The Best Way To Train Your Palate

One of the most important assets for any coffee professional is his/her palate. Without a fine-tuned palate and sensory skills, it is almost impossible to know what you are tasting or smelling, much less describe it to others. How then does one go about training and refining their palates? We ask some professionals from around the industry to find out what they do or think is the best way to train their palate.

Hot or Cold? The Best Temperature for Brewing Espresso

For the past few decades, temperature stability has been a major goal for many espresso machine manufacturers and also one of the deciding factors of the quality of an espresso machine. There is without a doubt, a huge emphasis placed on temperature in the brewing process of espresso. So how exactly does temperature affect espresso and the brewing process? What is the final impact on the extraction of the coffee when brewed using different temp..

Putting it together: Pre-infusion on a low overall brew pressure

We've tested different brewing pressures, we've tested different pre-infusion timings and pressures; now it's time to put them all together! These days, we pull our espressos with a pre-infusion between 9-16s and full brew pressure at 7 Bars at the shop. Does pre-infusion at this lower brew pressure setting make a difference in extraction percentages? Or will it prove to be equally insignificant as compared to the standard brew pressures?

Pre-infusion and it's impact on espresso

This week we will take a look at pre-infusion (pre-brew) and it's result in the espresso. Pre-infusion can come in many forms, from soft infusion to hard infusion to variable pressures and different lengths of time. We will be testing multiple pre-infusion techniques over the coming weeks but first, let's define some of the different pre-infusion variables that are commonly used in the coffee industry.

Espresso Brewing Pressure: Is 9 Bars really optimal?

Almost all semi-automatic espresso machines are calibrated and set by default to brew at roughly 9 bars of pressure. Lucky for us, we use the Slayer espresso machine, one of the few espresso machines out there that allows for easy tweaking of the brew pressure. This week, we will be setting out to test the impact of brewing pressure on the resulting espresso and it's extraction percentage.

Levy Tamp vs Pergtamp

Tamping is one of the crucial steps to espresso preparation. Last week, we set out to test two different aspects of tamping; the levelness of a tamp, the tamper's base size and their effects on the resulting espresso. If you haven't already read it, you can check it out below! This time, we are doing a direct comparison between the Levy Tamp and the Pergtamp.
