The essential components of excellent espresso, medium or medium dark roasts are perfect for making espresso...
It is critical both to choose the right coffee bean blend and grinding your beans to the proper consistency with richness, acidity, and brightness.
If the beans are ground too coarsely, the resulting coffee will be too watery and bitter. If the beans are ground too finely, no coffee will be produced due to a clogged filter. When the portafilter is properly ground and packed, the pressure required to produce proper crema is created. The espresso will trickle through it like honey dripping from a spoon.
The proper grind varies slightly between machines. Recommend grinding until slight granules are visible and the ground coffee packs tightly but does not cake when pressed between your thumb and index finger.
For typical home grinders such as Krups, recommend grinding small amounts at a time and experimenting with different grind settings until you find the one that works best for your machine.
The quality of your espresso machine will play a significant role in determining the quality of your coffee, as it contributes to two other critical factors: proper brewing temperature and pressure.
A properly prepared espresso should have a concentrated, sweet coffee aroma and a thick, foamy, cocoa-colored crema.
Use 6–8 grams of ground beans per 1-1.5 fluid ounce for a single shot. 15 grams of ground beans per 2 fluid ounces for a double shot. A single or double shot should take between 20 and 30 seconds to brew.
Grind between 18–21 grams of coffee into your basket for a double shot. It may be necessary to slightly adjust its fineness which is critical to producing a balanced, delectable shot of espresso.
In this case, the finer the beans are ground, the more caffeine they release into the water. In terms of caffeination, a finer grind produces a stronger cup of coffee, whereas a coarser grind produces a weaker cup.

OCM (OnCoffeeMakers.com) was started in 2007 with the first webpage about coffee machines. And for a number of years, we focused on helping people find their desired coffee machine (we still are helping folks with that! So, if you are looking for coffee machines for office or restaurants - check out the link).
In 2010, we started getting enquiries on restaurant marketing and we start to help food and beverage brands with their marketing. Below are campaigns and events that we have done over the years:

Check out this restaurant marketing guide to learn more about the many campaigns and companies we have worked with.
Since then, we have also created many marketing workshops and classes for the F&B industry. Many of these modules are still running in tertiary institutions such as Temasek Polytechnic Skillsfuture Academy and also ITE College East COC classes, below are some snippets of our lectures and workshops:
