The straight answer to this is no.
The requirement to produce the very best brewing and extraction rate is a science and very few coffee manufacturers take note of this. Kenwood machines observe the precise measurements required to product the coffee of your choice to its optimum extraction ensuring that you get the very best coffee drinking experience.
Some of these key factors are:
• Using fresh water
Filter coffee is 98% water so using fresh water is essential to the quality of your coffee. You should consider using filtered water which will also reduce the risk scale build up in your machine.
• Using the correct coffee grind
If grind is too small then water will pass through too slowly causing over extraction, coffee will taste bitter and thin. On the other hand if the coffee grounds are too large water will pass through too quickly and under extract, coffee will taste flat and weak.
• The right amount of coffee
To ensure that you brew a balanced cup of coffee you should use the correct proportion of coffee to water. More or less will result is a stronger or weaker coffee.
The ideal ratio is 60g per litre of water. Typical 10 cup machine at 1.25litres will require 75g of coffee.
• Correct brewing temperature
The best temperature to brew coffee is between 92-96°. Too cold and the aroma compounds will not be extracted you won’t extract the full flavour of the bean. Too hot and over extracting will cause a bitter, astringent taste.
Filter coffee machines use either and glass or thermal carafe. The glass carafe uses a hot plate to keep the brewed coffee warm whilst the thermal will retain the coffee brewed temperature through insulated walls.
There are benefits and drawbacks that outweigh each option.
It is said that the hot plate used on the glass carafe will cook the coffee over time tainting the freshly brewed taste.
The thermal carafe retains temperature better but is often more expensive than the glass option does not enable you to see exactly how much coffee is inside.
The type of coffee is dependent on your own taste, Typically Arabica beans are better and more flavoursome than Robusta.
However, the best coffee in the world will not taste to its fullest unless you obverse the points above (see question 4)
Generally espresso and filter coffee
Coffee is such a versatile produce that it can be consumed in a various ways. Some of the most popular choices are based with milk and espresso coffee.
Cappuccino is one part espresso, one part steam milk and one part frothed milk. Latte is one part espresso and two parts steamed milk.
Most espresso machines have a steam function to aerate milk required to make frothed milk. In order to make a latte simply keep the steam wand submerged to the bottom of your frothing vessel; this will draw in less air and create less froth. Do the reverse if you require frothier milk.
Pod machines or single serve are typically closed system (dependent on a particular system) using pre-portioned doses of coffee either in capsules, discs or pods (like tea bags).
The regulation of water and dose of coffee is usually preset which can limit you’re the strength and length your drink. Pods though are easily discarded and easy to use with offers the consumer added convenience over loose coffee.
Espresso has one thing in common with filter coffee that being the bean but that is where their similarities end. Espresso is a concentrated coffee, extracted with pressured water forced through very finely ground powder.
The result is small cup of coffee with a rich consistency, bittersweet taste and golden froth on top known as crema.
It requires a minimum 9 atmospheres of bar pressure to extract the fuller flavour from espresso.
Filter or drip coffee is made by hot water passing through ground coffee. Hot water is filtered solely under the pull of gravity. When water comes into contact with ground coffee, the flavours, colour and aroma from ground coffee are extracted and dissolved in the water, this is known as extraction.
