Why can not I get twelve cups of coffee was brewing 12 cups?

It & # 39; s the holidays and extended family staying with you. You can brew a full pot of the brand new 12-cup Cuisinart. Relatives jockey joe in the morning, but only the first five lines to get to fill. The pot is empty. Urgh! Did you & # 39; d have a household – that & # 39; why he bought a large brewery. What went wrong?

The "cup" of coffee is not Intermediate 8 ounces

Coffee cup sizes are not standardized. Number of ounces make up the "cup" varies by the manufacturer. The same company also have models differ.

For example, a Bodum French press 3 cups of the "cup" measures 4 oz. But if using the 8-cup Bodum French press of the "cup" comes in 4.25 oz. But wait! Bodum makes vacuum brewers and "cup" is one of about 5.7 oz. Confused yet?

The experts also agree when you try to name the most commonly used measuring cups. Votes split between four 5 oz., and 6 oz, oz..

One thing is certain: the "cup" of coffee does not fill the typical 12 oz. coffee mug can be found in most American homes.

ounces Cup Popular coffee Brands

  • Bunn: 5 oz
  • Bodum (French Press): 4 oz 4.25 oz
  • Bodum (Vacuum): 5.7 oz
  • Capresso 5 oz
  • Cona: 5.5 5.7 oz oz
  • Cuisinart: 5 oz
  • Krups: 5 oz
  • Proctor Silex: 4.5 oz
  • Technivorm: 4.2 oz
  • ZOJIRUSHI: 5.1 oz

to complicate things even further, coffee machine instructions often say how much ground coffee to give each 6 oz of water. You & # 39; you see this indicator on the back of a can of Maxwell House coffee and released by the authorities, such as the National Coffee Association of USA, Inc., is further evidence of the lack of standardization.

Metric Conversion

So what & # 39; and the folks at ZOJIRUSHI? They may sit down and decide to have a cup of coffee 5.1 oz (5.0721 to be exact)?

Coffee brewers designed and marketed outside the United States often start out in metric units. The brewery will have the capacity in liters and the corresponding number of cups is a nice round number milliliters.

When these brewers sold in the United States, the cups will be unchanged, but is converted to ounces per milliliter – and frequently end up as fractional ounce. What looks strange.

ZOJIRUSHI a Japanese housewares company. The 10-c fresh brew coffee thermal capacity of 1.5 liters. It comes in 150 ml cup. But when you convert a fresh beer in ounces, the 1.5 liter will have a total capacity of 50.721 ounces – or 5.721 ounce cup. Yet strange – but understandable.

Extra size

Another thing to consider is when he realized that the 12-cup brewers serving fewer than six people, the tendency of Americans supersize. We love our SUVs and Big gulp. The coffee is no exception, as the "Trenta" size Starbucks recently introduced. The Trenta is a whopping 31 oz, 11 oz over the entire Starbuck & # 39; s already-huge "Venti" size.

"Click" is a trend in today's society, and it distorts our expectations. Instinctively, we want a "cup" of coffee to fill with your favorite ceramic mug or insulated travel mug. And these everyday objects are large.

Household coffee makers do not stop these expectations. Cup volumes more in line with historically lower the dose, and is consistent with a global perspective. (Can not find a Trenta- size of anything in the traditional European cafe.)


Divide and Conquer

this number mugs you can fill a cup of brewed coffee is so different from the numbers advertised on the box is actually a common source of consumer dissatisfaction with coffee purchase.

But a little bit of division is all that is needed to manage expectations when it comes to coffee cup size.

When buying a coffee machine, we recommend leaving the advertised number of cups completely ignored.

Instead, pay attention to the maximum number of ounces to the aquifer. Then measure the capacity ounce coffee mug or cup is typically used. Divide the tank capacity of the mug. It shows how many times you can spend with your favorite mug – or how many portions fair to expect.


  1. The brewer & # 39; and the number of advertised word "cup" is a dose and not a unit of measurement
  2. size coffee for much less than what & # 39; ve come to expect from

When you have to feed a crowd or fill travel mugs long commute, keep these things in mind, and everyone gets to fill.
