Quick Tips To Getting The Strongest Coffee From K-Cups

Now that you have selected the Strongest K Cup Coffee. How to brew it correctly to get the most out of it.

Adjust Temperature To Highest On Your Keurig

The temperature controls on your coffee maker are there for a reason; it is to keep your coffee at the right temperature to brew it at the right strength.

Many people put their K cups on at too low of a temperature which will prevent you from getting the most out of your K cup. So be sure to adjust the settings to the highest one possible.

Adjust Water Level To Full

Water doesn’t have much of an impact in brewing coffee, but it does make a difference. For the most even coffee strength, you will want to have the maximum amount of water in your K cup.

A good way to do this is to measure the water for an 8oz cup and then fill it up the rest of the way with additional water.

Preheat The Keurig

You may already do this, but preheating your coffee maker will help ensure that the temperature is hot enough for your K cup.

This will help you get the most out of your K Cup and also prevent your drink from getting too cold, which will ruin it.
