Key takeaways

• A 1kg bag of coffee beans makes up to 66 cups – roughly double a 500g bag, at a lower cost per cup.
• Buying 1kg means fewer orders, fewer deliveries, and no more running out mid-week.
• Stored correctly, 1kg of coffee beans stays at its best for up to four weeks – long enough for most households of two or more to finish the bag comfortably.
• With Pact’s 1kg bags, you’ll get coffee beans sourced directly from the world’s best growers, roasted fresh to order, and available on a subscription that you can pause or cancel at any time.

There’s a particular kind of morning that coffee drinkers will recognise. You go to the cupboard, reach for the bag, and find it lighter than it should be. You shake it. You peer inside. There’s enough for one cup, maybe – if you grind it fine enough and hope for the best.

Running out of coffee is one of life’s minor but genuinely irritating inconveniences. At Pact, the 1kg bag of coffee beans exists to solve that problem.

It’s the straightforward, no-fuss choice for anyone who drinks coffee every day and would simply like to stop thinking about whether they have enough.

But is it actually cheaper? The short answer is, at Pact, yes – with 1kg coffee beans, you can brew outstanding speciality coffee for just 43p per cup. 

But is it the right choice for you? Here’s everything you need to know.

How many cups of coffee does 1kg coffee beans make?

A 1kg bag of coffee beans makes up to 66 cups, based on a standard 15g dose per cup.

That’s enough for most two-person households to brew comfortably for three to four weeks without a second thought. For a solo drinker who starts every morning with a double shot, it’s a month’s supply in a single bag.

As with any brewing method, the exact number will vary depending on how you make your coffee:

Espresso

At 15g to 18g per double shot, a 1kg bag gives you between 55 and 66 espressos. 

If you’re dialling in a new bag in the first few days (making small adjustments to your grinder to master the extraction) you may use a little more initially. Once you’ve found your setting, the 66-cup figure is a reliable guide.

Filter/pour-over

A 15g dose per cup (perfect for the V60) gives you the full 66 cups. Filter methods are particularly rewarding with a larger bag, because you have the freedom to experiment with different ratios and recipes over time without rationing your supply.

Cafetière

At 15g per person per brew, a 1kg bag comfortably fuels a household of two for three to four weeks. 

If you’re regularly brewing for guests or a family, the 1kg bag makes even more sense – you’ll go through it at a natural pace without any of it sitting around long enough to lose its character.

How much does buying 1kg coffee beans save?

At Pact, 250g bags work at around 56p per cup. With 500g bags, you’ll pay 45p per cup, and if you buy a kilo of coffee, you’ll pay 43p per cup. This is when you buy House Coffee, for example.

You’ll get more coffee for proportionally less money, because the packaging, handling, and delivery costs are spread across a larger volume.

The saving per cup might look modest in isolation. But run it across a year of daily brewing and it adds up meaningfully.

A household drinking two cups a day will make roughly 730 cups over the course of a year. Even a few pence saved per cup represents a real difference across that volume – all without compromising on what’s in the bag.

Then there’s the time saving. Ordering 1kg rather than 500g means half as many deliveries over the course of a year.

On a subscription, that efficiency compounds: fewer orders to place, fewer deliveries to track, and fewer occasions where you find yourself a cup short on a Tuesday morning.

For context, Pact’s speciality-grade coffee, sourced directly from the world’s best growers, scored at 84 points or above, roasted fresh to order, still works out at a fraction of what you’d pay at a high-street coffee shop.

How long does 1kg coffee beans stay fresh?

Freshness matters in coffee, and it’s worth understanding how a 1kg bag fits into that picture.

As a general rule, roasted coffee beans are at their best within four weeks of the roast date. After that, a natural process called oxidation, where oxygen interacts with the oils in the bean, begins to gradually flatten the flavour and dull the aroma.

For a 1kg bag, this means the question of freshness comes down to one thing: how quickly does your household drink coffee?

If you and a partner each drink two cups a day, that’s four cups a day, or roughly 28 cups a week. A 1kg bag – giving you 66 cups – will last just over two weeks at that rate. Well within the freshness window, with no compromise on quality.

If you’re a solo drinker having one cup a day, a 1kg bag will take you longer to work through. In that case, a 500g bag on a more frequent delivery schedule may serve you better. The right size is the one you’ll finish while it’s still at its best.

The good news is that with the right storage (more on that below) you can protect the quality of your beans throughout the life of the bag, and get the best possible cup right to the very last scoop.

Who should buy 1kg coffee beans?

The 1kg bag is the right choice if any of the following sounds familiar.

You drink coffee every day without exception.

If coffee is a non-negotiable part of your morning, not a weekend treat, not an occasional indulgence, but a daily ritual, then the 1kg bag is built for you. 

It removes the low-level administrative burden of monitoring your supply and placing orders before you run out.

There are two or more of you brewing at home.

Two people drinking one or two cups each per day will move through a 1kg bag at a comfortable pace, finishing it well within the four-week freshness window.

You find yourself ordering coffee more often than you’d like.

If you’re regularly placing top-up orders or finding your 250g or 500g bags running out faster than expected, a 1kg bag, particularly on a subscription, is the most straightforward fix.

You want to spend less time thinking about coffee logistics and more time enjoying the cup.

The 1kg bag on a Pact subscription means freshly roasted speciality coffee arrives at your door on a schedule that matches how you drink, in a quantity that means you’ll never be caught short.

How to keep 1kg coffee beans fresh for longer

A larger bag rewards good storage habits. Here’s how to protect your investment from the first cup to the last.

Seal it properly after every use.

The resealable Pact bag is designed to keep oxygen out. Squeeze the excess air from the bag before sealing the zip-lock each time – it takes five seconds and makes a genuine difference over the life of the bag.

Store it somewhere cool and dark.

A kitchen cupboard away from the hob and out of direct sunlight is ideal. Heat accelerates the breakdown of the oils in the bean. Sunlight does the same. Neither is your coffee’s friend.

Don’t store it in the fridge.

The temperature change every time you open and close the fridge door creates condensation, which can strip flavour from the beans and cause them to absorb other smells. A dry, room-temperature cupboard is better than a cold one.

Use an airtight canister for the long haul

For a 1kg drinker, a Pact Airtight Canister is a genuinely worthwhile addition. It features an inner lid that actively removes and seals out air, not just traps it – which extends the peak flavour window meaningfully. 

Decant your beans into the canister after opening and you’ll notice the difference right through to the final cup.

The case for subscribing to 1kg deliveries

Buying 1kg as a one-off is a good idea. Subscribing to 1kg deliveries is a better one.

A Pact subscription means your coffee is roasted fresh to order and dispatched to arrive at the right point in your freshness window – not sitting in a warehouse waiting for you to remember to reorder. You set the frequency that matches how you drink, and Pact takes care of the rest.

The subscription can be paused, skipped, or adjusted at any time. If you go on holiday, pause it. If you find you’re building a stockpile, extend the gap between deliveries. If you want to try a different coffee, switch it. 

This way, you’ll never run out and never end up with more coffee than you can drink while it’s at its best.

Is it cheaper to buy 1kg of coffee beans than 500g?

Yes. A 1kg bag offers a lower cost per cup than a 500g bag, because the packaging, handling, and delivery costs are spread across a larger volume. 

Over a year of daily brewing, the saving compounds meaningfully – particularly on a subscription with half as many deliveries.

How long does 1kg of coffee beans stay fresh?

Roasted coffee beans are at their best within four weeks of the roast date. For a household drinking four or more cups a day, a 1kg bag will be finished comfortably within that window. Stored correctly (sealed, cool, dark, and away from moisture) the beans will hold their quality throughout.

Who should buy 1kg of coffee beans?

The 1kg bag suits daily coffee drinkers, households of two or more, and anyone who wants to stop running out mid-week. 

It offers the best value per cup in the Pact range and, on a subscription, means you never need to think about reordering.

What is the best way to store 1kg of coffee beans?

Seal the bag after every use, store it somewhere cool and dark away from heat and sunlight, and avoid the fridge. 

For the best results across the full life of a 1kg bag, a Pact Airtight Canister – which actively removes air rather than simply trapping it – is well worth using.
