Read this blog post to learn more about under-extraction espresso machines so you can avoid wasting money on equipment that doesn’t work for you!

Espresso machines are an integral part of the coffee shop scene in many parts of the world; however, not many people know how to operate them properly. If espresso is under extracted, it can be unpleasant and unenjoyable to drink.

In this blog post, we will discuss what causes espresso to be under extracted as well as ways you can fix the issue so that your cup of Joe is more to your liking!

Under extraction occurs when not enough water passes through the coffee grounds in a given amount of time, often resulting in a thin, watery cup of coffee. This happens when there is not enough crema on top, which is an indication of a good shot.

Crema is important because it contains emulsified oils from the beans that give espresso its distinctive taste and aroma. When extraction is too short or there isn’t enough pressure on the water as it’s being pushed through the grounds, an under extracted shot can occur.

What to do if espresso is under extracted?

If you are getting less espresso than you would like, one thing you can do is to use the right amount of beans. Use about double the weight of beans as water. You can also try grinding your own coffee at home using a good-quality coffee grinder.

How do you tell if espresso is under or over extracted?

Under-extracted espresso may look darker than it smells or tastes, and may not have an astringent quality that some people find desirable. You can try recirculating the water through the fine coffee grounds to achieve the desired flavor.

Since extraction is about 12-14% on average, you can try adjusting your grinder by 8-12% of coarser particles to hit your desired target.

Over-extracted espresso is less dark, has a more acidic taste, and tends to be very bitter with a strong astringent aftertaste.

This type of extraction comes from using too much pressure when extracting through espresso machines ranging from 9 bar on up…or if you are grinding finer grounds for some reason. Try upping your bean coffee weight, or using a coarser grind for your espresso!

How does under-extraction affect the taste of my drink?

An extraction that is too short may produce an unpleasant bitter flavor. If you are wanting to get more caffeine per cup in order to feel energized, this might be great for you! However, if you are looking for a more traditional espresso flavor, you will likely be disappointed.

Under-extraction can also produce a thin, watery cup of coffee. This happens when there is not enough crema on top, which is an indication of a good shot.

Crema is important because it contains emulsified oils from the beans that give espresso its distinctive taste and aroma.

If espresso is under-extracted, what should you do?

If under-extraction is the issue, you may need to try a coarser grind. Get your beans in form of whole bean so they are fresh when grinding them yourself. You can also use more coffee in order to get stronger espresso!

  • Use the right amount of beans: about double the weight of water.
  • Grind your own coffee using a quality grinder.
  • Recirculate the water through the grounds to achieve the desired flavor.
  • Adjust your grinder by up to 12% coarser particles to hit the desired target.
  • Enjoy an unpleasant bitter flavor.
  • Get less caffeine than you would like a per cup.
  • Produce a thin, watery cup of coffee.
  • Have an extraction that is too short.

Espresso machines that produce over extracted shots tend to be less flavorful and have less crema on top because there isn’t enough pressure on the water as it’s being pushed through the grounds.

It often tastes watered down or bitter rather than strong with a good mouthfeel from the oils present due to proper extraction times. If this problem occurs for whatever reason, consider using finer ground coffee…or perhaps switching up how much water you’re using as well as changing your filters if possible!

Importance and Use of Espresso Tampers

An espresso tamper is a tool used to compress the coffee grounds in an espresso machine’s portafilter.

If you’re just starting out, it might be a good idea to buy a basic tamper until you figure out what you like. There are also many tutorials online that can help you learn how to tamp like a pro.

When do I Adjust the Grinder?

If your espresso is consistently over or under extracting, you can try to adjust the grind size. If it’s consistently over extracting, try increasing the grind size by a few notches.
