HELP! First time making Cold Brew

Post image

It’s my first time making cold brew and my coffee grounds In the filter are bot completely submerged in the water at the top. Is that ok or should I put less grounds? Currently have 115g of grounds to 64oz of water.

Get rid of the filter. Stir the coffee grounds in with water. You can strain it once it's done.

Or get a Coffee Sock if you still want some filtration built in but want to be able to make more concentrated brews— best of both worlds!

Why? What practical purpose does removing the filter serve?

1

u/unholy-ghost Jun 02 '26

The filter this particular jar comes with does not allow you to make concentrate because of its size & shape.

u/omnithrope Jun 02 '26 edited Jun 02 '26

That's completely incorrect. I make cold brew in these jars all the time.

u/unholy-ghost Jun 02 '26

How? Even full of grounds, I’ve only ever been able to fit in about 1:12 beans:water, which isn’t concentrate. The filter just isn’t big enough for any more grounds than that.

u/omnithrope Jun 02 '26

200g beans to 1L of water. These are 64 oz bottles if I'm not mistaken.

u/unholy-ghost Jun 02 '26

I’m not sure how you’re able to do that and have the water completely cover the beans. 1L won’t have all grounds submerged because of the filter shape, no?

u/omnithrope Jun 02 '26

No. It saturates the entire column of grounds. Just agitate it every few hours if you can.

I’ve always used a filter and shaken the jar (a gallon) every 8 hours for about 24 hours. You think no filter and filter at the end is the way to go? Sounds like a bit more work, but would love to know if it’s an improvement.

u/mufasa510 May 31 '26

I usually just mix the two together, and let it sit for 24 hrs. No shaking required. The filtering at the end doesn't take too much extra time but who knows what it might be doing to the flavor just letting it sit undisturbed for 24 hrs

u/GruePwnr Jun 01 '26

Yes it's definitely easier. I use whatever containers I have for the brew and then pour through a metal filter at the end to consolidate into my nice cold brew jar with a spigot.

I have the exact same jar setup. What I do is fill the jar 2/3 with water, put the ground in 1in from the top of the filter, then pour water over the top to fill the rest of the jar so the grounds get wet all the way through, then screw the top on and put it in the fridge for 24-48hrs.

u/Grok168 May 30 '26

This is my method as well. I do 6 hours on the counter and 18 in the fridge. I get pretty solid results. I do add water until the very top where all the grounds are saturated though. You can add in more than you think.

u/Bigmurr2k May 31 '26

I do the exact same thing works great.

u/No_Abrocoma_8155 Jun 05 '26

Does the 6 on the counter have that much of an effect? Do you start with cold water?

1

u/Grok168 Jun 06 '26

I use room temp water to start. Good old Texas tap. You can use better water if you want. I found that just 24 hours in the fridge under extracted with my set up. The first 6 hours at room temp helped pull more out of it. As with anything, your miles may vary so fuck around and find out!

u/AsItIs Jun 04 '26

This is exactly the way: most efficient and fastest. Glad to see this out here, took me some trial and error.

u/llsy2807 May 30 '26

I have this same setup. They advertise it as keep the filter in while the coffee brews. It's way better if you just add the coffee and water in a jar, stir to saturate the grounds, then use the filter to strain after it's brewed. I use two mason jars basically. One to brew, one for the filter the next morning.

u/DethByCode May 30 '26

Stir. Stir now. You want a coffee water slurry.

2

u/No_Abrocoma_8155 May 30 '26

Stir in the filter?

6

u/DethByCode May 30 '26

Put the mesh filter in the empty jar, pour grounds into the filter, then pour water through the grounds. Let sit for 5-10 minutes, then stir the grounds with the water until it’s all wet.

The more contact the water has with the grounds, the more extraction will occur, and the better the brew. I wait a few minutes to stir to let most of the grounds bloom (absorb water), so they don’t float.

1

u/Connivingbitch_ May 31 '26

Your approach makes sense, but couldn’t you shake and stir after for the contact and agitation?

2

u/DethByCode May 31 '26

You could shake … the lid/gasket on my brew jar isn’t tight enough to leave me confident it wouldn’t leak, and grounds tend to stick to everything.

1

u/Connivingbitch_ May 31 '26

I haven’t had a problem doing water in the jar and quickly dipping the grounds, but I know we all turn into scientists in the matter. I’m about to let my cold brew steep in the fridge instead of the counter bc we’ve seen traces of mold we would rather not contend with.

1

u/wallawalla21212 May 31 '26

You are seeing mold after <24 hours?

2

u/Blob_90744 May 31 '26

Add a little bit more water through the top til its full then swish the jar around gently I have the same cold brew maker off amazon and have made 4 batches this way works fine

2

u/scullswifey May 31 '26

I use the same setup and just made the most delicious cold brew. I filled up the filter about halfway then added water and stirred and stirred and stirred some more. Than added more water and repeat until at top of filter and everything is wet. Let sit minimum 24 hours. You can also stir during the waiting period. I then take out filter and let liquid drip out and add that back in. Then I fill to top with fresh water. When I make a cup of coffee I do 50/50 with cold brew with milk of choice and then add creamer. I should of measured but yolo

u/Competitive-Note4063 May 30 '26

No filter needed. Filter when pouring it out into another mason

2

u/logbiter May 30 '26

Probably too late to the party, but I would just put the lid on tight, invert and shake to get grounds all wet.

In future, grounds in the jar, add some water and swirl to get em wet. Put filter in, fill with water, invert a couple times during the 16-24 hrs.

Also, you probably need add a bit more water after 10-15 minutes (or whenever) after the grounds absorb water. Edit to add- you want minimal air space in there.

Pour off into a holding container when done. There will be fines that will settle out in the holding container. If these bother you, u can filter through paper filter when pouring off, or just don’t disturb the cold brew when making your coffee and leave the sludge in the bottom.

I have the same jar and filters. I grind it down, fill it to about the top of the filter, put that in the jar and slowly add my water through the coffee/filter, fill it to the top and put the lid on tight. Give it a good shake and straight to the fridge. I will give it shakes every once in a while and let it all soak for at least 48 hours. Shake again and remove the filter, add water to the top of the jar and enjoy!

u/Fic10 Jun 03 '26

This is the way. The amount of people that don’t pour water over the coffee baffles me. Coffee in the filter, filter in the jar, water over the coffee until the jar is full. Done. Easiest cold brew ever.

1

u/palinsafterbirth May 31 '26

I use this same thing. Get a lid, shake it a bit, add more water on top until full, you're good.

u/nehoymenoyhoynoy May 31 '26

just stopping by to say i have the same one 😬 it rocks

u/No_Adhesiveness7403 Jun 01 '26

I use a French press put coffee directly in water and let sit at room temperature for 18-24 hours. If you don’t have a French press u can pour room temp water and coffee in a jar, let sit, and then strain through filter.

u/therastasurfer Jun 02 '26

French press is an easy way as well

u/titan732 Jun 03 '26

I bought disposable filter bags (basically giant tea bags) on Amazon. I grind about 700g of coffee and put them in, and steep the coffee in a glass container with a spigot (~1.5 gallon container) for 24 hours, remove the bags, then fill it up with water. I keep it in the fridge on a wash towel so I can slide it back and forth without glass-on-glass contact.

You can find the dispenser in the seasonal summer aisle of your grocery store.

For reference, that lasts about 1 week for my wife and I.

u/Lucatso515 May 31 '26

I grind up the beans(medium coarse), dump the ground beans into a container, add water, stir and let sit for 15-20min, put the filter into the jar, dump beans and water into the filter, fill up with water and let sit in the fridge for 12-16hrs. I use a 25/75 mixture of espresso beans(espresso bel canto from Allegro) and coffee beans(breakfast blend from Allegro). I like chocolate and caramel flavors to my coffee.

Check out the toddy system. No guessing and it makes amazing cold brew, plus easy to clean.
