How to Force Carbonate Beer

Carbonation is a key element of beer brewing, and force carbonating your own beverage can transform it from a flat, boring brew into a magical tipple with a pleasant level of carbonation.

There are several methods for achieving this, but here we’ll look at how to force carbonate beer.

What is Force Carbonating Beer?

Force carbonation is the process of adding carbon dioxide directly to your beer before it has been packaged and sealed.

This method usually produces a more consistent level of carbonation than any other process.

The main benefit of using this technique is that you can customize the amount and type of bubbles in your beer to give it the ideal amount of effervescence for your taste.

Understanding the Process

When done correctly, force carbonating your beer will give it an even level of carbonation throughout its body—something that cannot be achieved by natural or bottle conditioning methods.

Achieving this effect isn’t difficult, but you will need to understand the principles and procedures involved in order to do it right.

Preparing the Beer for Force Carbonation

Before you begin force carbonating, make sure your brew is ready by cleaning and sanitizing all your equipment properly:

  • Kettle or fermenter
  • Fittings
  • CO₂ cylinder and regulator

Then transfer the wort from the kettle or fermenter into the keg without aerating it too much. The pressure should be kept low until the beer has fully cooled down – below 12°C.

You can then attach an inline oxygen scavenger directly after transferring your brew for added protection against oxidation.

Finally, use a low-pressure purge method to purify nitrogen or CO₂ gas over your keg up to 1-2 psi (7-14 kPa). This will remove any remaining oxygen from the headspace which may otherwise ruin your final product.

Now you’re ready to begin force carbonating!

Setting Up the Rig

You’ll need two connections – one for gas (carbohydrate) and one for liquid (outlet). Connect them both together with their accompanying fittings then plug in your regulator so you can start adjusting pressure levels.

Next up attach a CO₂ cylinder to your regulator by firmly pressing down, making sure both components are securely connected.

Then set up a tube going from the gas line connection towards the cylinder ensuring no kinks as bends in tubing occur – this helps maintain an even flow of gas when pressure regulating later on.

Lastly, turn the valve knob beside the regulator clockwise so the hose connection between the cylinder and regulator is closed off preventing any backflushing within the system when not in use. Now you’re ready to add CO₂ directly into the keg!

Adding Carbon Dioxide and Controlling Pressure

Start adding CO₂ gradually until desired psi (7-14 kPa) level has been reached; make sure not to overfill with too much pressurization as this causes the foam to overflow out of the keg when tapped later on!

To adjust levels simply manipulate the valve knob either left or right until the desired amount is reached – the left depletes pressure whilst the right increases volume within the system giving more control over individual psi values!

Maintaining and Adjusting Pressure

Once desired pressure has been achieved ensure maintenance procedures are followed regularly ensuring no inconsistencies happen when pouring drinks later on!

Keep track daily of how long it takes before losing optimal psi range (1-2) as then increase/decrease the rate at which pump fills/drains liquid accordingly providing a better taste overall experience afterward!

If any changes are made throughout the course ensure they are updated in real-time on the tracking sheet so staff knows what values should be going forward – this provides accountability consistency between batches to boost overall quality assurance standards each time!

Final Tips

  • Always make sure there are no leaks anywhere in the tubing setup – tiny drops add up fast leading to higher-than-expected levels being reached if not careful – no one likes an explosion waiting to happen courtesy dodgy tap setup!
  • Start slow when adding CO₂ – sudden bursts could cause foam overflow resulting in wasted product further down line – always build up gradually so everything stays under control as possible without large amounts of time being taken up doing the same task over again due to poor planning procedures prior start filling stage!
