Coffee Roaster and Coffee Equipment Supplier
Qualitasse was founded in 1982 where it started out as one man, Brian Layton, selling filter coffee machines and coffee from the boot of his car. Fast forward and the business soon had premises (circa 1985), then larger premises (circa 1992), then a water cooler business was established (maybe 1998?) and at the same time espresso machines where being supplied and maintained alongside bean-to-cup machines, then the first coffee roaster was installed (probably around 2005), then a takeaway cup making machine started producing compostable takeaway cups (definitely 2022) ! Below we give an in-depth profile of one of our main specialities – coffee roasting – for which we are multiple award winners!
Coffee beans are the seeds of the cherries of the coffee tree, each cherry typically contains two beans whose flat sides face each other.
When steeped in hot water, raw or “green” coffee beans offer little in the way of what one might relate to as coffee taste and aroma.
Roasting green coffee creates a chemical change; the production and breakdown of many compounds and obviously the roaster helps. This in turn creates development of beautiful flavours when the beans are ground and steeped in hot water.
Some of the many effects roasting has include;
Change in colour from green to yellow to tan to brown to black (a step too far!)
Nearly double in size
Become half as dense
Gain and then loose sweetness
Become more acidic
Develop hundreds of aroma compounds
Pop loudly as they release pressurised gases and water vapour
The main goal of roasting is to optimise the flavours of coffees soluble profile as dissolved solids make up the brewed coffee taste.
