Why are they called demijohn?

Answered by Michael Weatherspoon

As an expert sommelier and brewer, I can shed some light on the origins of the term “demijohn.” The word itself is believed to have originated from the French term “dame-jeanne,” which translates to “Lady Jane.” This name was commonly used to refer to any glass vessel with a large body and small neck, typically enclosed in wickerwork.

The exact reason behind the choice of this name is not entirely clear, but it is likely that the term “Lady Jane” was a popular appellation given to such vessels in France during the 17th century. It's fascinating to think about how certain names and terms have evolved over time and become commonly used in specific contexts.

In my personal experience, I have come across demijohns in various wineries and breweries. These vessels are often used for fermenting and storing liquids such as , , or even . Their large body allows for a larger volume of liquid to be contained, while the small neck helps to create a seal and prevent excessive exposure to air.

The use of wickerwork as an enclosure for demijohns also adds an interesting touch. The wicker provides some insulation and protection, making it easier to handle and transport these glass vessels. I remember observing the careful craftsmanship that went into creating the wickerwork around a demijohn during a visit to a traditional winery in France. It was truly a sight to behold and a testament to the artistry involved in winemaking.

While the term “demijohn” may not be as commonly used today, especially in winemaking and practices, it still holds historical significance and reminds us of the traditional methods and vessels that were once widely employed. It's always intriguing to explore the etymology of words and uncover the stories behind them.

To summarize, demijohns are called so because of their association with the French term “dame-jeanne” or “Lady Jane.” This name was likely given to these glass vessels due to their large body and small neck, which resembled the shape of a traditional woman's figure, hence the feminine appellation. The wickerwork enclosures further added to their unique charm and practicality.
