Quamar Q50P/doserless habits!
« Reply #25 on: 09/08/2017, 02:05 PM »
Yeah delicious that one :)

Okay so an update for those tuning in (sorry.. I feel like I've been posting an insane amount, it's only because I've been quite unwell of late and have had alot of time off work, so being stuck here have gone a bit insane, hope that's okay )

I'll try to not make this an essay post

Whipped out the Harrar beans 7 days post-roast, and pulled 8 shots. This time I really mainly focused on changing the grind as the only variable (the first shot i changed from 20g to 22g only because 20g was too shallow in the basket). Here's how they went:

Distribution remained the same: I taped the push switch down, distributed evenly whilst grinding, 3/4 way collapse, horizontal taps to level, collapse, straight tamp.

-20g gr1.4 y16g 40s (great pour, obviously very slow haha, but thick and delicious)

-22g gr2.3 y42g 20s (horrendous pour)

-22g gr2.3 y42.5g 20s (less spurts, more central pour)

-22g gr2.2 y42g 24s (pretty good pour)

-22g gr2.2 y42.3g 23s (nice pour, few spurts)

-22g gr2.1 y34g 30s

-22g gr2.1 y42g 28s (little harshness)

-22g gr2.1 y37g 28s

All in all a great session, it seems a grind change equals about 4 seconds difference in pour (am not sure what happened with the last shot though which went a bit slower...)

I guess each grind setting needs a little time before it sets in. But much happier with this result :)

(Also measured total wastage by the end of the session, ended up wasting 59g all up, which makes sense due to grind changes and purging)

Great Stuff Simon!  One hopes you didn't drink all 8 shots....  ???

Haha thanks Brett! Errrrmm..... maaaybe... haha.

Well technically they were 8 doubles, so that's 16 shots of coffee, BUT I drank only half of each beverage mostly, and chucked the rest into a cup to put in the fridge (potential iced coffees!), so technically 8 were drunk... :S

Another session (I feel like this is a journal now haha...)

DAY 8 POST-ROAST
#distribute evenly whilst grinding, 3/4 way collapse, little horizontal taps, *adding stockfleth, collapse, straight tamp

-22g gr2.1 y29g 30s (great pour, nice, a little harsh tasting)
-22g gr2.1 y36.6g 30s (pretty good pour, nicer)
-22g gr2.1 y32.7g 30s (little spurts, pretty good pour otherwise)

#Go a bit coarser:

-22g gr2.2 y40g 25s (brighter, much nicer)
-22g gr2.2 y44.5g 23s (went to a nice central pour, then spurts! ??? Still quite nice)

#add nutation to slow down pour and hopefully get rid of channelling spurts...

-latte 22g gr2.2 y50.6g 25s (??????? Pour was a little weird and fast, few spurts... Latte was quite nice though.. only a little bitterness present)


A little frustrated at the strange results.. the thing is I kept everything the same. Am pretty fastidious with keeping technique EXACTLY the same..

I only added nutation because there was clearly some channelling with the spurts that were showing, but I have NO idea why it was a faster pour after nutation... nutation always slows down shots significantly from my experience!

The Harrar beans are 8 days post-roast, so perhaps it still hasn't quite stabilised fully? I'm surely surely hoping this is the case...

Will try again on day 10 or 11 perhaps....

Any thoughts are much appreciated..

There is this funny old coffee-lover's tale that says grinders don't settle themselves down and become consistent until at least 10kg has been through them. By that time they're seasoned, settled and so is the owner! Whether it be the machinery or the user don't be too frustrated. We've all been there and we're bound to return!

Hahaha nice I like that...

Thanks heaps Brett appreciate that very much. Yeah it's a secondhand one, probably done about 15kg or so, am just not understanding what I'm doing wrong here... I think I may be too used to single dosing with my ol Rocky grinder and the ability to easily change grind/change dose and know what's gonna happen. Not used to having the hopper full and dosing that way, so perhaps my expectations are too high, and I need to work on consistency more. And getting used to what a grind setting notch change will result in and how much to purge etc etc...

Just need more time and practice with it I'm sure. And I'm sure I'm overthinking it, and need to spend more time at each grind setting.

Thanks mate :)

Simon......mate, step away from the grinder and take a deep breathe.

Playing with coffee that is too fresh or in it's final "wobbly" stage before stabilization is fraught with frustration.

You are trying to work with an Ethiopian natural and these can be terribly challenging to dial in consistently after 7 or 8 days. Think 12+ days or more. Harrar's are probably the hardest to dial in......consisting of highly variable screen size and densities.

If I was you, I would be looking to play with something that has perhaps more consistent in screen and density - like a Colombian or a Guatemalan. Softer beans like Brazil, Sumatran, etc. can be difficult to get the shots consistent if the bean itself was not processed or roasted well.

Focus on harder, dense beans with plenty of age so you can eliminate the coffee from the variables.

Haha thanks for that mate will do, wasn't aware of the Harrar beans' need for much longer rest, and the trickiness of dialing it in. Will wait until day 12 post-roast anyways.

I was thinking of roasting up some India Elephant Hills AA beans soon, would they be a good option to smash out shots and nut out the grinder do you think?

Otherwise I have greens in PNG Mt Ambra A (washed), or Honduras Montana de Comayagua if you think they'd be better suited... Or I'll just order in some not-me-roasted Columbian beans

Appreciate the help mate

Order a bag of beans from mycuppa (same as above!!) mate. Rest them then try to dial your grinder in. They are always a go to for me when I am frustrated with what I’m roasting. Always very consistent quality.

Great thread and good advice.  I was so very ready to go the whole hog and grab a... forgot... belt drive, conical burr opens grind chamber... forget.  Seriously expensive, import only and trashed on forums by the select few owners.  A K10, a paint brush and I'm happy.... for now...... KISS

Love my K10 Coni WBC.

Found it... Versalab! Singly the worst website in the modern era but perhaps the best grinder!

Oh yeah, Versalab. The space age coffee grinder that doesn't really look like a coffee grinder. They do that crazy 3-headed thing don't they?

That's it! I considered one but support is a long way away!  Also I don't think the difference in the cup will be better enough to warrant the hassle.

No essay today haha, but just a little DIYing fun! The flexible metal strip across the front of the chute snapped off (probably from me constantly bending it back and forward to clean the chute). I found it really helpful with eliminating static and also in holding back the grinds from shooting out fast, as without it I found it made a bit of a mess haha.

So I pondered a few possibilities, dusted my hands, and bought just some ol 0.9mm wire, cut it up, twisted it round, and viola! Works very well in eliminating mess, and not only that, quite easy to move out of the way to clean the chute (my original plan involved magnets, double sided adhesive strips and slicing up metal sheeting, so this is much simpler haha). I slotted the ends of the wire inside the holes left from the finger guard thingo I removed, seemed to just all fall into place.

Just thought I'd post this for anyone else in a similar predicament, there always seems to be some sort of solution haha.

Haha, yeah the finger guard never made sense to me, completely blocks the ability to clear the chute (if one loves doing that sorta thing hehe). Obviously it's there for safety reasons I guess ;)
