Manufactured by Krups, a brand notable for its coffee machines, the Sub is a compact, tabletop version of what you would find in a pub or bar. You can separately buy 2L kegs that slot into the machine or buy Sub and keg bundles.
The Sub keeps beers chilled at a constant temperature of 2-degrees Celsius, and you can store the keg inside the machine for up to 15 days. We loved the Sub in our review, where it received 4/5 stars.
Beerwulf, a subsidiary of Heineken offers two sizes, including a fully Heineken branded option made of aluminum, now reduced to £129 from £199 (£70 off).
The full-sized Sub weighs 6.8kg and loads kegs from the front, while the smaller and lighter Sub Compact weighs 4.45Kg and loads the keg from the top. The Sub Compact now has £30 off, dropping the price to £99. Both machines plug into the power mains.
