BrewBuilt X3 in Action – From Fermentation to Packaging

Final part of our BrewBuilt X3 series — and this time we’re putting it to work properly.

Across this series we’ve looked at the BrewBuilt X3 from the ground up — build quality, features, and setup. This final video is where it all comes together, following a full brew from fresh wort through fermentation, handling, and packaging to show how the X3 performs in a real brewing environment.

Rob brewed this smoked lager for his appearance on The Hop Addition Podcast, making this a proper real-world run rather than a staged demo. If you’ve been considering upgrading your fermentation setup, this is the practical, brew-day-to-glass view of what the X3 actually enables.

What This Video Covers

– Casting wort into the BrewBuilt X3
– Setting up and managing temperature control in a real brewing scenario
– Yeast dumping and trub management using the conical design
– Pressure-capable fermentation setup
– Closed transfer from fermenter to keg
– Packaging into bottles and cans using the Duofiller / Cannular system
– Transferring into Oxebar kegs
– Fermentation considerations for smoked lagers

From Fermentation Control to Full Workflow

The key shift with the BrewBuilt X3 isn’t just stainless construction — it’s moving into a more controlled, repeatable brewing process.

In this video, you can see how temperature control is applied in practice, not just discussed. Holding a consistent fermentation profile, particularly for lager styles, makes a noticeable difference to the final beer.

The conical design also allows for proper yeast and trub management. Being able to dump sediment without disturbing the beer is a simple upgrade on paper, but in use it keeps fermentation cleaner and reduces handling.

Pressure-capable fermentation builds on this further, opening up faster turnaround times and giving more control over flavour profile — particularly useful when brewing clean lagers like this smoked example.

Closed Transfers and Oxygen Control

One of the biggest improvements comes once fermentation is complete.

The X3 allows for fully closed transfers into kegs, reducing oxygen exposure at a stage where beer is most vulnerable. In this video, we transfer directly into an Oxebar keg, showing how a low-oxygen workflow looks in practice rather than theory.

For anyone brewing hop-forward styles or delicate lagers, this is where noticeable quality gains start to appear — better shelf life, fresher flavour, and more consistent results.

Packaging with Cannular

From keg, we move into final packaging.

Using the Cannular system, we demonstrate bottling and canning as part of a closed, oxygen-conscious process. This ties the entire setup together — from fermentation through to packaged beer — without breaking the chain.

It’s a good example of how the X3 isn’t a standalone piece of kit, but part of a wider system that supports better handling throughout the brewing process.

Putting It Into Practice

If you’re currently fermenting in plastic buckets or glass, the jump to a system like the BrewBuilt X3 is less about complexity and more about control.

This setup allows you to:

• Maintain stable fermentation temperatures
• Manage yeast and trub cleanly
• Ferment under pressure when needed
• Transfer and package with minimal oxygen exposure

Combined, these are the steps that move your brewing from “good” to consistently repeatable.

If you’re looking to build a more complete fermentation and packaging workflow, the BrewBuilt X3, Oxebar kegs, and Cannular system are designed to work together as a joined-up solution.
