Best espresso descalers

In hard water areas this can happen at an alarmingly quick rate. Continue reading Best espresso descalers

Pour over coffee

A Complete Guide To Pour Over Coffee

As a coffee lover or expert brewer, you might have noticed the increasing buzz over pour over coffee, and you have probably been wondering what it is.

I remember watching in awe as my barista slowly poured water from a strange looking kettle with a long spout, into a bed of ground coffee placed in a little funnel-like device and I wondered why he was taking so much time to make a simple cup of coffee. He turned making a simple coffee into a ritual.

Impressed by the amount of time and finesse he used on this particular cup, I decided to look further into pour over coffee. When I took a sip of the coffee, I understood why it was clean and fresh – a revolution. Now I find myself brewing my coffee with my brand new pour over cone every other day at home.

Descaling an espresso machine

If you live in a hard water area it is a good idea to descale your espresso maker frequently as the build up can eventually cause a blockage and descaling becomes incredibly hard.

A scaled machine makes poor coffee as flow and pressure are affected and in bad cases the heating element is almost ineffective.

Using filtered water can help to minimize the limescale build up.

Bear in mind that most descalers take around 20 minutes to properly work.

How often should you descale an espresso machine?

Hard water areas with 6 uses per day should be done monthly.
Soft water areas with 6 uses per day – every 3-4 months.

Hard water areas with 12 uses per day should be done every 3 weeks.
Soft water areas with 12 uses per day – every 2-3 months.

Some espresso makers have a special descale program where they pulse water through at regular intervals to keep fresh descaler on the heating element. Ideally this will take a full reservoir of water and take the full 20 minutes.

If you do not have an automatic espresso descaler option you’ll have to do it manually.

Don’t run extract hot water from espresso maker continually for more than  a few minutes – most are designed for occasional use and you’ll burn them out if you are not careful.

The aim is short bursts over 20 minutes. Heat is not important for most descalers but do read the instructions, some require heat and a few will react violently if heat is used.

  1. Remove the portafilter so you can see what is going on more clearly. Ideally water will pour from the entire outlet but as machines silt up you’ll often end up with a single or double jet. This is a sign your machine needs descaling.
  2. Pulse a short extraction through the machine until it comes out of the portafilter feeder and then shut the machine off and allow it to cool for 4 minutes.
  3. Then pulse hot water through the machine for 2 minutes and wait for 4.
  4. Remember to include the steam wand in the hot water pulses every now and then for a few seconds.
  5. Turn off the machine and allow to cool for 4 minutes.
  6. Repeat steps 2-5 until the water is running clear and from the entire water outlet or for at least 20 minutes.
  7. Flush the machine with two full reservoirs of water, in short 2-3 minute bursts.

If your espresso maker has a hot water option it is better to use this than continually run short burst through the portafilter. Switch the machine from time to time to flow through the portafilter and steam want to fully descale the machine.

 

Your machine is now ready to use again.

It helps to run a shot of water through the portafilter after every days use so it isn’t sitting overnight with coffee residue which will harden. Some users do this after every use but Coffee Revolution do not think this is necessary, unless it will be left to sit for a while.


A review of Pod coffee machines

When choosing a pod coffee maker there are so many to choose from. We would recommend taking a look at the various types of pods on offer and then choosing a machine based on that.

Personally we will always choose a ground coffee maker as there is more choice and you have great control over the amount of coffee in each shot and the tamping process, all of which influence the flavor. Continue reading A review of Pod coffee machines


Indonesian vs Greek vs Indian vs Turkish vs Italian coffee

Every part of the world has their own way of brewing coffee. Something I found very interesting is that in regions that are world renowned for their coffee quality, the bulk of people drink coffee in very “primitive” ways.

Most of the following are simply coffee grounds added to simmering or hot water and poured out. Continue reading Indonesian vs Greek vs Indian vs Turkish vs Italian coffee


Brewing greek coffee

A simple coffee using finely ground beans and prepared in a traditional stove top method is quite easy to make.

Use a stove top pan or Briki, and finely ground coffee. For our Greek coffee we prefer to use Brazilian Santos or Java beans. Typically Arabica grown in the milder lower part of the coffee belt gives ideal tasting notes for Greek coffee. Continue reading Brewing greek coffee

In the United States, the daily consumption of espresso based beverages has tripled since 2008, with a 45% increase in third-wave branded coffee.

Instant vs fresh coffee

While many coffee aficionados tend to stay away from instant coffee, it make up around 13% of all coffee consumed.

First invented in the 1770’s in Britain, instant coffee wasn’t able to easily be produced in mass quantities until much later in 1910, when the instant coffee business started to really take off.

There are two main ways that instant coffee is produced, the first uses dry hot air to absorb the moisture in the coffee, and the other uses a freeze drying process. Continue reading How Instant coffee is produced

The Truth about “Naturally Decaffeinated Coffee”

This might conjure up images of obliging coffee plants producing caffeine free beans or coffee producers tempting the caffeine out of the coffee beans with videos of baby pandas sneezing.

The truth has rather more to do with clever industrial processes than with nature. Continue reading How is coffee decaffeinated


Coffee Pod vs espresso machines

Brewing coffee nowadays is about as easy it gets, with machines able to brew and pull espresso shots just by inserting a pod and pushing a button. But how do these pod espresso machines compare to more traditional espresso machines, in which the user grinds and tamps the coffee beans?

Which bar pressure espresso machine

When shopping for an espresso machine, among the millions of features advertised is the bar pressure rating of the machine, meaning how much pressure is used to force the water through the coffee grounds in the portafilter.

Bars are a measurement of atmospheric pressure, so one bar of pressure is equal to the amount of natural pressure at sea level, meaning 10 bars is 10 times the amount of pressure at sea level. Continue reading Which bar pressure espresso machine


10 espresso myths

Let’s take a look at some commonly held myths about espresso and put some facts out there.

1. What is the crema, and why is it so obsessed over?

Crema is the lighter cascading portion of an espresso shot, that slowly dissipates the longer the shot sits.

Crema is responsible for a ton of the espresso shot’s flavor, and is relied upon by those who make latte art. While striving to pull shots with perfect crema, there are a ton of variables that one should try to account for, such as the roast of the beans, how fresh they are, the kind of beans being used, and also the machine itself.

French press vs chemex

When comparing the French press and a Chemex, one of the only similarities between the two is the fact they both brew coffee. While their differences are substantial, their impact on the coffee world is just as much so.

Invented in the early 1900’s, the French press takes advantage of a full immersion style of brewing; meaning the coffee grounds and water are steeped together, as opposed to the water just passing through a bed of grounds. Continue reading French press vs chemex


Cleaning a drip coffee maker

Drip coffee makers come in all shapes and styles; from inexpensive models up to models up in the hundreds of dollars.

One thing these different machines have in common though, is that they need to be descaled and deep cleaned every so often to ensure the quality of coffee is always high.

If a coffee brewer isn’t cleaned, it runs the risk of negatively impacting the flavor of the coffee, or just flat out breaking if the heating element is clogged with hard water buildup. Continue reading Cleaning a drip coffee maker
