Espresso needs high pressure. We don't expect you to do this physically, so you'll have to buy a device. You'll also need a coffee grinder to guarantee the perfect taste.
Handheld Devices for Espresso
We've picked the three most versatile and straightforward devices for brewing coffee under pressure. They differ in the amount of pressure applied, the time taken, and the fineness of the required coffee ground.
The Traditional Moka Pot
Compared to other manual brewing devices, the Moka pot produces the highest pressure. This will ensure the closest results to the traditional creamy consistency.
The French press doesn't make espresso better than the Moka pot, but it's cheaper and faster.
Aeropress is the recent development of the French press. It uses the same technology, but it's faster because the coffee doesn't need time to steep.
Coffee Grinders: Manual Vs Electric
Pre-ground coffee beans lose flavor over time. Grinding on the spot gives you the desired "fresh" taste more than the type of coffee bean.
In terms of taste, the difference between manual and electric grinding is barely noticeable, even to professionals. However, manual grinders are cheaper, quieter, and more suitable for travelers because they're smaller and don't require electricity.
Due to their speed, electric grinders are more suitable for Espresso because the shots have to be pulled immediately after grinding. If you have to go for a manual, you'll compromise some of the coffee's aroma with slower grinding.
Coffee experts work by weight to ensure consistency of taste. But, it's up to you if you don't want to get that technical (or carry more tools).
