and corked by hand. Before Joseph Magown's iron bottle molds in 1847, the labor involved in producing and filling each bottle kept prices beyond the reach of most consumers, limiting bottled beer to wealthy households and the export market.
What did Harry Ennever's 1934 patent protect?
Harry Ennever of Harrington Park, New Jersey patented an ornamental square beer bottle design in 1934, the year after Prohibition ended in the United States. His design retained a standard round neck and mouth to accept commercial caps but featured a square cross-section body with distinctive corner profiles and wall geometry. The patent protected the specific ornamental details of his design rather than the square format generally. Ennever went on to file two additional bottle patents during his career.
What is the history of beer bottle standardization?
Beer bottle sizes and forms were not formally standardized until the 20th century, when large commercial brewers and bottling operations needed consistent specifications for filling machinery and packaging. The 12-ounce bottle became the American standard through the mid-20th century. Earlier, bottle volumes varied by maker and region. Iron molds introduced by Joseph Magown in 1847 were the first step toward standardization, enabling consistent production of bottles to specific forms, but the commercial and regulatory standardization of sizes took decades longer.
