What does the strong button do on a Keurig

Although Keurig coffee makers are incredibly convenient, they are often criticized by coffee snobs for brewing weak or watery coffee.

To counter that, Keurig started incorporating “strong brew buttons” in their latest models, especially the higher-end ones.

So, How does the strong button work in a Keurig?

Keurig’s strong button actually slows down the brewing process by adding 30 extra seconds, thereby increasing the amount of time the coffee grounds are in contact with the water. This prolonged extraction process actually makes the coffee taste stronger.

The craving of coffee enthusiasts doesn’t end with a weak cup of coffee that’s why a strong brew function in a coffee maker is important and Keurig understands it.

Does strong button on Keurig really brew a strong cup of coffee?

It’s a fact that Keurig doesn’t brew the strongest coffee, but rather simple and smooth coffee with much convenience and speed.

But does Keurig really brew a strong cup of coffee when you press the strong button?

Yes, It does! I have tested and used many drip coffee makers in my life. Strong button on other coffee makers doesn’t make much difference, but in Keurig, I can definitely say it makes a difference and strengthens the coffee. I think it’s because normal Keurig brew is too weak and a little extra extraction time actually adds flavors that are noticeable.

I believe Keurig’s coffee is only acceptable when the strong button is pressed, otherwise, it is too watery. In my opinion, Keurig coffee makers without the strong brew button are worthless, at least to me.

Keurig brewing systems are quick and brew coffee within 40 seconds after pressing the button. This brew time isn’t long enough to extract all flavors from the coffee grounds, when you press the strong button, the brew time is extended to 70 seconds and that results in better extraction of flavors.

How longer brew time makes a strong cup of coffee?

In general, the longer the contact time between water and coffee grounds, the more flavors will be extracted and the drink will be stronger.

During extraction, acidic flavors are extracted first, that is why you might have noticed that Keurig’s normal brew is acidic.

The bitter and sweet flavors of coffee grounds begin to extract after that, which is why Keurig’s strong brew has a more balanced flavor profile with all the flavor notes of coffee.

In general, coffee strength refers to the amount of solids dissolved in the water, and as water contact with the grounds increases, more solids dissolve into the water, thereby increasing coffee strength.

However, here’s the catch, as I already mentioned, bitter flavors are extracted at the end and if you brew your coffee for too long you will get overly bitter and it will not be drinkable. The key here is finding a perfect tradeoff.

Since Keurig doesn’t allow users to control the brewing time, so this topic isn’t worth discussing.

Here are some other ways you can make your Keurig coffee stronger.

Some other ways to brew a strong coffee in Keurig

1) User smaller brew sizes

K cups typically contain around 9-12 grams of coffee. And according to coffee experts, the best coffee-to-water ratio for a strong cup of coffee is 1:15 to 1:17.

Doing some math, 9-12 grams of coffee can only be sufficient for a 5-7 oz brew size.

With the Keurig, I only brew 6 oz cup size and that’s where I get my perfect and flavorful drink. Anything above that size, like 8, 10, or 12 oz is watered down.

You should only use 4 oz or 6 oz brew size if you really want stronger coffee, and if you are craving for more coffee, brew two K cups instead of one larger size.

2) Preheat your machine

Water extracts more flavors from coffee grounds at higher temperatures. According to the specialty coffee association, the best temperature for brewing coffee is 195 to 205 degrees.

Keurig claims to brew coffee at 192 degrees, but if the machine is cold, this temperature drops very quickly and the water extracts flavors from coffee grounds at a much lower temperature.

That’s why it’s recommended to run a pre-heating cycle before actually brewing the coffee. In this way, the internal system of the machine will be heated. Consequently, the water temperature will not drop when you brew the coffee, thus resulting in a better flavor extraction.

3) Select the right k cups

Choosing quality coffee grounds or K cups is the key to making a strong and flavorful cup of coffee.

Dark roast or Medium-dark roasted 100% Arabica beans or K cups is a perfect choice.

These are my recommended K cups for the Keurig machine.

What does over ice mean Keurig

It’s a setting in some high-end Keurig models for brewing coffee over ice.

With the brew over ice button, Keurig brews at a lower temperature, and a smaller, stronger coffee so it doesn’t get diluted when poured over ice.

Currently, this feature is only available in Keurig Elite, Keurig Slim, and the Supreme series.

Final Thoughts on Keurig Strong Button

Keurig coffee makers are not well known for making the perfect cup of coffee, but they are well known for their convenience.

With pod-based machines, you can make coffee quickly and easily, but it isn’t much flavorful and it’s also not fair to expect to have a perfect cup of coffee in less than two minutes. You do have to compromise a little on taste.

But I believe that the strong button on Keurig actually makes some difference and makes your coffee more flavorful and stronger than the normal K-cup brew.

It’s fine to show some patience and wait extra 30 seconds for your machine to brew coffee if you want a stronger drink.

FAQs

Which Keurig Settings Makes The Strongest Coffee?

For a strong cup of coffee: Use the smallest brew size (4 oz or 6 oz), select the highest temperature settings (if your machine has this option), and press the strong brew button.

Why Is My Keurig Not Making Strong Coffee?

Perhaps it is time to descale your Keurig machine if you notice the intensity and flavor of your coffee have declined.
Over time, limescale buildup and scaling inside the Keurig machine ruin the taste of coffee and also damages the machine. So, it’s always a best practice to descale your machine on time.

Does a strong button raise the caffeine levels in your drink?

No, the strong button on Keurig has nothing to do with the caffeine level of your coffee drink. The caffeine content mainly depends on the amount and type of coffee grounds (or coffee-to-water ratio) you are using.
Since the amount of grounds in the K cup remains the same whether you press the strong button or not, the caffeine level does not change.
