Fermenter King Junior 20L PET Pressure Fermenter Keg

Introducing the Fermenter King Junior 20L PET Pressure Fermenter, the compact pressure-capable fermenter designed for home brewers who want professional-level control in a space-saving footprint.
Made from high-strength, clear PET material, this fermenter allows you to visually monitor fermentation progress and pressure-ferment safely up to 35 PSI. Ideal for small-batch craft brews, ciders, seltzers, and experimental recipes.

The Fermenter King Junior includes stainless steel pressure posts, an integrated floating dip tube for clearer beer transfers, and a wide-mouth opening for easy cleaning and dry hop additions. Its sturdy base and lightweight design make it perfect for fridges, fermentation chambers, and portable brewing setups.

Pressure fermenting reduces ester production, speeds up fermentation, and enables direct carbonation and closed transfers straight to a keg without oxygen exposure. Better flavour, better clarity, and less equipment needed.
