What is Keurig Strong Button and How it Works

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, What does the strong button do on 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 more flavorful and 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 a strong button on Keurig really brew a strong cup of coffee?

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

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.

Does the strong button on Keurig make more caffeine?

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.

However, the prolonged brewing process can cause a little bit of increment in the caffeine content.

How does a longer brew time make 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 make stronger coffee with Keurig

1) User smaller brew sizes

The cup size you choose while brewing coffee with your Keurig actually affects the strength of your coffee drink

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 with Keurig, and if you are craving 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.

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

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 an extra 30 seconds for your machine to brew coffee if you want a stronger drink.
