Keurig Grind Size

When using regular coffee in Keurig, like in other coffee makers, the size of your grind has an impact on the extraction process. Keurig recommends starting with a coarser grind that is similar to the grind size of a french press. Work your way towards a medium to medium-fine grind to find the right grind size for your brew.

A finer grind will clog the reusable filter and slow down or totally disrupt the brewing process. Very fine grounds will seep through the filter basket and end up in your coffee.

Important Tip

Avoid compacting the coffee grounds in the filter because it can slow down the brewing process.

Keurig Grounds to Water Ratio

The golden ratio for coffee grinds to water is 1-2 tablespoons of grounds per 6 oz of water. Using this ratio as a general guide, you can adjust the amounts of grounds to come up with a ratio that satisfies your needs.

Why You Should Use Coffee Grounds in Keurig

The benefits of using coffee grounds in Keurig include

  1. Using fresh coffee grounds in Keurig enhances the flavor of your coffee.
  2. You are able to improve the strength of your brew by adjusting the coffee ratio
  3. You can create your own blend of coffee with different coffee beans.
  4. It is cost-saving. A tub of coffee is more affordable than a single-serve pod and you get less product with the coffee pod. You also use the same batch of coffee in different coffee makers such as pour-over coffee makers unlike k-cups that only go with single-serve brewers
  5. Using coffee grounds in Keurig is more convenient, especially in areas where K-Cup pods are not available to you. Coffee beans are readily available in most supermarkets and convenience stores.
  6. Using coffee grounds in Keurig is more environmentally friendly. You eliminate the frequent disposal of single-use K pods.
