A hammer capper is a simple, cost-effective tool for homebrewers to securely seal beer bottles, and reviews praise its ease of use, affordability, and compact design. It's made of a durable combination of metal and plastic with a non-slip handle and requires a quick strike from a mallet or hammer to crimp a crown cap onto the bottle's neck. Users recommend using a folded cloth to absorb impact and suggest practicing with a rubber mallet to ensure even pressure and a tight seal without breaking bottles.


Pros of Hammer Cappers

• Simplicity & Cost-Effectiveness: The tool has no moving parts and is significantly cheaper than mechanical cappers, making it an excellent choice for beginners and those on a budget



• Portability: Its small, compact design makes it easy to use for anyone with limited space or who brews in different locations



• Professional Look: When used correctly, it creates a professional, high-quality bottle finish



• Good for Homebrewers: It's an essential tool for homebrewers to secure their bottled beer

How to Use a Hammer Capper

• Prepare: Place the bottle on a few folded cloths to absorb the impact and prevent breakage



• Position: Place a crown cap onto the neck of the bottle.



• Capper Placement: Position the capper squarely on top of the crown cap, ensuring it's level



• Strike: Firmly hit the top of the capper with a rubber mallet or hammer until the crown cap is fully crimped around the bottle's neck



• Check: Remove the capper and check that the cap is tightly secured

Tips for Best Results

• Use a Rubber Mallet: A rubber mallet provides more even pressure and is less likely to damage the bottle than a metal hammer



• Practice: It may take some practice to get the right technique, but with practice, you can achieve effective capping



• Use on a Cloth: The folded cloth is crucial for absorbing the shock of the hammer strike, protecting the glass
