- Pouring water slowly from a height results in a better coffee extraction
- The researchers found that pouring in this way mixes and shakes the particles
- The technique can give the same flavor with fewer coffee beans.
Researchers have discovered the secret for the tastier and well -rounded coffee without using additional beans, and is the simple swan neck kettle. This type of teapot has a long and fine nozzle, which produces a current of water with greater pressure and with greater controlled precision that is the key to a better beer.
Coffee prices have triggered in recent months due to factors that include climate change (including severe droughts and frosts in Brazil) that leads to bad harvests, increased production costs and a greater demand for coffee worldwide. Obtaining the same taste of a smaller portion of beans is, therefore, great news for those of us who love to start the day with a cup of spill.
As reported by The Guardian, researchers from the University of Pennsylvania have discovered that pouring water slowly from a height creates an ‘similar to avalanche’ effect that results in a better mixture of coffee and water, increasing the contact time and the extraction of more compounds of the flavor of the land.
They suggest you try to reduce the amount of coffee you use by 10% and experiment with a dumping from different heights (up to 30 cm) to see the changes in the flavor profile.
Choose the appropriate kettle
There are many swan neck teapots, but I have a couple of particular recommendations. If you want a traditional teapot for the stove, the fellow ‘coffee and booth and tea tea is an excellent option.
The partner is known for his Premium Coffee Preparation team, and the coffee fellow Aiden Precision is the choice of many professional toaster, including my specialized coffee association instructor (SCA).
Its closure boiler comes in two versions: Stovetop and Electric. The Stovetop version includes a thermometer with a dial at the top that shows when the water has reached the optimal elaboration temperature.
In contrast, the electric version has a temperature control that can be established in 1 ° F increases.
The Dualit 92960 Pour-Over Kettle is another great option if you are in the United Kingdom. It also has variable temperature controls and a retention function that maintains water at its preferred temperature for up to five minutes while weighing and grinding beans. It is a little cheaper than the electric swan neck bitch of colleagues.
