Slayer Coffee MachinesTaste your coffee again. For the first time.
Slayer was imagined, designed, and built for one purpose: to make coffee better by means of “flavour profiling”. In the past, Slayer Espresso, an experienced team of coffee roasters, equipment distributors, and baristas, observed significant differences in mouth feel, body, and sweetness when comparing traditional lever machines to the contemporary models coming out of Italy. Their palates favoured the older machines, and as such they set out to determine exactly how they extract coffee and why they liked it more.
The Evolution of the Slayer Coffee Machine
They learnt three things: first, before releasing the spring inside, lever machines slowly infuse the ground coffee in water. Blooming inside of the portafilter, the coffee releases gas and is prepared for extraction, similar to the first stage of pour-over brewing.
Secondly, and because of this slow infusion, lever machines require baristas to grind coffee finer. Which is a good thing as the greater surface area on each coffee particle the more of the oils therein are available for extraction. This results in coating the palate, which mask bitterness and reveals inherent sweetness.
Finally, the pressure applied by lever machine springs gradually decline during extraction, muting acidity. The resulting cup is sweeter and more viscous and here is the key to the modern day Slayer coffee machine.
