What is a Growler? A Complete Guide
A growler is a reusable container, typically glass or stainless steel, used to transport beer from a brewery or pub. It allows you to enjoy fresh, draft beer at home without committing to a full keg. But growlers are more than just convenient containers; they represent a connection to local breweries and a commitment to enjoying quality beer.
History of the Growler
The term "growler" has a colourful history, with a few different origin stories floating around. One popular theory dates back to the late 19th century when beer was often carried home from local pubs by children in galvanised pails. As the beer sloshed around, the carbon dioxide escaping from the beer created a rumbling sound – hence the name "growler".
Another theory suggests the name comes from the saloon patrons themselves. It's said that they would complain or "growl" if their beer wasn't filled to the brim. Regardless of the exact origin, the growler became a common way to transport beer before the widespread availability of bottled and canned beer.
While the original growlers were often open pails or pitchers, the modern growler is a sealed container designed to preserve the beer's carbonation and freshness. This evolution has made growlers a popular choice for beer enthusiasts who want to enjoy draft beer at home.
Types of Growlers
Growlers come in a variety of materials and designs, each with its own advantages and disadvantages. Here's a look at some of the most common types:
Glass Growlers: These are the most traditional type of growler. They are relatively inexpensive and easy to clean. However, glass growlers are susceptible to breaking and don't insulate the beer, meaning it will warm up faster. They also allow light to penetrate, which can skunk the beer over time. Clear glass offers no protection, while amber or brown glass provides some UV protection.
Stainless Steel Growlers: Stainless steel growlers are more durable than glass and offer better insulation, keeping your beer colder for longer. They are also opaque, preventing light from affecting the beer. Stainless steel growlers can be more expensive than glass, but their durability and performance make them a worthwhile investment. Some stainless steel growlers are vacuum-insulated for even better temperature control.
Ceramic Growlers: Ceramic growlers offer a unique aesthetic and can provide good insulation. They are often more decorative than other types of growlers, making them a popular choice for gifting. However, they can be more fragile than stainless steel and may be more difficult to clean thoroughly.
Plastic Growlers: While less common, plastic growlers are lightweight and durable. However, they are generally not recommended for long-term storage as they can allow oxygen to permeate and affect the beer's flavour. They are also less environmentally friendly than reusable glass or stainless steel options.
Pressurised Growlers: These growlers use a CO2 cartridge to maintain pressure inside the container, keeping the beer carbonated for longer. They are a more expensive option but are ideal for those who want to enjoy beer over several days without losing carbonation. These are great for preserving the beer's original quality.
When choosing a growler, consider your needs and priorities. If you're looking for an affordable and easy-to-clean option, a glass growler may be sufficient. If you prioritise durability and insulation, a stainless steel growler is a better choice. For ultimate freshness, consider a pressurised growler.
Benefits of Using Growlers
Using growlers offers several benefits for both the consumer and the brewery:
Fresh Beer at Home: Growlers allow you to enjoy fresh, draft beer from your favourite brewery in the comfort of your own home. This is especially appealing for beers that are not available in bottles or cans.
Support Local Breweries: By purchasing growlers from local breweries, you are directly supporting their business and helping them thrive. This fosters a strong connection between the brewery and its community. You can learn more about Growlers and our commitment to supporting local businesses.
Reduced Waste: Growlers are reusable, which helps reduce waste compared to single-use bottles and cans. This makes them a more environmentally friendly option for enjoying beer. By choosing growlers, you're contributing to a more sustainable drinking culture.
Cost Savings: While the initial investment in a growler may be higher than buying a six-pack, filling a growler is often more cost-effective in the long run. Breweries typically offer discounted prices for growler fills, making it a budget-friendly way to enjoy draft beer.
Variety and Selection: Growlers give you access to a wider variety of beers than you might find in bottles or cans. Many breweries offer a rotating selection of seasonal and limited-release beers on tap, which you can take home in a growler. This allows you to explore different styles and flavours.
How to Clean and Maintain Your Growler
Proper cleaning and maintenance are essential for keeping your growler in good condition and ensuring that your beer tastes its best. Here are some tips:
Rinse Immediately After Use: The most important step is to rinse your growler with hot water immediately after emptying it. This will prevent beer residue from drying and becoming difficult to remove. Don't let the beer sit overnight!
Use a Mild Detergent: For a more thorough cleaning, use a mild, unscented detergent. Avoid using harsh chemicals or abrasive cleaners, as these can damage the growler and affect the taste of your beer. Baby bottle soap is a good option.
Use a Growler Cleaning Brush: A long-handled brush specifically designed for cleaning growlers can help you reach all the nooks and crannies. This is especially important for glass growlers, which can be difficult to clean thoroughly.
Sanitise Regularly: To prevent the growth of bacteria and mould, sanitise your growler regularly. You can use a food-grade sanitiser or a solution of diluted bleach (1 tablespoon of bleach per gallon of water). Be sure to rinse thoroughly after sanitising.
Air Dry Upside Down: After cleaning and sanitising, allow your growler to air dry completely upside down. This will prevent moisture from accumulating inside, which can lead to mould growth. Ensure the growler is completely dry before storing it.
Store with the Lid Off: When storing your growler, leave the lid off to allow air to circulate. This will help prevent the development of musty odours. You can also store a crumpled piece of paper towel inside to absorb any remaining moisture.
Avoid Dishwashers: While some growlers may be dishwasher-safe, it's generally best to hand wash them to avoid damage. The high heat of the dishwasher can also affect the beer's flavour.
By following these cleaning and maintenance tips, you can keep your growler in top condition and enjoy fresh, delicious beer for years to come. If you have any questions, check out frequently asked questions about growler care.
Growler Filling Best Practices
To ensure that your growler is filled properly and that your beer stays fresh, follow these best practices:
Ensure the Growler is Clean: Before taking your growler to be filled, make sure it is clean and sanitised. This will prevent any contaminants from affecting the beer's flavour.
Purge with CO2: Ask the brewery to purge the growler with CO2 before filling it. This will remove any oxygen from the growler, which can cause the beer to go stale more quickly. This is a crucial step for preserving freshness.
Fill from the Bottom Up: The brewery should fill the growler from the bottom up to minimise foaming and oxygen exposure. This technique helps to preserve the beer's carbonation and flavour.
Leave Minimal Headspace: The brewery should leave minimal headspace in the growler to reduce the amount of oxygen in contact with the beer. This will help to keep the beer fresh for longer.
Seal Tightly: Ensure that the growler is sealed tightly after filling. A loose seal can allow oxygen to enter and cause the beer to go flat. Check the seal before leaving the brewery.
Keep Cold: Store your filled growler in the refrigerator as soon as possible. This will help to slow down the rate of carbonation loss and keep the beer fresh. Temperature control is key.
Consume Promptly: For the best flavour, consume the beer in your growler within 24-48 hours of filling. While some pressurised growlers can keep beer fresh for longer, it's generally best to drink it as soon as possible.
By following these filling best practices, you can ensure that your growler is filled properly and that your beer stays fresh and delicious. Consider what Growlers offers in terms of growler filling and maintenance to ensure you are getting the best possible service. Enjoy your fresh, local beer!
