Perfect Guide for CAPMESSO Stainless Steel Reusable K-Cups for Keurig 1.0

If you’ve switched from disposable K-cups to a reusable K-cup—great choice! Not only are reusable pods better for the environment, but products like the CAPMESSO Stainless Steel Reusable K-Cup also give you more control over taste, strength, and freshness.

But to get the perfect cup, you need to fill your reusable pod the right way. Too much coffee leads to overflow and messy brews, while too little means weak or watery coffee.

This guide walks you through **how to properly fill your reusable K-cup,how much coffee to use, and what mistakes to avoid—so you get a perfect brew every single time.

⭐ Why Proper Filling Matters

Your reusable K-cup is designed to allow hot water to flow through the grounds evenly. But if the pod is:

Overfilled: the lid won’t close properly and water can’t flow → causing overflow Underfilled: water passes too quickly → resulting in weak coffee Incorrect grind size:** can affect flow and extraction

Filling it correctly ensures strong, smooth, and consistent coffee.

⭐ What You Need

Step-by-Step: How to Properly Fill a Reusable K-Cup

Use the Right Coffee Grind (This Is Important!)

According to coffee experts at Home Grounds, medium grind creates ideal flow for single-serve brewers.

Keurig’s official support page also recommends avoiding fine grinds to maintain proper water flow.（https://support.keurig.com/）

For Keurig machines, the best grind size is:

✔Medium grind (similar to drip coffee)

Too fine (espresso grind) → clogs & overflow Too coarse → weak coffee with little flavor

If you grind your own beans, choose medium or medium-coarse for optimal flow.

Add the Recommended Amount of Coffee

For CAPMESSO reusable K-cups, the ideal fill amount is:

✔ (8–10 grams)

This level gives a balanced extraction and prevents overflow.

❌ Do NOT fill to the very top

Leave a little space so the lid can close properly and the water can circulate.

Gently Even Out the Coffee (Don’t Tamp!)

Use your spoon to lightly level the grounds.

⭐Why you shouldn’t press it down:

Tamping compresses the coffee → slows water flow → causes overflow or weak drip.

Just smooth the top—no pressure needed.

1、Close the Lid Securely

Before inserting into your Keurig, ensure the lid is:

  • ✔ Fully closed
  • ✔ Aligned with the pod
  • ✔ Snapped tight

A loose lid is the #1 cause of messy brews and splashing.

2、Choose the Right Brew Size

For strongest flavor with reusable K-cups:

☕ Recommended brew sizes:

  • 6 oz (strongest)
  • 8 oz (balanced)

Avoid 10–12 oz unless you prefer lighter coffee or add more grounds.

Common Mistakes That Lead to Overflow or Weak Coffee

  • ❌ Overfilling the pod

    Too much coffee blocks water flow.

  • ❌ Using fine espresso grind

    This clogs the filter and causes overflow.

  • ❌ Tamping the grounds

    Creates pressure your Keurig isn’t built for.

  • ❌ Using low-quality filters or plastic pods

This is why the CAPMESSO stainless steel design is superior—better flow, durability, and flavor.
