The Complete Guide to Using Technivorm Grand Coffee Filters Flat Bottom

Introduction

Have you ever wondered how to achieve the perfect cup of coffee using the Technivorm Grand Coffee Filters with a flat bottom? You’re in the right place. This complete guide will provide you with all the information you need to make the most out of your Technivorm Grand Coffee Filters flat bottom, ensuring that every cup of coffee you brew is of the highest quality.

Understanding Technivorm Grand Coffee Filters

Technivorm, the Dutch company behind Moccamaster, makes these 110 mm flat bottom filters for its two batch brewers, the CD Grand and the CDT Grand. Most other Moccamaster models take No. 4 cone filters instead. These flat bottom filters are designed to maximize the contact between coffee grounds and water, thus enhancing the extraction process.

What Are Flat Bottom Filters?

Flat bottom filters, as the name suggests, have a flat bottom that allows coffee to spread evenly across the surface. This design differs from the traditional conical filters, which funnel coffee into a single point.

Benefits of Flat Bottom Filters

Flat bottom filters offer consistent extraction, a quicker brewing time, and can accommodate more coffee grounds. These characteristics make them suitable for brewing larger quantities of coffee without sacrificing flavor or quality.

Preparing to Brew

Before you start brewing, it’s essential to gather the necessary equipment and understand the setup process for your Technivorm coffee maker.

Equipment Needed

Freshly ground coffee beans
Water
Scale (optional, for precise measurement)

Setting Up Your Coffee Maker

Make sure your Moccamaster CD Grand or CDT Grand is clean and the brew basket is seated. Place the 110 mm flat bottom filter in the basket. Make sure the filter is securely fitted to avoid any mishaps during the brewing process.

Selecting Your Coffee Beans

The type of coffee beans you choose plays a key role in the taste and quality of your brewed coffee.

Coffee Bean Types

There are two main types of coffee beans: Arabica and Robusta. Arabica beans are known for their smooth, complex flavors with a range of acidity, while Robusta beans tend to have a stronger, more bitter taste with higher caffeine content.

Freshness and Quality

For the best results, use freshly roasted coffee beans. Ground coffee loses its delicious aroma and taste over time, so grind your beans just before brewing to ensure maximum freshness.

Grind Size for Flat Bottom Filters

The grind size affects how quickly water passes through coffee grounds. For flat bottom filters, a medium grind size is ideal. Too fine, and the coffee might over-extract, resulting in a bitter taste. Too coarse, and you may have under-extracted coffee, leading to a weak and sour flavor.

Measuring the Coffee and Water

The coffee-to-water ratio is vital in brewing the perfect cup of coffee. An incorrect ratio can spoil an otherwise great brew.

Standard Coffee-to-Water Ratio

A general guideline is to use one to two tablespoons of coffee per six ounces of water. But, the exact ratio can be adjusted based on personal preferences.

Using a Scale for Precision

For more consistency, you can use a scale to measure your coffee grounds and water by weight. This method ensures that you get the precise ratio every time, enhancing the overall flavor and quality of your brew.

Suggested Ratios

Coffee (grams)	Water (grams)	Strength
14	240	Mild
18	240	Medium
22	240	Strong

Brewing Process

Now that you have everything prepared, let’s move on to the actual brewing process.

Heating the Water

Start by heating your water to around 200°F (93°C). Water that is too hot or too cold can negatively affect the extraction process. The CDT Grand heats water to 196°F to 205°F on its own, so there is nothing to set.

Pre-Wetting the Filter

Pre-wetting the flat bottom filter helps to eliminate any paper taste. Pour some hot water over the filter, letting it run through to warm up the carafe. Discard the water before adding your coffee grounds.

Adding Coffee Grounds

Evenly spread your freshly ground coffee into the pre-wetted filter. Level the grounds to ensure even extraction.

Brewing Time

Press the button or lever to start the brewing process. The Technivorm coffee maker will take care of the rest, ensuring that water runs through the coffee grounds at the perfect rate.

Maximizing Flavor

To maximize the flavor and enjoyment of your coffee, there are a few additional steps you can take.

Stirring During Bloom Phase

During the initial stage of brewing, known as the bloom phase, coffee grounds release gases. Stirring the coffee grounds during this phase can help ensure even saturation and extraction.

Controlling the Pour

If you’re using a manual pour-over method with your flat bottom filter, controlling the pour rate and pattern can improve the extraction process. Start by pouring water slowly and evenly, covering all the grounds.

Keeping Equipment Clean

Regular cleaning of your Technivorm coffee maker and filters ensures no residues affect the taste and quality of your coffee. Make a habit of thoroughly cleaning all components after each use.

Common Mistakes and How to Avoid Them

Even with the best equipment and ingredients, mistakes can happen. Here are some common brewing errors and how to avoid them.

Using Incorrect Grind Size

Using the wrong grind size can drastically impact the flavor of your coffee. Stick to a medium grind for flat bottom filters to ensure balanced extraction.

Over or Under-Extraction

Over-extracted coffee tastes bitter, while under-extracted coffee can be sour. Using the proper coffee-to-water ratio and correct brewing time helps strike the right balance.

Inconsistent Measurements

If you don’t measure your coffee and water consistently, you may get varying results each time you brew. Use a scale for precise measurements to maintain consistency.

Troubleshooting Tips

If your coffee doesn’t taste quite right, don’t worry. Here are some troubleshooting tips.

Bitter Coffee

Use a coarser grind.
Reduce brewing time.
Ensure water temperature is around 200°F (93°C).

Weak Coffee

Use a finer grind.
Increase the amount of coffee grounds.
Ensure even distribution of water over the grounds.

Sour Coffee

Use fresher coffee beans.
Increase the brewing temperature.
Adjust the coffee-to-water ratio for a balanced extraction.

Advanced Tips for Enthusiasts

For those who want to take their coffee brewing to the next level, here are some advanced tips.

Customizing Your Coffee

Experiment with different coffee bean types and origins to find your favorite flavor profile. Each region offers unique taste notes, from fruity and floral to nutty and chocolatey.

Water Quality

Water quality can significantly impact your coffee taste. Use filtered water to remove impurities that might affect flavor. Some coffee enthusiasts even use specific mineral blends in their water for optimal results.

Experimenting with Brew Time

Small adjustments in brew time can yield different flavors. Try brewing slightly longer or shorter to find your preferred taste.

Temperature Control

Although Technivorm coffee makers control temperature well, some advanced users might explore pre-heating vessels or using thermal carafes to maintain optimal temperature throughout the process.

Which Moccamaster Brewers Use Grand Flat Bottom Filters?

Only two do. Moccamaster support lists the CD Grand and the CDT Grand as the models that take 110 mm flat bottom paper filters. Most other Moccamasters, including the home brewers most people own, take No. 4 cone filters, and the Cup-One takes No. 1 cones. Buy the wrong box and the paper will fold, collapse, or overflow.

Spec	Moccamaster 110mm Grand Coffee Filters
Item number	85025
Shape and size	Flat bottom, 110 mm
Count	100 per box
Paper	Oxygen whitened, no chlorine bleach, no glue
Fits	CD Grand and CDT Grand
Price, September 2026	$12.95 at Moccamaster USA

That works out to about 13 cents a batch. For a brewer that makes 15 cups at a time, the paper is the cheapest part of the pot.

Full Batch Recipe for the CDT Grand

The CDT Grand holds 1.8 liters (60 oz), brews at 196°F to 205°F, and finishes in 6 to 7 minutes. Moccamaster recommends brewing the full amount every time, so build your recipe around a full tank. At a 1:17 ratio, that is about 105 grams of coffee. Go up to about 115 grams if your office likes it stronger.

Open the filter and press it into the basket so the pleated walls sit flat against the sides.
Rinse the paper with hot water from a kettle and pour the rinse water away.
Add 105 to 115 grams of medium ground coffee, then give the basket a gentle shake to level the bed.
Fill the reservoir to the 1.8 liter line with cold filtered water.
Check that the basket’s drip stop is open, set the thermal carafe in place, and switch on.
When the drip stops, swirl the carafe before the first pour. The coffee that drips first is stronger than the coffee that drips last.

Our coffee ratio guide explains how to move between 1:15 and 1:17 if the pot tastes thin or heavy.

Troubleshooting a Grand Brew Basket

The basket overflows: the grind is too fine, the dose is too big, or the drip stop is closed. Start coarser and check the stop.
Grounds in the carafe: one wall of the filter folded inward during the brew. Wet the paper before adding coffee so it clings to the basket.
Coffee tastes flat after a few months: the heater may be scaling up. Our descaling guide covers how often to clean and what to use.
