    Macap M2D not quite 18g

    Greetings from a novice,

    I have just returned from a few years in the wilderness with a fully automatic machine and have recently purchased a Isomac Tea Due and a Macap M2D. I am making some half decent espresso, but I would really like to increase my consistancy with precise dosing which I believe should be possible with my M2D. That was the main reason for me choosing that model over the slightly cheaper M2M. Trouble is, with the timer set at maximum (approx 9 seconds), I still only receive 13-14g of ground coffee. My grind setting is producing a nice crema with the first drip coming at around the 6-8 second mark. So reducing the grind to a courser setting is not really an option that I can tell. Im using Grinders Crema organic Arabica beans at the moment. So the question is, what am I missing? I have a horible feeling itis something very simple and I will feel quite stupid when it is pointed out to me, but that is the purpose of me being here, to learn and hopefully pay it forward one day! Thanks in advance.

    Regards,

    Matt.

    Does that grinder have a 'double shot' or similar setting? If not, why not adjust the time down to suit a single shot and do it twice?

    Thats an option I have considered. It just seemed odd to me that I would need to cycle it twice to get a double shot, which I would have considered the most common dose? But to answer your question, there is no double shot setting. I think your solution is the only option. 9+9.

    Does sound a bit odd. Donít have any problem getting enough output with mine. Have a single shot setting (3.8secs from memory) and two double shot settings, 7.5 and 8 secs, normally use the 8 sec setting. The only variables you have for a dose of a given bean are time and grind (assuming nothing else is skew whiff). Try a slightly coarser grind and see what happens.

    Aha! Thanks mjs, Im glad you threw your hat into the ring! Yes it did strike me as rather strange. Are you dosing at ~18g for your double? It has been a while since I did this, but I thought I was on the right track with the grind. It looks and feels right. The espresso looks and tastes good. The only thing that seems off is my puck is generally quite wet. I would like to see a dryer puck, though it is firm and holds it shape when knocked out. Perhaps a coarser grind with a firmer tamp? I did do the tamp press on the bathroom scales to familiarise myself trick. But I could be a bit out. Would rather like a calibrated tamper to take the guess work out.

    I really appreciate your suggestions and ideas folks!

    Matt

    Just enjoying a latte atm, so checked the dose. 8 secs gives me 18.8g at a reasonably fine grind resulting in a very nice texture and crema with just under 60ml in a 25 sec shot. My other setting of 7.4 secs gives me 17.5g, I seem to use the 8 sec setting mainly. I do get a slight bit of variation as the beans get older, normally just crank down the grind a little. Normally use Industry Coffee Fitzroy St blend but have just swapped to Gesha Coffee Co Queens Crown beans that my son and his gf brought back from Perth. Not bad.

    Just out of interest, what age are your beans?

    Thanks again, for that. Yes the beans are new, we go through them pretty quick. Do you have the newest version of the M2D, with the time adjustment on the bottom side? I am a bit disappointed I did not receive the upgraded version with that and the improved portafiller holder and I believe a stepless grind adjustment. Adjusting the time is a bit of a guessing game with the adjustment unmarked and under the body of the machine on mine.

    Apologies, I have had a brain fart over model numbers, I actually have the M4D, so we are talking about different grinders.

    Now that i have my models sorted ...

    The M2D has one timer setting, and maybe it doesnt go long enough to get a double. I’m with Lovey, if you are happy with the grind quality and your shots, the simplest solution would be to just dial it back in time a little to a single dose quantity, then dose it twice.

    hahaha, thats ok mjs, happens to the best of us. Its interesting though, that the times you quoted should still allow the M2D to deliver 18g. I have timed mine to a little over 9 seconds on maximum setting. Unless the M4D has larger grinders and delivery system? I have not really researched that model, so I can't say too much about it. I did however this morning try adjusting my grind one click coarser. Without any measuring/weighing applied, it produced a very large volume (quite nice tasting) espresso in under 20 seconds, with additional force applied at the tamp. So I am at a bit of a loss what try next, other then the 9+9 on the finer setting. I have emailed Macap in Italy to verify what I should do, will be interesting see if I get a response.

    Matt.
