A bottle capper is a device used to seal beer bottles after the beer has finished fermenting. It works by crimping a metal cap onto the top of the bottle, creating an airtight seal that keeps the beer fresh and carbonated. The bottle capper is an essential tool for homebrewers who want to share their beer with others or store it for later consumption.

There are two main types of bottle cappers: handheld and benchtop. Handheld cappers are small and portable, making them a popular choice for homebrewers who brew in small batches. They are designed to be used with crown caps, which are the most common type of bottle cap used in homebrewing. To use a handheld capper, you simply place the cap onto the bottle, position the capper over the cap, and squeeze the handles together to crimp the cap onto the bottle.

Benchtop cappers, on the other hand, are larger and more powerful than handheld cappers. They are designed to be mounted to a table or benchtop and are used with a lever or foot pedal to apply pressure to the cap. Benchtop cappers can be used with a variety of cap sizes, making them a versatile option for homebrewers who brew in larger batches or who want to experiment with different types of caps.

When choosing a bottle capper, there are a few things to consider. First, consider the type of cap you will be using. Most homebrewers use crown caps, but some may choose to use swing-top caps or cork and cage caps. Make sure the capper you choose is compatible with the type of cap you plan to use.

Second, consider the size of your batches. Handheld cappers are great for small batches, but if you plan to brew larger batches, you may want to invest in a benchtop capper. Benchtop cappers are more powerful and can apply more pressure to the cap, ensuring a tight seal.

Finally, consider the quality of the capper. A good bottle capper should be durable and well-made, with a sturdy base and a comfortable grip. Look for cappers made from high-quality materials that will last for years.

Using a bottle capper is easy, but there are a few tips to keep in mind to ensure a tight seal. First, make sure the cap is centred on the bottle before crimping. If the cap is off-centre, it may not seal properly. Second, make sure the capper is applying enough pressure to the cap. If the cap is not crimped tightly enough, the beer may lose its carbonation or become contaminated.
