  • offers an industry leading 5-year Limited Warranty
Moccamaster Brewers:
  • meet strict brewing guidelines set forth by the ECBC (European Coffee Brewing Centre), SCA (Specialty Coffee Association), these guidelines include:
    • Brew at the correct temperature (196°F – 205°F)
      • with a copper boiling element
      • which is important for coffee soluble extraction
    • Steep coffee grounds for the right amount of time (less than 6 minutes to brew full cycle)
      • via a cone-shaped brew-basket (for < 1.8 liter brewers)
    • Hold brewed coffee at the correct temp, without burning (175°F – 185°F)
      • using a unique, independent hot-plate element, auto-shut-off after 100 minutes or via a thermal carafe
  • are made with durable metal housing, and where plastics are used, they are BPA/BPS/BPF and Phthalate FREE
  • use a copper boiling element which allows for consistent water temperature control (copper is antibacterial in function)
  • are simple to use, with a quiet brew process
  • are energy efficient, timeless in design, long-lasting, reliable, cleanable, recyclable and sustainable!
What are the differences between Moccamaster brewer models?
  • Volume:  10-oz (Cup-one), 1-liter (32oz/8-cup), 1.25-liter (40oz/10-cup), 1.8-liter (60/15-cup)
  • Body:  K Series: rectangular tower housing, C Series: cylindrical/round tower housing
  • Carafe: Thermal Carafe (without hot-plate) or Glass Carafe (with hot-plate)
  • Brew-Basket: Manual-adjust drip-stop, Automatic drip-stop, No drip-stop
  • Auto-off power switch: Glass carafe models switch off at 100 minutes, Cup-One models immediately switch off after brewing. There isn’t a need for an AO power switch on Thermal Carafe models because the copper boiling element automatically turns off via the float switch, after water drains from the water reservoir. The power switch light remains on, but only indicates it’s ready, and doesn’t draw any power to the element.
Do all models produce the same quality coffee?

Yes! Moccamaster brewers include different colors, styles and volumes, but all produce to a Gold Cup Standard (ECBC/SCA).

Where is Moccamaster sold?

Moccamaster products can be found at many gourmet houseware and upscale boutique retailers throughout the USA and Canada, as well as specialty cooking stores, coffee roasters or Moccamasters are available around the globe, especially in the Nordic region where coffee consumption is the greatest (per capita) in the world. They demand quality in the cup, they buy Moccamaster!

Brewing Coffee

What's important when searching for that complex, clean, crisp, fully infused, flavorful cup of coffee?

Coffee bean quality, grind, fresh water quality and formula are all factors in brewing the gold cup, but ultimately, it’s the brewing process that plays the all-important final role!

Does Coffee Grind (particulate) size make a difference?

Brewing parameters are important, however grind is also important. Consistent and equal grind particulate size will ensure your coffee-to-water contact time is producing an even homogeneous extraction and a well balanced gold cup. Moccamaster recommends a medium (drip) grind particulate size, following the water-coffee ratio below. Too fine a grind may cause an over-flow of the brew-basket and/or an over-extracted bitter tasting outcome and too course a grind may under-extract and cause a flavorless result.

What about water?

If it tastes good to drink, it’ll make good coffee. If you wouldn’t drink it, then don’t brew with it! We recommend fresh tap water if it tastes good, otherwise filtered or bottled water is fine too. We do not recommend the use of reverse osmosis filtered water or distilled water.

What formula does Moccamaster recommend?

Volume(note: European cup size is 4oz) Grams Moccamaster 2-Tbsp Scoop Table spoons "About"
1.8 L / 15-Cup (Grand) 99 10 20 10-level scoops
1.25 L / 10-Cup 68.75 6.66 13.32 7-level scoops
1 L / 8-Cup 55 5.33 10.66 5-heaping scoops
3/4 L / 6-Cup 41.25 4 8 4-level scoops
5/8 L / 1/2 pot (5-Cup) 34.4 3.33 6.66 3-heaping scoops
1/2 L / 4-Cup 27.5 2.66 5.32 3-level scoops
0.3 L / Cup-one 16.5 1.66 3.32 2-level scoops

NOTE: If the final brewed coffee seems too strong, we recommend not changing the formula, but adding hot water to your cup, weakening the coffee, while protecting the taste. If you find the final brewed coffee too weak for your taste, we recommend changing your coffee variety and/or roast profile; we do not recommend increasing the formula.

What is Coffee Bloom?

Moccamaster brewers are scientifically designed to brew with an ultra-precise, pre-immersion drip-style system, which creates a natural pulse action process. As water, heated to the proper temperature, contacts the coffee grounds, a gas is released, causing the “coffee bloom”, which is the flavor being released from the coffee grounds. The pulse action can easily be viewed through the clear water reservoir and glass transfer tube. While the coffee bloom can be witnessed when peaking under the brew-basket lid near the beginning of the brew process, we don’t recommend removing the brew-basket lid as it will release heat, and could potential cause a burn, compromising your safety.

What size filter does my brewer take?
  • All of our 8- and 10-cup coffee brewers use No. 4 conical filters. This includes the following models: KBGV Select, KBG, KBGT, CDGT, KB, KBT, and KBTS.
  • Our Cup-One coffee brewer uses No. 1 conical filters.
  • Our CD Grand and CDT Grand coffee brewers use 110mm flat-bottomed filters.

All three filter sizes are available to purchase on our website.

Is there a difference in filters and why does Moccamaster recommend oxygen whitened paper filters?

Moccamaster oxygen whitened filters are the perfect choice for clean, crisp, unflavored coffee. Brown unbleached filters may leave a “cardboard” taste in your coffee, and permanent wire-mesh type filters can clog with coffee oils quickly, overflowing the brew-basket and/or steeping the coffee too long, potentially resulting in over extracted bitter tasting coffee.

Brewer Questions

Can the Moccamaster instruction manual be found online?

Yes, Technivorm Moccamaster USA website:

What are the settings on the manual-adjust drip-stop brew-basket for?

The settings are: Open, Partial Open, and Closed.

  • Open is for normal brewing of 5 or more cups
  • Partial Open slows down the coffee/water saturation time (drain process), which allows the coffee to steep a bit longer for partial carafe coffee brewing of less than 5 cups.
  • Closed is meant for emptying the basket at the end of the brew cycle and NOT for pause and pour. Since the entire cycle only takes less than 6 minutes, we recommend waiting until the full cycle is complete to assure Golden Cup quality perfection in every cup.
Why is there a dual-phase hot-plate switch on Glass Carafe models? Is it illuminated or not?

This switch setting is adjustable when brewing a ½ carafe (16-20oz mug) or full carafe of coffee, allowing you to control holding temp within the range of 175°F – 185°F. We recommend setting at Low for ½ carafe brewing or for drinking “black” coffee and High for a full carafe or for “cream” coffee drinkers. (Note: Model K-741-AO (Homeline) does not have a dual-phase hot-plate switch, and holds about 180°F on the same hot-plate element and will not burn your coffee!)

The hot-plate switch is NOT illuminated on current models, however on older models it was. The on/off power switch is still illuminated.

Is the foot-plate optional for the thermal carafe brewers?

For the automatic, drip-stop brew-basket (KBGT/CDGT) models, the foot-plate is not optional and must be used. The minimal extra height of the carafe is necessary to assure sufficient contact with the brew-basket drip-stop lever. If not used this can cause a very slow drain of the brew-basket and potentially overflow the brew-basket or even slowly drizzle down the side of the bracket causing the tower to appear to be leaking. For the manual-adjust, drip-stop brew-basket models the foot-plate is not necessary. This includes: KBT, KBTS, CDT, CDT Grand.

Why do Thermal Carafe models come with two lids?

Moccamaster Thermal Carafe model brewers come with 2 different lids.

  1. The Brew-Thru-Lid is engineered to allow coffee to drip into the carafe during the brew cycle and minimize heat loss while holding the coffee. The brew-thru-lid is also a pour-thru lid, so there isn’t a need to take it off or loosen it to pour coffee. For this reason, if properly used, your coffee will stay hot for up to 1 hour (although coffee experts suggest consumption within 30 minutes).
  2. The Travel Lid is for keeping coffee hot for longer than an hour or for traveling with your carafe. The travel lid is also a pour-thru style, but you’ll need to loosen it by ¼ to ½ a turn to expose the pour spout within the lid. After pouring, retighten to keep the coffee warm and to make it spill proof.
Why doesn’t the Grand brewer have graduated liter/cup markings on the cool water reservoir?

The Grand models were designed for café’s, small offices or the entertaining home, and designed to produce 1.8 liters of coffee per brew cycle. The flat-bottom, commercial type, brew-basket (110mm filter), needs sufficient coffee bed depth and water ratio to assure essential saturation and extraction to meet Golden Cup standards. For this reason, a full carafe should be produced when using the flat-bottom brew-basket.

If the Grand brewer brew-basket is not flexible in brewing volume, can I make a smaller quantity by using a different brew-basket?

Technically Yes; the CD Grand (glass carafe) model is easily altered by substituting the brew-basket [use the 1.25L manual-adjust drip-stop brew-basket (round base) and use the correct water/formula ratio (previously noted)]. You’ll need to source the following parts from Technivorm Moccamaster USA to accomplish this flexible option: Brew-basket: #13192, brew-basket lid: #13114, 9-hole outlet-arm: # 53054 and #4 filters: 85022

You could accomplish the same satisfactory results with the CDT Grand Thermal Carafe brewer if you pre-heat the cool stainless steel thermal carafe. When brewing partial quantities into a stainless steel thermal carafe you must pre-heat the carafe so as not to lose coffee heat while warming the carafe.

Are there programmable timer features?

Moccamaster does not recommend programmable timers for brewing at a later time. Leaving water in the reservoir or coffee in the brew-basket overnight causes the water to go flat and the coffee stale by morning. Good coffee starts with fresh water and fresh coffee.

It’s the first thing you look forward to in the morning, why not make it the best it can be? After all, it only takes 6-minutes to brew a full carafe of coffee.


Why is there water remaining in my brewer once the brew cycle is complete?

Moccamaster doesn’t use pumps to push the water through, It’s the natural boiling process for this type of brewing system that creates the flow of water up and through to the brew-basket. Therefore, it is normal to have a few ounces of water remain in the boiling element. This is fine if you brew every few days, but if you brew every couple week, take extended vacation or are in a freezing environment, we recommend emptying the remaining small amount of water by removing the parts and turning your brewer upside down over the sink.

Why descale and clean? What is the recommended timetable?

Moccamaster brewers should last a lifetime, when cleaned and descaled properly! As with all coffee brewers, your Moccamaster should be descaled (removal of calcium/lime deposits-buildup) and cleaned (removing water residue/coffee oils) in order to maintain proper performance and great tasting coffee.

For descaling and cleaning your brewer we recommend Urnex brands:

  • Full Circle Descaler, Full Circle Cleaner
  • Urnex Dezcal Descaler, Urnex Cleancaf Cleaner

Other brands may harm the copper boiling element, potentially resulting in an unpleasant metallic after-taste. We don’t recommend vinegar, because it rarely descales sufficiently and may leave an after-taste.

Moccamaster recommends you clean and descale your brewer every 100 brew cycles. This can be easily remembered when you buy a box of 100ct filters.

Why are there so many parts?

Removable parts are essential for long-term maintenance and replacement.

Do you sell Accessories and Replacement Parts separately?

Yes, available at or at many fine retail partners. See store finder link for a store near you.
