Now Im all for the hot cup of coffee in the morning for caffeine rush, but it can by quite acidic.

I found out about cold drip/brew coffee is brewed without heat. Instead, the water sits in the grounds for 12 to 24 hours, slowly taking on the flavors of the grounds. The result is a unique tasting concentrate that is supposed to be smooth, full of flavors and with no bitterness. It also has very little acidity.

Think I might have a go with a bodge system:

before taking the plunge on an expensive made system like:

I suspect you can do the same with tea too?

So anyone tried it or going to have a go at this too?

I live in brooklyn...you cant move for "Cold Brew". It appears to be the latest coffee trend.

Quite tasty, mind. It needs to be watered down from "neat" due to the huge caffeine content (heat usually breaks down the caffeine, both in roasting and brewing).

I use lychee-scented tea from jing.com, which makes a delicious iced tea. I put a few teaspoons in a jug of cold water and leave it in the fridge overnight.

I suspect Moroccan mint (ie. 50% mint and 50% green tea) would also work well though it hasn't really been hot enough out that I CBA to try it.

I've tried this a couple do times recently, using waitrose ground espresso coffee which I usually use in the moka pot on the hob.

What type of coffee did you use? How many parts water/coffee in the brew?

Mine was a bit strong/bitter still...

This is what I have been drinking for past few weeks... green tea and egyptian mint (brought a pack of dried stuff back, along with hibiscus too)... its lovely warm, but not tried it cold dripped yet.

Not tried this yet, will be interested to read your findings! If the sun dare shine - cold coffee could be a winner!

Im going to try and source some felt tomorrow, then take a couple of bags of coffee beans across to Finland when I go on holiday on friday and try it at the in-laws as they are massive coffee fans, will report back on my findings and if the filters I have are too small, I will just have to make more coffee bags then shown and see what its it like.

Did you read the concerns about the felt in the link you posted? It sounds like some felt/synthetic felts may have potential health issues.
Just trying to worry you. tongue out

I know, but I will just improvise with gauze and filter paper or something else instead of felt that has chemicals in it.

its going to be a fun process, before I look at getting some chemistry equipment and do this:

Cause Im in Finland for nearly a month and the OHs father is a whizz with wood, Im sure we can knock up the pine frame and source the other toys needed for a little less than $600.

why not just drip it through coffee filters in a funnel?

Presumably because you can make filter coffee in minutes and so I need to make sure it stays in the bottle for 14 hours or so.

Just need to think of a way to get it to drip out afterwards.

So far the update I have is this one:

100g of coarsely cut beans in grinder.
place in jar and add 1 litre of filter water (brita water filter).
Leave for circa 24hours in dark cool place and shake to mix every 1-2 hours so water absorbs it all.
Using a tea strainer and a funnel, place it in a grolsch bottle with what finnish call a patent cork.
Place in fridge for a few hours.

Drink a shot size amount with double to treble the amount of chilled water and ice, due to the very high caffeine content.

Tastes completely different than normal coffee, no/very little acidity, tastes a bit sweeter and nice in the sunshine when warm as it can be drank chilled.

Not tried with milk/sugar yet, but its well worth doing on the findings so far.

Still working out strength to amount of mixer, but its big thumbs up from the Finnish coffee addicts over here and we are taking the rest of it with us to have in russia instead of hot coffee all the time for their caffeine fix.

Wasn't sure pictures of the process were worth it this time, but will do pictures next time once I find a decent clear bottle to place the end product in.

You can brew it in a regular jug, then simply pour it through a funnel/filter after the brew time though?

Struggling to understand the requirement for special kit.

What difference is there between felt and regular paper coffee filters?

I used a coffee/tea strainer instead.

Sorry for late reply, just got back from russia.
