Filter brewing: improved with duct tape

Posted at 2009-08-04 23.56

Dave Walsh, in his article about the Abid Clever, highlighted a problem I had with the theory of filter coffee: the variables you want to be directly proportional to one another (contact time and grind size) turn out to be inversely proportional.

I wanted to try a filter brew of Has Bean’s El Salvador Pacamara but was reluctant to mess with the grind to get it nicely to a 4-minute extraction. Enter duct tape: I stuck it over the holes till the three minute mark then prised it back for the final 30 seconds' drain.

Honestly, I think I got the grind too coarse: I had been aiming for something akin to James Hoffman’s cafetière grind but wound up with something coarser still. Consequently, it was a bit on the weak side but the technique seems to show great promise.

    What a surprise reading about hasbean coffee on pdo ;)
    A Cafetiere-grind won't bring you anywhere near 4 minutes in the filter (I guess you already know that one), but have you seen James Hoffmanns' Filter/Chemex-video? Very helpful for me back then - as was his French Press video (he once made one for us visiting that style and it was mind boggingly perfect).

    btw, what grinder are you using?

    Hi Lukas. I should perhaps filter my planet feed… Still, no matter.

    Yes, I definitely need to grind finer: we'll see if that has the desired effect. I don't want to updose: I'm not going far beyond 60g per litre.

    I've watched practically every one of James' videos: always full of useful stuff.

    At present, I'm using a wobbly hand-grinder but I have my eye on a Mazzer Super Jolly like we have at work.

    Hi Stribb, thanks for the post. Please don't filter your posts for the planet’s sake. PDO and such are supposed to be aggregations of the personal blogs of Debian-related people: there’s no charter saying the content must be about Debian all the time. I (and many others) find it more interesting and colourful to read about the lives of the people involved.
