When it comes to growlers, there are indeed standard sizes that are commonly used in the industry. The two most common sizes are 32 ounces and 64 ounces. These sizes have become the standard for a few reasons.
Firstly, the 32-ounce size, also known as a “howler,” is a convenient option for those who want to enjoy a smaller quantity of beer. It's perfect for individuals who may not want to commit to a full 64-ounce growler or for those who want to sample a variety of different beers without consuming too much in one sitting.
On the other hand, the 64-ounce growler, often referred to as a “growlette” or “growler,” is the more popular size and is commonly seen at breweries and beer shops. This size allows for a larger quantity of beer, making it ideal for sharing with friends or enjoying over a longer period of time.
One of the advantages of growlers is their refillable nature. You can bring your empty growler to a brewery or beer shop and have it refilled with your favorite beer on tap. This not only reduces waste but also allows you to try a wide variety of beers without needing to purchase individual bottles or cans.
In my personal experience as a sommelier and brewer, I have found that the 64-ounce growler is the most versatile and practical size. It provides enough beer to share with friends or enjoy over a few days, while still maintaining the freshness and carbonation of the beverage. Additionally, many breweries offer special deals or discounts on refills when using a 64-ounce growler, making it a more cost-effective option in the long run.
That being said, the 32-ounce growler does have its benefits, especially for those who prefer smaller portions or want to sample a variety of beers. It can be a great option for individuals who are new to craft beer or who want to try different styles without committing to a larger quantity.
While there isn't necessarily a “standard” growler size, the 32-ounce and 64-ounce sizes have become the most commonly used and recognized options in the industry. The choice between the two ultimately comes down to personal preference and intended use.
