Precision in brewing lies in understanding how coffee strength settings truly work. Each adjustment alters the balance of flavour, aroma, and intensity in your cup. Brewmaster’s Elite emphasises that these settings go beyond simple preference, they refine the extraction process itself. Whether crafting a bold espresso or a delicate flat white, mastering strength control transforms ordinary coffee moments into rich, personalised experiences with consistent, barista-level quality.

What “Coffee Strength” Really Means?
In everyday conversation, strength often refers to how bold or intense a coffee tastes. However, on a coffee machine, the strength setting usually changes the coffee-to-water ratio, that is, how much ground coffee is used for each shot or cup.
When you increase the strength setting, the machine grinds more beans before brewing, which creates a richer, more concentrated drink. Lowering the strength reduces the amount of coffee used, resulting in a lighter, milder taste.
It’s important to note that this setting does not necessarily control the caffeine level directly. While a stronger brew tends to contain slightly more caffeine (because more coffee is used), it’s primarily the taste and extraction that are being adjusted, not the chemical potency.
How Strength Settings Affect Flavour?
Every coffee bean contains hundreds of flavour compounds, released during extraction when hot water passes through the grounds. The strength setting influences how many of these compounds end up in your cup.
-
Low Strength: Using fewer grounds makes the coffee taste lighter, cleaner and sometimes more acidic. This can work beautifully for delicate single-origin beans with floral or fruity notes. However, set too low, and your drink might taste watery or under-extracted.
-
Medium Strength: Often the “default” balance, enough coffee for a pleasant body and aroma, without overwhelming bitterness. This setting suits most everyday blends and milk-based drinks like lattes or flat whites.
-
High Strength: More grounds mean a denser, bolder shot with pronounced chocolate, nutty or smoky flavours. It’s perfect for espresso lovers or anyone who enjoys a more robust taste. But push it too far, and you may cross into bitterness if the extraction becomes too concentrated.
-
Think of It As Seasoning Food: Too little and it’s bland, too much and it’s harsh. The strength control is your way of adjusting the “flavour seasoning” of your coffee.
How Machines Adjust Strength?
Different machines achieve strength changes in slightly different ways. Understanding these processes helps you avoid common coffee machine mistakes that can affect flavour and consistency. Here are the most common methods:
Grind Volume Adjustment:
Most bean-to-cup machines simply vary the quantity of beans ground for each drink. Increasing strength means the grinder runs longer, producing more coffee to brew with.
Brew Time or Water Volume Adjustment:
Some models tweak the amount of water used instead, keeping the coffee dose constant but changing how long water flows through the puck. Less water means a more concentrated shot, more water dilutes the flavour.
Pre-Infusion Control:
Advanced or premium machines adjust pre-infusion, the brief wetting of coffee before full extraction. Longer pre-infusion can bring out deeper flavours and make a “strong” coffee smoother and rounder.
Knowing how your specific model handles strength is vital. Check the manual or experiment by weighing the coffee before and after brewing, you’ll soon see which variable changes.
Matching Strength to Bean Type and Drink Style
Not all beans or drinks benefit from the same strength level. Here’s how to choose:
- Light-roasted beans often have subtle, nuanced flavours that shine at medium or low strength. Pushing them too hard can make them taste sour or overly bright.
- Dark-roasted beans are naturally more intense and can handle higher strength settings without tasting bitter.
- Milk-based drinks such as cappuccinos or lattes often need a higher strength to cut through the creaminess of milk.
- Black coffees taste best at moderate strength, allowing the coffee’s natural sweetness and acidity to come through.
Experimentation is key. Small changes can make big differences, especially with freshly roasted beans.
The Caffeine Myth
Many people assume that turning up the strength gives them a much bigger caffeine boost. In reality, caffeine extraction depends more on the type of coffee and brew time than the machine’s strength setting.
For example, a double espresso made with a high-strength setting might contain around 120 mg of caffeine, while a large cup of filter coffee brewed at lower strength could easily exceed that. If caffeine is your concern, or you’re looking to boost health through moderate, mindful coffee consumption, look at portion size and bean variety rather than relying solely on the strength control.
Getting the Best from Your Strength Settings
Start in the Middle:
Begin with the default or medium strength and adjust one step at a time. It’s easier to detect improvement gradually than to jump from mild to overpowering.
Pair with Grind Size:
If your machine allows grind adjustments, balance both settings. A higher strength with a fine grind can over-extract; pairing it with a slightly coarser grind often gives a smoother result.
Taste and Record:
Treat it like a mini tasting session. Note which strength levels pair best with different beans and drinks. Over time, you’ll build a personal “coffee profile.”
Consider Water Volume:
For long coffees, lowering strength while maintaining a larger water output can preserve balance. For short drinks like espresso, increase the strength and reduce water.
The Beauty of Customisation
The joy of modern coffee machines lies in personalisation. No two people define “strong” the same way. One person’s robust, punchy espresso is another’s bitter wake-up call. By mastering your strength settings, you can tailor each cup precisely to your taste and mood, from a gentle morning brew to a bold after-dinner espresso.
So, the next time you adjust that little icon with the coffee bean symbols, remember: you’re not just making the coffee stronger or weaker. You’re fine-tuning the delicate balance of extraction, aroma, and body that makes every cup unique.

FAQs:
Does increasing coffee strength add more caffeine?
No. It changes flavour intensity, not caffeine. Caffeine depends on bean type and brew ratio, not perceived strength.
What’s the best strength setting for espresso?
Medium to high strength often works best. Test across several doses until you achieve a balanced crema and flavour.
Why does my strong coffee taste bitter?
Over-extraction or fine-grind texture can cause bitterness. Adjust grind or reduce extraction time.
Can I use decaf beans with strength settings?
Yes, you can. The same principles apply, the machine still adjusts dose and extraction for flavour balance.
How can I keep my machine consistent?
Clean regularly, descale every few months, and use fresh beans. This keeps the brew strength stable.
Should I change the strength for milk-based drinks?
Yes. For lattes or cappuccinos, a higher strength prevents the flavour from being diluted by milk.
