The crema is the best part of an espresso. What is crema? Why is it important for coffee drinkers? How can you achieve the best crema in your espresso shots?

The rich caramel color of espresso coffees is well-known to all coffee lovers, whether they are served with milk or black. Some espresso lovers may be aware that a barista quality crema is essential, but many don’t know how or why. Like most foods, the secret to a great crema is using a quality recipe and good ingredients.

What is crema?

The beautiful, and hopefully familiar, golden foam head is composed of coffee oils aerated with acids and sugars. A well-extracted espresso shot will have a balanced mixture of these key ingredients. The best parts of the coffee will dissolve in water if you apply enough pressure and heat. The amount of solubles released by different brewing methods can produce different flavors and caffeine levels. Each method caters to individual preferences. When it comes to espresso, we want to extract a certain amount of solubles. Using the right techniques and fresh coffee beans will be the winning recipe.

Why is cremation important?

Crema is a very important indicator of the quality of an espresso. It shows how well you extracted the coffee oil, sugar, and acid. The crema in espresso is responsible for 70% of its flavor. It should contain around 18-22% of coffee (the remainder being water).
Good crema is around 5mm in thickness and has a golden, dark caramel color. The crema should have a mixture of lighter and darker shades. Each part of the shot releases different solubles as it runs, which can vary in color. When making a ristretto, the change in color and ingredients, while an espresso shot is pouring are the most obvious.

How do you get the best crema for your espresso shots

It is possible to achieve the perfect crema every time with a few key components. It’s all about ticking the right boxes!

* How to buy freshly roasted beans

As with all great food and drink recipes, success begins with fresh, high-quality ingredients. FSANZ (Food Standards Australia New Zealand) considers coffee to be a fresh food, and it should be treated and purchased as such. This means buying fresh roasted coffee beans from your favorite coffee roaster. Roasters withhold beans for at least five days after roasting to give the flavors time to develop. This means that consumers have only a maximum of 4-5 weeks in which to enjoy their coffee. Never buy coffee beans without a date for roasting them.

* How to store your roasted coffee beans

To get the most flavor and shelf-life out of your beans, you must store them just as you would fresh food. As with other food products, coffee beans are also affected by environmental conditions. Moisture, ultraviolet sunlight, heat, and oxygen are all environmental factors. When not in use, it is important to store them in an airtight, cool, dark, and dry place.

* Grind your coffee beans freshly to order

When you grind a coffee bean, similar to squeezing a citrus fruit peel, many of the aromas and solubles will be released within seconds. This increased surface area will either allow the key ingredients to escape or begin degrading rapidly, depending on what it is. It is important to brew your coffee immediately after grinding it. The longer you wait, the more ingredients will escape.

* How to make the perfect cup of coffee

The key to producing the perfect espresso is using the right techniques and controlling variables. This will ensure that you get a thick head of crema at the top. It is best to gain experience making espresso. This will improve your muscle memory and consistency. You will also learn how to judge if you are getting good shots based on visual clues. Use other tools such as scales, calibrated tampers, and timers to make the process easier.

* Brewing machines and equipment of high-quality

Quality brew equipment and gear becomes important once you’ve mastered your technique. You use freshly roasted beans and grind them each time you brew. It isn’t easy to know the difference in quality when you are a novice barista. But as your skills improve, you will notice if your equipment is of high quality.

* Get training

We can help you if the idea of figuring it out all on your own is making your eyes squint and your head hurt. We run an Espresso Essentials course. Come and speak to us. This class is often called the Home Barista Class because it is designed for those who want to learn to make great coffee and care for their equipment and beans at home.

What happens when you grind your coffee beans?

After a coffee bean is crushed or ground, a number of chemical reactions continue. This can have a negative impact on the coffee’s flavor and performance. That is why it is best to grind fresh when you order! Four main processes are involved in this.

* Oxidation
When some materials come in contact with oxygen, they can undergo this process. Coffee oxidizes in the same way that steel rusts and bread turns stale. Avocados also turn brown. If coffee is exposed to oxygen for too long, it will develop a bland and funky taste.

* Moisture
The moisture content of coffee beans is reduced to about 3-4%. They are highly absorbent and similar to rice. The coffee will absorb any moisture it comes in contact with and will dilute the precious water-soluble oils. The water molecules can absorb aroma and flavor compounds, contaminating your product.

* Contamination
When roasted coffee is left in its ground form, it can absorb foreign compounds that are floating in the air. These compounds can be anything, from food odors to cleaning chemicals and perfumes. Just like foreign compounds can get in, precious coffee ingredients like CO2 can get out.

* CO2 Absorption
Throughout their shelf-life, coffee beans slowly lose gasses. Gases (mostly CO2) are used to transport our acids, sugars, and oils. It isn’t easy to get good coffee solubles through the water without a gas. The gases will escape almost instantly when the coffee is ground, which reduces flavor very quickly.

Why you should purchase a coffee grinder for your home

It’s clear to see that it is important to be able to grind your coffee beans as you require them. Here are a few of the many reasons why you should do this:

* Better coffee quality
The best coffee is made by grinding your beans as soon as possible. This will ensure that you are extracting the maximum amount of coffee solubles while minimizing coffee degradation due to time and environmental factors.

* Extended coffee shelf life
Keep your whole-bean roasted coffee beans until you’re ready to use them to extend their shelf life up to 6 weeks. Coffee that has been ground usually has a shelf life of 10-14 days before it starts to taste bland or bitter.

* Flexibility when brewing
You can make changes in the way you work by having your grinder.

– Switching between different brewing gear
You can switch between different sizes of grind if you have more than one brewing method at home, such as cold brewing and espresso. You may be able to use the same coffee bag for multiple methods depending on the blend of coffee you are using.

– Grind as much as you want
You can extend the shelf-life of your beans by grinding only the amount of beans you need. The majority of the beans can be left whole, and you can brew freshly ground coffee right away.

– Making grinding adjustments
This option is essential if you are making espresso. Espresso machines need to be adjusted regularly to ensure the best crema and coffee. You can experiment with different grind sizes, regardless of the equipment you use. Some people like a finer grind for their French press coffee compared to what we recommend – everyone has a different taste!

What is the best coffee grinder?

You will find that there are many options and information available if you look at the grinders online or in a store. We recommend that you speak with a coffee expert and use their experience to navigate the crowded market of coffee grinders. We have a showroom at Crema Coffee Garage where you can test all of our grinders. Our highly-trained machine specialists will guide you and answer any questions you may have. Before you start looking for a coffee grinder, it is important to consider and decide a few factors. These will help you narrow down the options:

* What type of coffee do you brew
There are different grinders that you can choose from depending on what type of coffee brews best. If you make cold drip or pour-over coffee, you don’t need to use a super-fine grinder. These grinders are built differently than those for espresso machines and may be cheaper. You may want to choose a grinder with the flexibility to brew anything you like.

* How many coffee beans do you need to grind
If you grind in large quantities or batches, you will need a different grinder. This is what we call a batch or alternative brew coffee grinder. If you want to grind a 250g bag of cold brew coffee, a hand grinder might not be the best option. Hand grinders or electronic espresso grinders work well for small amounts.

Your budget for a coffee grinder
After you’ve decided which style of grinder is best for you, it’s time to determine what you can afford. Each grinder will have a different price. This is why it’s important to visit a local expert. You can find grinders that are surprisingly good for a low price. Only your local coffee expert will know which ones they are.

Where to Buy a Home Coffee Grinder

There are many places where you can buy coffee grinders, online or in-store. Be sure to check that the website or company from which you’re buying is reliable and, if possible, located in Australia. It will make it easier to send and receive packages and provide customer service when needed. You can find reviews online of both the company and the grinder you plan to purchase. Buy online only if there are clear warranties and return policies.
