Batch brew is filter coffee made in volume. A machine pours hot water over a bed of ground coffee, the brew drains through a paper filter into a carafe, and the café serves it by the cup for the next hour or two. No espresso machine, no pressure, no milk steaming. Just coffee, water and a filter.
At home, the same thing is called a filter coffee machine, a drip machine or a "pour and forget". The café version is bigger and more consistent. The principle is identical, which is why batch brew is the easiest café coffee to copy in your own kitchen.
The short version
- Batch brew is filter coffee brewed in a machine, usually a litre or more at a time.
- Cafés use it because it is fast, consistent and frees the espresso machine for milk drinks.
- Start at 60g of coffee per litre of water with a filter grind and water just off the boil.
- Serve it within an hour. Turn the hotplate off.
Why do cafés use batch brew?
Three reasons, and none of them are romantic.
Speed. A double shot of espresso takes a barista half a minute of attention. A cup of batch brew takes four seconds and a pour. When the queue is out the door at 7.15am, that matters.
Consistency. A good batch brewer holds temperature, doses water evenly and does not have opinions. Every cup from one batch tastes the same as the last, which is more than can be said for the fourth flat white in a rush.
It shows off the coffee. Espresso concentrates everything. Batch brew stretches the same coffee out into a longer, lighter cup where the individual flavours have room. A washed Colombian tastes like green apple and milk chocolate in a filter cup in a way it never quite does under nine bars of pressure. That is why so many specialty cafés put their single origins on batch.
There is a fourth reason cafés do not put on the sign. Batch brew is cheaper to make per cup than espresso, so they can sell a bigger drink for less money and still come out ahead. That is not a criticism. It is a good deal for everyone.
Is batch brew the same as filter coffee?
Yes, near enough. "Filter coffee" describes the method: water passes through coffee and a filter by gravity. "Batch brew" describes the scale: a lot of it, made at once, by a machine. A pour over is filter coffee made one cup at a time by hand. Batch brew is filter coffee made by the litre without the hand.
The home version is the filter machine that has been sitting on the bench at your parents' place since 1994. The difference between that and a café batch brewer is mostly temperature control and how evenly the water hits the coffee. Modern home filter machines have closed most of that gap, and even an old one will make a decent cup if you get the ratio and grind right.
How do you make batch brew at home?
You need a filter coffee machine, paper filters, ground coffee and water. Scales help. A grinder helps more. Here is the starting recipe we recommend.
The ratio
60g of coffee per litre of water. That is our starting point, not a law. It works out to:
| Water | Coffee |
|---|---|
| 500ml | 30g |
| 750ml | 45g |
| 1 litre | 60g |
| 1.25 litres | 75g |
If you do not have scales, a level tablespoon of ground coffee is roughly 5–6g, so a litre needs about 10–12 tablespoons. That is more than most people put in. Under-dosing is the single most common reason home filter coffee tastes thin and slightly sour.
The grind
Batch brew wants a medium grind, a little coarser than table salt. Too fine and the water backs up, drains slowly and pulls out bitterness. Too coarse and it rushes through weak and sharp.
If you grind at home, start in the middle of your grinder's range and adjust one step at a time. If you do not, FARCOFF coffee is available ground for filter machines. Choose the Filter grind on any bag.
The water
Water just off the boil is right for a filter machine, and most machines handle that for you. If your machine runs cool, it will show up as a flat, slightly sour cup no matter how you grind. If you are boiling a kettle for a manual filter brewer, give it about 30 seconds off the boil first.
Use water you would happily drink. Heavily chlorinated tap water tastes like heavily chlorinated coffee.
The steps
- Put a paper filter in the basket. If the filter is thin, rinse it with hot water first to take away any paper taste.
- Weigh the coffee into the filter and give the basket a gentle shake so the bed is level.
- Fill the reservoir with the matching amount of water.
- Start the machine. It should take about four to six minutes to brew a litre.
- When it stops dripping, take the carafe off the hotplate, swirl it once to mix the top and bottom of the brew, and pour.
That is the whole method. The reason people get it wrong is not complexity. It is skipping the scales.
What are the common batch brew mistakes?
Leaving it on the hotplate. This is the big one. A glass carafe sitting on a heating element for 40 minutes cooks the coffee. It goes flat, then bitter, then genuinely unpleasant. Drink it within the hour or pour it into a thermos. A thermal carafe machine sidesteps the problem completely.
Too little coffee. Covered above, but it deserves a second mention. If your cup tastes weak and a bit sour, add coffee before you touch anything else.
Stale, pre-ground coffee from the supermarket. Ground coffee loses aroma quickly. A bag that was ground months ago and has been open for three weeks is not going to taste like the café's batch brew, no matter how good the machine. Buy less, buy more often, and look for a roasted-on date. Every FARCOFF bag carries one, plus a batch number.
Never cleaning the machine. Old coffee oils build up in the basket, the carafe and the spray head. They taste rancid. Rinse the basket after every brew, wash the carafe properly, and run a descaling cycle every month or so if your water is hard.
Fiddling with everything at once. If the coffee tastes off, change one thing: grind, dose or water. Brew again. Then change the next thing. Two changes at once tell you nothing.
Which coffee is best for batch brew?
A medium roast with clear flavours tends to shine in a filter cup, because the method dilutes rather than concentrates. All of our coffees suit espresso, pour over and filter equally well, so batch brew is not going to punish any of them. A few starting points from the range:
- Smooth Coffee at /products/blend-2-smooth-coffee is our obvious pick. Caramel, milk chocolate and a little cardamom, medium roast, and our brew guidance for it is filter or espresso. It is the coffee for the household where everyone takes theirs differently.
- Colombia at /products/single-origin-colombia gives you the café single-origin experience: green apple, milk chocolate and hazelnut in a clean, balanced cup.
- Ethiopia at /products/single-origin-ethiopia is the one for people who like their filter coffee fruity. Apricot, yellow peach and bright citrus acidity.
Pick the Filter grind if you do not have a grinder, and the 1kg bag if the house gets through a litre a day. Our coffee is freshly roasted in St Peters, Sydney, and reaches its peak flavour up to four weeks after roasting, so a kilo bought for a batch brew habit will be drunk while it is at its best.
Try it with FARCOFF
If you want to find out which of the three blends suits your filter machine before committing to a kilo, FARCOFF 3 Ways is three 250g bags — Traditional Espresso, Smooth Coffee and Sweet & Complex — in whichever grind you choose. Pick Filter, brew a litre of each over a week, and keep the one the household argues about least. Coffee for people with things to do, made a litre at a time.
Freshly roasted. Roast date on every bag.
