Our roasters: The reason our coffee tastes great - Part one

At York Coffee Emporium we use three different types of roaster to make sure our beans are always roasted to perfection, and freshly to order. Each roaster is a different make and model and they’re all from different countries, which means they all roast differently. The machines most definitely have their own character and personality -- you really need to bond with them to get the best results!

OUR ROASTERS

Our three roasters are:
Coffee-Tech Engineering Solar Automatic electric drum roaster
STA Impianti vintage manual gas drum roaster
Sivetz ¼ bag fluid bed gas air roaster

In a series of blog posts we’re going to give you the lowdown on each roaster, starting with...

SOLAR AUTOMATIC ELECTRIC DRUM ROASTER

Most roasting machines use the drum roasting method, where heat is applied to a rotating oven. The green beans are fed in and roasted using conduction, radiation and a little convection. And this is exactly how the Coffee-Tech Engineering Solar Automatic works.

It’s fully programmable and we use it to roast the small batches required for our online orders. This means every single order is genuinely freshly roasted and hasn’t been left around waiting to be sold. It works best roasting small batches of around 1-2kg and will roast even the most difficult beans.

CORRECT ROAST PROFILE

When we’ve ascertained the correct roast profile according to the coffee type (this involves working out the optimum time, temperature and airflow in the roasting process), we can simply select it on the roaster and it automatically follows the programme. We just then need to monitor the process and intervene at the correct points to achieve a consistent roast and taste.

FLEXIBILITY AND CONTROL

With the Solar, Coffee-Tech Engineering pride themselves in offering “unprecedented flexibility in producing quality, unique coffee... with total control over the final product, the ability to repeatedly produce the same profile time and again...”. We pretty much agree with this, however, as coffee beans are subject to inconsistencies, it’s still vital to keep a close eye on the roast and intervene if necessary.

A GREAT LITTLE ROASTER!

Simply put, we love this roaster - it gives great tasting coffee and can produce the clean, fresh tastes we expect of South and Central American beans, while also coping with the characterful anomalies found in Indonesian and some African beans.
