      Done! I'm assuming you used the paper filter in the aeropress right?

        awesome job!

        I see you fit the dripper in reverse/backwards to what I did! Does it work ok?

        looks great.

        I use a metal aeropress filter (s-filter) in the bottom) and two paper filters cut down on top of the bed of coffee. (you really really need filter papers on top of the bed so you get an even extraction. A single paper filter would work in the aeropress cap if that is all you have

          Ah... Ya it was tricky to fit the dripper on. So far so good. I only used one paper at the top. Will try 2 next time. I have the metal filter. But decided to go for paper today. Getting the misus to cut out a cloth set (top and bottom) using the beanbay bag :P

            Dang! Should have seen this vid before I tapped mine up. Might upgrade in future. Lets see how this one pans out first.

              My wife actually had a weird but valid question about cold drip as I was doing this. "Didn't you say that ground coffee goes stale in minutes?" -.0" I was like "yeah... But... Em..."

                  Mate, you could be famous! Like Corretto roasting, this idea could have a name as well... The JamesM Cold Drip Rig... or something

                    hah, flattering, but it's not my idea, there are other folk who have made their own drip towers!

                      I don't get it... After coarsening the grind and increasing my flow rate, I believe a little faster that 40/min. I still get a drip rate of 9-10hrs are my markings on the Macap wrong :S

                      Even so, the 10+ hour first drip I did tested really good though! A lot smoother than cold press for sure! So I wonder of I got it down to 6-7hrs what different would it make? Brighter?

                      Stats:
                      70g coffee
                      Normal drip filter grind (I think...)
                      700ml water
                      40+/min drip rate...

                        On my last batch I did 100gm grinds and the chamber started overflowing with water. I had to pull the drip off and wait for it to settle before putting it back on, then it was fine..

                        Your recipe seems ok!

                          Interesting... How did it overflow? Too fast a drip rate?

                            Same rate but somehow choked up in the grinds and started to fill on top with water. Once I let it settle and put the Dripper back on it was fine

                              I was at a coffee roaster in a small NSW country town and they had a setup almost exactly like this. First sip was very bright, second sip good body and there was a bit of earthiness to the dregs. Not bad overall!

ID:	733619after you showed us your rig james i've been itching to try it out myself!
                                just got a irrigation rig from bunnings today and trialled fitting it into a bottle cap - the irrigation rig seems different to the ones you have and a little more similar to what we see on commercial cold drips with an adjustable tap at the side! now to find a stand to fit it all into!

                                brokenvase, is your drip rate slowing towards the end of the extraction? could be that the decrease in water mass above the dripper is slowing your water let down rate and slowing the brew?
