Benefits of K-Cup Pods

While you can use your own ground coffee in some Keurig models, the popularity of K-Cups stems from the convenience, variety and quality they offer:

Single Serve Freshness

K-Cup pods are sealed for freshness. Brewing one at a time eliminates waste and the need to store open boxes of coffee that lose flavor.

Huge Variety of Flavors

With over 75 brands and 400+ pod varieties available, you can sample different roasts, intensities, regions, and flavors every day.

Different Roast Levels

Find light, medium and dark roasts from leading coffee brands. Whether you like bright, smooth or bold coffee, there’s a pod to match.

Decaf and Flavored Options

The pod system lets you enjoy decaf, reduced acid, flavored, iced and limited edition coffee options that would be impractical to buy for brewing whole pots.

Tea, Cocoa and Specialty Beverages

K-Cups encompass far more than just coffee. You’ll also find tea, matcha, hot cocoa, chai, iced beverages, apple cider, soup broths and more available as pods.

Recyclable and Compostable

Look for recyclable K-Cups and biodegradable pods. You can also add reusable filters to fill with your own grounds.

Convenient Customization

The pod-based system allows you to easily tailor the type of coffee, flavor, and strength to create your perfect customized cup.

Coffee and Beverages

One of the best aspects of Keurig machines is the wide selection of beverages you can brew to suit any taste:


You’ll find regular and extra bold K-Cup coffee pods in all the most popular varieties: breakfast blends, Colombian, dark roasts, espresso, French roast, house blends, and much more.

Iced Coffee

Brew your favorite coffee pod over ice for refreshing iced coffee. Some machines like the K-Supreme include a strong brew setting specifically for iced coffee.

Cold Brew Coffee

Steep your own smooth cold brew concentrate using grounds in the Keurig carafe models. Store it in the fridge and pour over ice whenever you need a cold coffee fix.

Lattes and Cappuccinos

The K-Cafe and Rivo models can transform your black coffee into creamy lattes and foamy cappuccinos with steamed milk.

Espresso and Ristretto

Using an espresso roast pod and the smallest 4 oz brew size can mimic a shot of espresso. For a sweeter, bolder option, try a ristretto pod.

Hot Chocolate

Nothing hits the spot like a steaming mug of rich hot cocoa topped with marshmallows. Look for Swiss Miss and other hot chocolate K-Cup varieties.

Herbal and Wellness Teas

Not in the mood for caffeine? Choose from a wide array of relaxing herbal teas in K-Cup pods. You’ll find chamomile, peppermint, earl grey and more.

Use Ground Coffee

The K-Duo and K-Cafe models allow you to brew using your own ground coffee instead of pods in the reusable filters.

Cleaning and Maintenance

To keep your Keurig brewing properly, make sure to follow the recommended cleaning and maintenance steps:

Regularly Descale

Run a vinegar based descaling solution through your machine every 3-6 months to prevent mineral buildup that can affect taste and performance.

Clean Water Reservoir

Every few weeks, empty the water tank completely, wash with mild soap and rinse thoroughly as it can collect residue.

Rinse K-Cup Holder

The pod holder where the needles puncture can collect grounds. Rinse this piece with water after brewing is complete.

Wipe Exterior

Use a damp cloth to wipe down the exterior as needed. Check the drip tray and remove any remaining liquid.

Inspect for Leaks

Examine around the water tank, pod holder, and piercing needles for any drips or leaks indicating potential clogs.

Remove Mineral Deposits

In hard water areas, calcium deposits may build up in the water reservoir. Remove these using descaling solutions.

Disassemble Parts

Depending on your model, you may be able to disassemble parts like the frother, drip tray, and reservoir for deeper cleaning.

Troubleshooting Common Problems

Like any appliance, Keurig brewers may experience some issues, but most are quite easy to troubleshoot:

Coffee Not Hot Enough

If your coffee isn’t hot when brewed, descale your machine, preheat it, increase the temperature setting, and rinse the inner workings.


Check for leaks around the pod holder, reservoir, tubing and piercing needle. Clean any debris clogging puncture points.

Error Codes on Display

Consult your owner’s manual for the meaning behind any flickering lights or error codes displayed so you can resolve the issue.

Problems Inserting or Ejecting Pods

A dirty pod holder or malfunctioning puncture needles could prevent you from fully seating pods in the holder. Clean and inspect for obstructions.

Brew Interrupted Mid-Cycle

If brewing stops mid-cycle, check if the reservoir is empty and needs refilled or if there are blockages preventing water flow.

Milk Frother Not Working

If you experience problems with milk frothing, clean the frothing wand fully, inspect for clogs, and ensure you are using appropriate milk types.
