Let's start with the standard calculation for the proportion of coffee to water:

- Add .36 ounces of ground coffee by 6 ounce glass.

In your case, we need to change this to:

- Add 0.54 ounces of ground coffee by 9-ounce cup

Now we can find out how many portions of 0.54 you can get from a 12-ounce bag of whole beans.

First of all, suppose there is zero waste. So its 12 ounces of whole beans will be bothered by 12 ounces of ground coffee.

Simple divides the 12 ounces by 0.54 ounces per cup ... and you get 22 cups.

And that means, if you have two cups per day, your 12-ounce bag of whole beans will last it 11 days.

If you have three cups a day, it will last approximately 7 days.

Keep in mind, tastes vary. You may like a stronger beer, which means you will add more coffee in proportion to water. And vice versa.

I hope this helps!

If you want to learn to make coffee, it is not complicated. But there are a number of factors that you should keep in mind.

First, let's see how to make a coffee with the most popular of all the cafeterias: the drip brewer.

Drip brewers are the most used coffee manufacturers and can be found in most homes. They make a decent cup of coffee, although it is possible that you want to stay away from the lowest price range. The problem with cheaper drip brewers is that they do not heat the water at the correct temperature, nor do they do a very consistent job to spray hot water on coffee beating.

In a respect, make gourmet coffee the same as making a fine dinner. Never achieve a quality result unless it begins with the quality Ingredie
