เทคนิคเลือกเครื่องทำกาแฟสำหรับมือใหม่ คุ้มค่า คืนทุนไว ใช้งานคุ้ม

Most coffee entrepreneurs would focus on the store location or the main coffee bean that would be used to make coffee when investing in their coffee shop, but one of the significant factors that they might over look is purchasing the suitable coffee machine that has the necessary functions for the store without learning about the specifics of the coffee machines. Apart from the coffee machines, there are also other equipment that are essential as well such as, coffee grinders, accessories for coffee brewing, containers, and different ingredients for each menu that the entrepreneurs should have in their coffee shop.

However, the main issue of those that are at the beginning of starting their coffee shop would be the suitable coffee machine selection that would be best for their shop, which is considered an important investment as coffee machines are very expensive. Purchasing 1 coffee machine is a long term investment so buying one means that you must use it for a couple of years. Therefore meaning that you should learn about the specifics and details before deciding while also considering carefully about the efficiency, functions, materials, along with after services as the coffee machine is not only expensive but also relates to the coffee’s flavors, amount of coffee serves per day, and also the customer’s decision of purchase.

Today, Boncafe would like to lead you into the survey methods for entrepreneurs oท purchasing a coffee machine along with the principles and factors that they should take into consideration before making a decision.

Before that, we would like to introduce you to the main categories of coffee machines which can be categorized into 3 main groups:

1. Espresso Machine 
2. Capsule Machine
3. Automatic Coffee Machine

Espresso Machine is the coffee machine commonly used in the coffee business industry with various semi-automatic functions such as coffee extraction, hot water, or milk frothing.

The Espresso Machine might have more functions than the hotels’ automatic coffee makers or the automatic vending machines in department stores but the Espresso Machine provides us with quality coffees along with the most desired coffee flavor, which will depend on the barista’s experience, coffee bean ingredients, and the machine’s pressure as the coffee extraction or known as espresso shots will rely on extraction pressure and water temperature as the important factor of the coffee’s flavors.

So how do we know the suitable amount of pressure to use in extracting the best coffee as each coffee machine has different pressure specs and how does each pressure bar affect the coffee’s taste?

Pressure is extracting coffee by force with hot water. The espresso machine’s best pressure would be 8 to 10 bar (baristas would set at 9 bars as standard) but if you use more than this would cause the coffee beans to be too extracted; resulting in the harsh, bitter, and burnt flavors or called “over extraction”, quite like speeding up the coffee’s extraction process and ruins its best flavor.

Moreover, the hot water temperature that is used to extract coffee should be at 92 °C. If more than that, the coffee flavor would be too strong; might cause it to taste bitter and burnt. At the same time, if the water temperature is too low, the extracted coffee will taste bland, harsh, and have less coffee body.

However, the coffee’s flavors might not solely depend on the hot water’s temperature but also from other factors as well like the coffee breed, roasting degree of the coffee bean, or the coffee bean’s grinding textures.
