    Sounds a bit like you haven't dialed in your grinder!

    I would place a big bet that is the cause of the end shot gushing.



    I would recommend 16g as a theoretical maximum for a 14g basket without it touching the screen. Try the 5c test as a very basic guide to max dose volume (search the forums for instructions), and don't dose more in the basket than the 5c test allows. Adjust grind to get 25-30 second pour and then go by taste.

    Thanks for the comprehensive reply Bames! I will give a 16g dose a go tonight until my 18gram basket I ordered comes.

    If your wondering what the 5 cent test is check here http://coffeesnobs.com.au/general-co...-unknowns.html

    As I said in my original post and Bames has also commented, overdosing.

    I'm dosing 20g in a 21g basket from a Mahlkonig K30 for 40g out. Different machine to you though.

    I find almost no blonding towards the end of the shot with the K30. With a Mazzer Mini, i was dosing around 21g with a courser grind to avoid worm holes.

    Thanks Luke_G, I am using a brand new Compak K3 push grinder. I initially upped the dose to 20grams as the Compak was choking up a bit and spiting out clumps of ground coffee when I was making the grind too fine, however this may have been just because it was brand new and never had a any beans run through it. I will try grinding finer and dropping the dose down to 18grams when I get home tonight! What dose/basket size do you normally use?

    The coffee is the usual suspect and I think Mal has asked the correct question. Have you changed your brand of coffee recently logankrat?
    I said recently as it is a machine which I have only recently began using, however I have always had this problem with this machine. I have not been making coffee since I moved to WA from QLD a couple years ago as I did not have a machine here, at least not until a couple weeks ago . Therefore i'm not certain it is a problem with the coffee as it is happening with different blends roasted by different people etc.

    When the warmer weather arrives here in WA, I notice earlier blonding with my Bezzera, which is cured by a longer pre-pull cooling flush and very slight finer grind 18g into a 18g basket.
