Does anyone grind Vietnamese coffee beans on HG one or kopi grinder? I find these beans very very oily.
So I m not sure if I have to perform a wipe/clean after such grinds.

The disadvantages in how much more oxidation exposed, and the lengthy process outweighs the benefits of the burr size and rpm which has negligible benefits for domestic use.

I think a lot of people are very confused here. Big burrs and slow rpm are more important to people who grinds continuously or the old doser/manual grinders which could only grind non stop.
The bigger burrs and slower rpm reduce overheating that leads to dissipation of aroma.

Present ODGs has a gap of time between grinding to reduce overheating. In term of preserving the coffee and it's content of aroma, ODG is certainly better as the coffee is less exposed to fresh o2, particularly in powder form.

Hand grinders are good for one who appreciates the ritual of hand-crafting their coffee, or for those with a tighter budget. But it won't make a better coffee, the science don't agree in that.

Haha thanks for the info! 2 left! Yay!

Actually the Titan project to beat mazzer in a way find other grinder like cimballi max, compak k10wbc, mcap mxk to yield better taste. However I think it's best to take those reviews with a pinch of salt as coffee taste is subjective. If these were tested by Singaporean tastebuds, May be it's possibly more "relevant" to us. (They didn't have international tastebud in their test setup.):s13:

Indeed. The sample size and number or participants is too small. Not to mention Jim Schumann only one 1 type of coffee. The reviews are fun to read but should not be taken as scientific fact but rather to share and generate discussion.

Once beans are grounded, how long for the oxidation to take place b4 one could taste the difference?

Anyone here heard of the Babbie's rule of fifteens?

Congrats to those who bought the hg one.

I read the mazer burr is not seasoned not sure what it means and the effects. Sorry newbie here

Chanced upon this yesterday. Interesting presentation by the various WBC competitors. One thing for sure, Matt Perger is a natural showman

Good qn though I'm not too sure either apparently newer burrs takes time stabilise the grind setting. also newer burrs have more friciton so harder to grind..

the mazzer burr is bead blasted to reduce friction i think. The other TiN after market burr is coated with TiN for corrosion resistance and less friction. TiN is quite hardwearing but i doubt makes makes difference i the cutting quality.

Thanks for sharing. Thumbs up for daft punk :s13:

Matt perger seems enthu in large coffees compared to espresso. Frozen espresso cups:eek:?

But interesting performance from all 3.

I think the main difference is that the hg one is now stepped. Looking forward to using it and making comparison with the compak.

I don't think changing to stepped matters very much. Those are micro steps imo. You're certainly not gonna find yourself wishing you could dial in between steps.

IMO, the biggest change is the locking mechanism for the burr collar. Pre-2014 models like mine, the burr adjustment collar will tend to shift/move when grinding hard beans during seasoning period. The new models definitely won't have this problem.

Fresh burrs from the factory doesn't have smooth cutting edges. The edges are jagged which you can't see with the naked eye. When first put to use, beans are likely to be crushed rather than being sliced. Over time, the beans will act like honing rod and begin smoothing out the rough edges. Once the edges are smooth, you now have a seasoned burr and you'll notice that you need to grind finer than b4.

Yep I find stepped easier for remembering settings. Do u grind directly into portafilter or use the blind basket?

If you remember watching my vid, you'll find that I do neither of those.
Grinding directly into the portafilter requires their Cradle, which I don't have.
Grinding into the blind tumbler, I have difficulty doing the WDT coz of the knob in the middle.

anyway this is also quite interesting, using an espresso machine to make a large coffee (long black). By matt perger and mahlkonig.

Mahlkönig Releases The Definitive “Coffee Shot 101″ User Guide

While matt perger did some tests to show superior extraction yields with the mahlkonig ek43 i think its good to remember that his face is on almost every ad for the ek43.

Tried the "Coffee Shot" today. 18gm coarse grinds on my HG One. I chickened out and used my double spout instead of my usual naked. Pulled abt 250gm out in 45secs. Also made a cup using the aeropress for rough comparison.

"Coffee Shot" tasted weak and watered down. The one with the aeropress, well, you can rarely go wrong with it.

I doubt I'll ever use the VBM for my brewing needs. Thats a different story though if I own the EK43=:p

Yep i tired it with 200g of water instead of the recommended 300g. I think 300 would be too watery for my taste. Even the 200g was too watered down for me. I wonder if weak coffee is his preference.

Yah I agree aero press taste better. No need to measure so much too. I find using the default fine grind of 2 scoops and 2 ounce shot with water added to too up taste better.

If you want to drink an americano, would you use the aeropress or your espresso machine and add water?

Usually I make an espresso and add water and sugar. For night drinks to last longer.

Aeropress also can. The default instructions makes a very thick and strong coffee which I always add water and sugar to dilute.

Both taste different. Americano made by espresso has more tea like acidity of a certain kind and elegant structure I dunno how to describe and need to taste and compare to understand. It's not muddy.

Aeropress style Americano has a more rounded body and I would dare say more earthy flavours. Like a very strong French press with no muddies.

Just checked. The Pharos is back in stock in case anyone's interested! Don't miss out on this piece of cult classic espresso equipment.
