Choosing between a 200g, 500g or 1kg bag of coffee sounds simple, but the right size depends on how many cups you make, how much coffee you use per brew and how quickly you will finish the bag. Buy too little and you are ordering again almost immediately; buy too much and the last portion may sit around longer than you intended.
This practical coffee bag size guide will help you estimate how far each size goes, then match it to your household and brewing routine.
Quick answer: which coffee bag size should you buy?
- Choose 200g if you are trying a coffee for the first time, drink occasionally, or want a separate decaf option without committing to a larger bag.
- Choose 500g if one person drinks roughly one coffee a day, or if you want a useful middle ground between variety and fewer reorders.
- Choose 1kg if two people drink coffee daily, one person makes several coffees a day, or you regularly serve family, flatmates or colleagues.
Those are starting points, not rules. Your dose matters more than the number printed on the bag.
How many coffees are in 200g, 500g and 1kg?
The easiest way to estimate is to divide the bag weight by the amount of ground coffee used for each brew. Many home recipes sit somewhere around 15–20g per cup or serving, while an espresso setup may use a dose within that range for a double shot. Your basket, brewer and preferred strength may call for something different.
| Bag size | At 15g per brew | At 18g per brew | At 20g per brew |
|---|---|---|---|
| 200g | About 13 brews | About 11 brews | 10 brews |
| 500g | About 33 brews | About 27 brews | 25 brews |
| 1kg | About 66 brews | About 55 brews | 50 brews |
These figures are estimates. A little coffee can remain in the grinder, and recipes for plunger, filter and espresso do not all use the same dose. Measure your usual dose once, then use that number for a more accurate calculation.
When a 200g coffee bag makes sense
You are exploring a new coffee
A 200g bag lets you learn whether a roast suits your palate and equipment before buying more. It is especially useful if you like rotating between flavour profiles rather than drinking the same coffee every day.
You drink coffee only a few times a week
If you make three coffees a week at 18g each, 200g provides roughly three and a half weeks of brewing. That is a manageable amount for an occasional drinker and easier to fit into a small kitchen.
You keep regular and decaf coffee at home
Two smaller bags can be more practical than one large bag when the household switches between caffeinated and decaf. CaffTail’s Cat Nap Decaf is currently available in 200g and 500g, whole bean or ground, so you can size the decaf supply around how often it is used.
Why 500g is the everyday sweet spot
For many solo daily drinkers, 500g is the easiest size to plan. At an 18g dose, one coffee a day uses about 126g a week and roughly 504g over four weeks. In other words, a 500g bag is close to a four-week supply for that routine.
It also reduces ordering frequency without forcing you into a full kilogram. If you sometimes make a second coffee or share with a guest, you will simply finish the bag sooner.
Two current options with both 200g and 500g sizes are Fur-ever Roast, a full-bodied 100% Arabica blend designed to work particularly well with milk, and Purrk Up, CaffTail’s bold medium-dark choice with dark chocolate notes and a smoky finish. Both are available as whole bean or ground, so the size decision does not have to dictate your grind choice.
When 1kg is the practical choice
A kilogram becomes sensible when coffee is a shared daily habit. Two people using 18g each per day need about 252g a week, or just over 1kg across four weeks. A single person making two coffees daily lands in the same range.
It can also suit a home office, a busy household or regular weekend visitors. Before buying, check the arithmetic against your real routine: number of coffee drinkers × coffees per day × grams per brew. That is more reliable than assuming every household uses coffee at the same pace.
CaffTail’s in-stock 1 KG Coffee Lover Combo Deal contains two 500g bags: one Purrk Up and one Fur-ever Roast. That split gives you two distinct options rather than a single kilogram of one blend—useful when different moments call for a bold cup or a smoother coffee made for milk.
Work out your ideal bag size in three steps
- Measure your normal dose. Weigh the coffee you use for one espresso, filter brew or plunger serving.
- Count your weekly brews. Include other people in the household and allow for weekends or working from home.
- Multiply dose by brews. If you use 18g and make 10 coffees a week, your weekly requirement is about 180g. A 500g bag would last a little under three weeks.
If your consumption sits between two sizes, think about what you value most. A smaller bag makes it easier to change coffees more often; a larger size means fewer reorders and may suit a steady household favourite.
Whole bean or ground: does it change the size decision?
The calculation is the same, but your equipment and habits matter. Whole beans suit people with a grinder who want to grind immediately before brewing. Ground coffee removes that step and can be the practical option when convenience matters. Choose the format your setup can use consistently, then select a bag size you can finish at your normal pace.
How to look after a larger bag
Keep coffee sealed between uses and store it in a cool, dry place away from direct sunlight, heat and moisture. Avoid repeatedly leaving the bag open while you prepare a brew. If you buy a two-bag 1kg combo, open one bag first and leave the second sealed until you need it.
A clean, dry scoop and a consistent storage spot also make the routine easier. The goal is not complicated equipment; it is reducing unnecessary exposure each time you make coffee.
Frequently asked questions
How long does a 500g bag of coffee last?
At 18g per brew, it makes about 27 coffees. That is close to four weeks for one coffee a day, or around two weeks for two coffees a day.
How many cups are in a 1kg bag?
Approximately 50 cups at 20g each, 55 at 18g, or 66 at 15g. Use your actual recipe for the best estimate.
Is 200g enough to try a new coffee?
Yes. At an 18g dose, 200g gives about 11 brews—enough to adjust your grind or recipe and decide whether the coffee belongs in your regular rotation.
Choose the size that fits your routine
The best-value bag is the one that matches how you genuinely brew. Start with 200g when experimenting, choose 500g for a steady solo routine, and consider 1kg when coffee is shared or brewed several times a day.
