Ginger beer is often a topic of confusion when it comes to its alcohol content. As a sommelier and brewer, I can provide some insight into this matter. Ginger ale is typically completely alcohol-free, making it a suitable choice for those who prefer non-alcoholic beverages. On the other hand, ginger beer does contain a small amount of alcohol, usually around 0.5 percent by volume. While this may seem like a negligible amount, it is important to note that it is still considered non-alcoholic due to its low alcohol content.
The alcohol content in ginger beer is a result of the fermentation process. During the brewing of ginger beer, yeast is added to a mixture of ginger, sugar, and water. The yeast consumes the sugar and produces alcohol as a byproduct. This is similar to the fermentation process used in brewing beer, where yeast converts sugars into alcohol and carbon dioxide.
I have personally brewed ginger beer several times, and it is indeed fascinating to witness the fermentation process. The yeast consumes the sugars in the ginger beer base and transforms them into alcohol, resulting in a slightly effervescent beverage with a hint of alcohol. However, it is important to note that the alcohol content in ginger beer is relatively low, so it would take a significant quantity to have any noticeable effects.
It's worth mentioning that the alcohol content in ginger beer can vary slightly depending on the brewing method and recipe used. Some commercial ginger beers may have a higher alcohol content than others. However, these variations are usually minimal and still fall within the non-alcoholic category.
When it comes to storage, ginger ale can be easily stored in glass bottles during the brewing process. However, commercial ginger beers are typically carbonated and have a higher pressure buildup, which makes glass bottles unsuitable for storage. Instead, commercial ginger beers are often stored in cans or plastic bottles that can withstand the pressure. This is something to consider if you decide to brew your own ginger beer and want to store it in glass bottles.
To summarize, ginger beer does contain a small amount of alcohol, usually around 0.5 percent by volume. However, this is still considered non-alcoholic due to its low alcohol content. The alcohol in ginger beer is a result of the fermentation process, where yeast converts sugars into alcohol. Commercial ginger beers cannot be stored in glass bottles due to the pressure buildup, while ginger ale can be stored in glass bottles during the brewing process.
