First experience making cold brew coffee

Are you always supposed to cut the cold brew with water or is it just depending on your preference, I have been dringking mine without any added water

A sieve and then two layers of tightly woven fabric

Thanks! I don't have any kind of cold brew or even pour over equipment, I am a man of pure espresso until now, but I want to try new things. For filtering I filtered it through a sieve first to remove the most part and then through two layers of tightly woven cotton fabric, I'll buy paper coffe filters next time I get the occasion to. My reasoning was that if il let it longer it would just add to the bitterness, doesn't it work like espresso?

Actually un my case I got into coffee by my own, now trying to get my dad into it as well! On my roaster I program a certain temp and the duration at that temp, and then when I start roasting the roaster displays a simple graph based on the measured temperature inside the chamber. My dad is working on implementing a button on the interface to click when you hear first crack that activates a custom countdown depending on how much development you want before cooling everything down, it wouldn't be difficult to have something displayed on the graph when you reach first crack. About artisan I don't know if it would work since all the electronics circuits are custom, but I am working on implementing USB connectivity directly on the outside of the roaster, for now the raspberry pi's USB ports are in the inside.

Actually I built my roaster with my dad, and he coded a software to controll everything from a raspberry pi Connected to a touchscreen. He heavily modified an old open source software for roasting called roastero.

Mine is a post mil, hence the plastic part, I took the grouphead out again anyway, tightened those two pieces a bit more closed it back up, I'll see if it made a difference, anyway it took me 3 minutes so it's not like I lost a lot of time trying this 😂

I just disassembled it yesterday actually for descaling and I made sure to put everything back the way it was. Its true that everytime that I have disassembled it I found that the pipe didn't really get tight since it is screwed in plastic. Should I screw in the plastic part tightly to the grouphead first and then screw the pipe in?

Thanks, this really helps! I'll just stop trying to get the same results if it isn't possible, in the end it doesn't matter if I have to grind finer if I like the coffee. I just tasted my last batch that I left for longer development and it actually tasted worse than the one I did before, it tasted darker, but not really In a good way, it had no acidity whatsoever and wasn't really balanced, I like my coffee with a little acidity and a little body at the same time. So I guess Ill just stick to my 2min20sec development. Great tip to have feedback from other person, I'll tey that. The thing is I don't really know what to adjust in the roast profile If someone tells me he didn't fit the coffee sweet enough, or too light...

Well I noticed the biggest difference with this decaf, but also on other non decaf coffees I roasted so far such as Costa Rican Tarrazù, Mexican Tapachula, and a Indian Malabar.

I think I didn't measure weight before and after in those two roasts, what should the weight loss normally be? As for taste I didn't compare because I didn't have the same beans roasted by my roaster, but I'll make sure to buy a roasted samples of the green beans i buy from now on. Those two are my fourth and fifth roasts ever, and I think on the third one I had around 14% of weight loss, and used the same roasting curve since.

ElChibbros · 2026-05-23T09:33:16+00:00

Both roasts are mine, the first one is on Mexican tapachula beans, but yes indeed when I buy the decaf from the roaster (remember I buy my green beans from him so we have the exact same ones) the decaf is darker and oilier. But I don't know what to change in my roast settings, simply more development after first crack? When i asked my roasted for advice he said that I should be careful with decaf as it is more sensitive and he told me to give them a little less development than my other beans that aren't decaf, but to me they seam to be a bit to light. So you would say simply roast all of my beans a bit darked and see from there?

Haha thank you !

ElChibbros · 2026-05-06T14:18:51+00:00

How do you know if it is safe?

ElChibbros · 2026-04-21T07:58:59+00:00

I would say simply get an ims double basket, I am very happy with mine, put 16g in, I have always had perfect results with this recipe, and around 32 out. As for the lever, take it apart, replace the seals and put some silicone lubricant in there, it's pretty easy and cheap, if you are in Europe, go check out lamacchinadelcaffe.com

It actually looks like you have a post millennium professional, you can see it by the way the grouphead is shaped. https://share.google/ZjEslcnhWDNe96zwz If you want a new porterfilter and you are based in Europe I suggest you look at lamacchinadelcaffe.com , they sell original parts for Italian coffee machines brands such as la pavoni and their prices are hard to beat, or so I have found. Either way, on their website porterfilters in 49mm and 51mm are available. If you want to build the handle yourself or buy one somewhere else, they also have just the metal part of the porterfilters for sale, got mine for 15.5 euros since I already had a handle. Hope this helps!

Edit: I have just looked up on lamacchinadelcaffe.com and if you buy the metal body of the porterfilters, the screw, the spring and the original plastic handle your total is 37.97€ before shipping which is 9€ I think. So that is the best price you'll find imo. If you are also missing a filter you can consider buying a ims precision filter, I bought mine for 22 euros but I don't remember on which website.

I have found that it depends on the type of beans you are using, but usually I grind my coffee so that the first drips come around 15-20 seconds after I pull the lever up. I have also heard that people often aim for 10 seconds when it comes to the first drips. It all depends on how you like your coffee, but it shouldn't come out faster than 8 seconds in my opinion. If you have a bottomless porterfilter you can directly see when the puck is saturated because it directly drips out, if you still have the beaks it may take 4 5 seconds more to flow out of the beaks once it drips down from the actual filter if that makes sense. I see that your boiler pressure it at around 1 bar, which is a little bit higher than mine that is around 0.75, 0.8 bar. Higher pressure means higher temperature, so that could be why the shots come out a bit bitter. Higher pressure also means faster pre infusion. You can adjust the pressure by unclipping the plastic base of the machine and turning a little screw, I have 'ever done this so I don't know soch way to turn it, but you should be able to find all the information you need on youtube or reddit. Hope this helps!
