Forget café queues and filter faff - cold brew just got stupidly easy.
Our FAFF Mega Coffee Bags are packed with 50g of speciality coffee. Drop one in a litre of water, chuck it in the fridge overnight, and wake up to a week’s worth of smooth, bold, low-acid cold brew. No gadgets. No filtering. Just effortless iced coffee, on tap.
Why cold brew?
Because you don’t want bitterness in your glass—or your day. Cold brewing uses time, not heat, to extract flavour. The result? Coffee that’s smoother, sweeter, and easier on your stomach. It’s also ridiculously versatile—drink it straight, mix with milk, make coffee cocktails, or pour it over ice cream. You do you.
Cold Brew with a FAFF Mega Coffee Bag
You’ll need:
-
1 litre jug or jar with a lid
-
A fridge
-
Ice, milk, or whatever you're mixing it with
How to:
1. Steep
Place the Mega Bag in your jug and pour over 1 litre of cold water. Give it a little nudge so it’s fully soaked.
2. Chill
Seal it and pop it in the fridge for 12–18 hours. That’s your extraction window. Taste test around the 12-hour mark—go longer if you like it stronger.
3. Serve
Remove the bag, compost it, and pour your cold brew over ice. Add milk or syrup if that’s your thing. Store any leftover brew in the fridge—it’ll stay good for up to a week.
Need Ideas?
Here are 3 ways to remix your brew:
-
Cold Brew Tonic – Equal parts cold brew and tonic water, splash of citrus
-
Iced Mocha – Cold brew + chocolate oat milk + ice
-
Coffee Over Ice Cream – Cold brew + vanilla ice cream = grown-up affogato
TL;DR?
Mega Bag. 1 litre of water. 12 hours in the fridge. Done.
Your summer iced coffee routine is now 100% faff-free.
No Mega Bags (Yet)? Use 3x Regular Bags Instead
Still got our Big FAFF Single Origin Coffee Bags lying around? No problem.
Cold Brew Hack (Old School):
Use 3 regular FAFF Coffee Bags with 800ml water. Follow the same steep + chill method above.
Not quite as strong. Not quite as smooth. But still faff-free.
Step 1 -
Place coffee bags into your jar and fill with 800ml water. Give it a stir.
Step 2 -
Place your jar or jug into the fridge for 12-18 hours. To check if the cold brew is ready you can always give it a taste - it should be nice and strong! Once the time is up, remove your coffee bags and place them into your compost.
Step 3 -
Mix your cold brew in equal parts with your choice of dairy or alternative milk like oat milk. You can adjust the ratio of cold brew to milk if you want your iced latte to be stronger or weaker. This is the time to add some sugar or syrup to sweeten it up too if you like.
Once you've finished with your cold brew it's best to store it in the fridge. It should stay good for up to 1 week.
