Technivorm Moccamaster CDT Grand Coffee Maker

Place the CDT Grand on a level, water-resistant surface. Fill the water reservoir by lifting the lid and pouring cold, filtered water up to the 1.8L / 60oz (15 cups) maximum fill line. Do not exceed the max fill line. Plug in and flip the on/off switch to start — there are no programmable settings or timers on the CDT Grand. The thermoblock heats water to 196–205°F and begins brewing in about 4–6 minutes.

Use a standard #4 flat-bottom basket paper filter. Fold the seam of the filter before inserting to help it seat flat in the basket. Add medium-ground coffee at approximately 6 grams per 5oz of water (or use the SCG-standard guideline of roughly 1 rounded tablespoon per 5–6oz). The Moccamaster is SCA Gold Cup certified — brewing within the recommended ratio and at correct temperature delivers ideal extraction.

The CDT Grand is Moccamaster's large-capacity model, designed for small offices, cafés, and home entertaining. Its flat-bottom brew basket requires flat-bottom #4 basket-style filters — NOT cone filters. Always brew the full 60oz capacity. Brewing partial volumes in the CDT Grand produces under-extracted coffee because the flat-bottom basket design is optimized for full-carafe water distribution.

Brewing with the CDT Grand

The CDT Grand uses a flat-bottom brew basket — use flat-bottom #4 or basket-style filters rather than cone filters. Always brew the full 60oz capacity for best results — the flat-bottom basket is designed for full-volume extraction. Brewing less than a full carafe in the CDT Grand produces under-extracted, weaker coffee.

Automatic Drip-Stop Basket

When you remove the carafe from the hotplate or carafe holder, the brew basket automatically stops the flow of coffee — preventing drips. This allows you to pour a cup mid-brew. Return the carafe and flow resumes automatically. The simplest Moccamaster operation: fill, switch on, and go.

Coffee Quality Tips

Use freshly roasted, freshly ground coffee for best results — the Moccamaster's precise temperature control is wasted on stale beans. A medium grind is optimal (similar to sea salt texture). Avoid over-filling the basket — too much coffee can slow flow and cause overflow. The Moccamaster's thermoblock maintains 196–205°F throughout the brew, which is within the SCA Gold Cup standard for optimal extraction.

After Each Use

Discard the used filter and grounds. Rinse the brew basket under warm water. Wipe the exterior and brewing area with a damp cloth. Rinse the carafe with warm water.

Thermal Carafe

Hand-wash the thermal carafe with warm soapy water. Rinse thoroughly. The carafe is dishwasher safe but hand-washing maintains the vacuum seal and prolongs the travel lid's sealing ability. For coffee staining inside the carafe, soak with a mixture of warm water and baking soda or use a carafe cleaning tablet.

The thermal carafe keeps coffee hot for approximately 1 hour without a heat source. The Brew-Thru Lid allows direct brewing into the closed carafe — always use the Brew-Thru Lid during brewing. Use the Travel Lid for transport to maintain temperature longer.

Monthly — Descaling

Descale every 2–3 months depending on water hardness. Use a Moccamaster-approved descaler or citric acid solution (1 tsp per cup of water). Fill the reservoir with the descaling solution and run a full brew cycle without coffee. Follow with 2–3 full cycles of clean water to flush completely.

Water Reservoir

Wipe the inside of the water reservoir periodically with a damp cloth. If mineral deposits form, use the descaling solution described above.

Coffee Tastes Weak

Ensure you are brewing the full 60oz capacity — the CDT Grand is designed for full-volume brewing. If you need a smaller batch, a different model may be better for you like the KBGV select.

Filter Overflowing

Use flat-bottom basket filters only — NOT cone filters. Cone filters collapse against the flat basket sides and impede drainage, causing overflow.

Slow Brewing

Try to descale the machine. Also ensure you're using the correct flat-bottom filters — wrong filter type slows drainage significantly.
