While your daily coffee habit may seem more like a need, rather than a want, there's no debating that the cost of purchasing a hot cup of freshly brewed joe from your local cafe each morning adds up significantly.
With the average latte in Australia costing around four dollars a pop, when purchased from a coffee shop, a consumer that drinks five cups a week is looking at a total bill of over $1000 a year on coffee alone.
So, it should come as little surprise that making your own coffee each morning can save a significant amount of money. To figure out just how much you're saving - you may be wondering how many servings are in a single bag of coffee. While this question is simple, the answer can be a bit trickier.
Below is a guide that will help give you an idea of just how long a kilo bag of coffee will last you - and how many coffees you can get out of it.
A standard single shot coffee
The amount of espresso you use in your coffee will directly affect the rate at which you go through the bag of beans. The standard amount of beans required to make a single shot of coffee is seven grams. So, basic maths determines that a one-kilo bag of roasted coffee beans should have 142 single-serve shots of espresso.
If you're drinking two cups of coffee a day, seven days a week, this means that a one-kilo bag should last approximately ten weeks. Of course, this doesn't take into account any spillage - and it is only applicable if exactly seven grams of coffee is used for each serve.
A double shot coffee
While some people might dodge the double espresso shot at an expensive cafe to avoid extra charges - when making a coffee at home it's usually hard to stop at a single shot. Plus, it's important to take into account that some types of coffee drinks, like a long black, require two shots of espresso.
If you enjoy a coffee with a double shot in it, the amount of time your kilo of coffee will last will be reduced significantly. Using the same above calculation, a double shot will have twice as many coffee beans used as a typical shot - meaning fourteen grams. Therefore, a person who drinks two coffees - with a double shot of espresso in them - per day will get about five weeks out of a one-kilo bag of coffee.
Making the most of your coffee beans
If you're an avid coffee drinker, you should already know that different beans have varying undertones and flavours. To enhance the flavour in a specific coffee bean, there may be more espresso required. The same sentiment goes for the type of coffee drink you're creating - some variations that use strong contrasting flavours, like a latte with almond milk, may require more coffee to be used so that the flavour is prominent.
In order to achieve the perfect amount of beans for your preferred flavour pay off, we recommend playing around with the amount of coffee you used until you find the perfect ratio. For example, try making a coffee with just five grams of espresso, trying one with seven grams and one with ten. Once you find the balance of flavour you like best - you can use that to figure out how many cups of coffee are in a single bag of beans.
Ground coffee beans vs full roasted coffee beans
Most coffee connoisseurs tend to stick to buying full coffee beans, and grinding them before they make each coffee. This method ensures a fresher taste and a more desirable coffee flavour and aroma. However, it's almost guaranteed that particles of coffee will be spilled and wasted when it's ground each time. So, you're likely to get fewer cups of coffee out of a bag of beans.
On the other hand, pre ground coffee will likely make more cups than roasted whole coffee beans, because you won't be dealing with spillage or residue in the grinder. That being said, pre ground coffee loses its flavour profile much quicker than full beans. This is due to the process of oxidation, which occurs when the released aromas from the ground beans react with the oxygen in the air. In fact, studies have shown that coffee can lose about 60% of its aroma just 15 minutes after its ground. So, with that in mind, it's often worth forgoing a few cups of coffee (due to spillage) in order to get the most flavoursome brew possible.
