There's probably too many websites depending and what level you are currently at and how deep you want to go . Google is your best friend
Rule of thumb, grind only as much as you need at the moment. If you're making one cup, grind enough for one cup
Ground coffee loses flavours within minutes after grinding.

Curious ques: If you have a grinder, why the need to grind ahead?

my kitchen top has limited space, that's why i plan to grind it in one go and keep it in storage, otherwise keep kena complain

On the other hand you might get complaints when your espresso doesn't come out right because the grinds are stale

Hi coffee-loving people;

I've managed to get my hands on a range of green/raw coffee beans.... too much for me to consume personally.

Stuff I've got:

- Vietnam Robusta
- Brazil Peaberry
- Tanzania AA Mbozi Region
- Brazil Yellow Bourbon
- Brazil Obata
- Ethiopia Yirgacheffe
- Nepal Mt Everest
- Kenya AA Top

Please PM me if you are interested.

or on the other hand you might complain to coffee roasters that their beans/coffee taste so stale/bad.

in that case its cheaper to get powered coffee from retailers, like "aik cheong" "nescafe" etc. no point wasting beans that you find "average" / no difference from kopitiam coffee.

just my 2 cents.

Woah!! have fun Profiling these amazing beans!!

to PM for green beans or roasted beans? coz i don't have roaster nor popcorn maker.

I've just started roasting with a popper, so I'm not confident enough to roast for you. As such, it will have to be green beans for now.

If I can get consistent roasts (probably after I hack the popper with a PID, temperature probes, airflow control, etc) I'll get back to you.

I must say that roasting coffee is an amazingly fun process... very sensory (sight, sound, smells), fast & involved (absolutely CANNOT take your eyes off during the entire process!!) and you get absolutely FRESH coffee!! I have NEVER seen so much crema!

.... and did I mention ECONOMICAL? The popper will pay itself off in two months or less, based on my current consumption level.

Strongly recommend everyone to try this out!!

Thanks. But still there is a few more touch up to be done like covering back the knob hole and some paint job since there is scratch mark on the cover. I'm imagine if i can put this kind of art beside my machine, it would be awesome.



Same boiler but different internal parts build (Namely, Piston & Body, i believe is the opening of the internal part would be a bit larger space when lever are push to back). i ran a bench mark test with youtube video vs my actual brew time... not sure how accurate it is... but definitely it feel quite fast....

But i still paranoid about the hissing sound made when the boiler is heating up.... feel like something is leaking inside or could it be the hissing sound coming from anti vacuum release vapor that turn into water touching the anti vacuum hot body.... Anyway im still waiting for my pressure gauge to measure the opv .... guess i had to wait for 2 more weeks.

good start!! you are on the way to become a pro!! for me i stay in a condo so can't afford to roast as i heard the coffee smoke will ring the smoke alarm!! do let us know once you are ready to make some profit from your special blend!!

And yes fresh coffee always have thick crema but i do notice after 3-5 days or so its the best cup ever i can say its the peak of the beans and the flavour gets bold!!


hmmm on the hissing sound is it long hiss? as it should be hiss (1-2sec) then the valve will be closed/locked. and there shouldn't be any vapour? unless its really close to the boiling water which the valve maybe touching the water which it shouldn't. anyway I'm not too sure as I've not mod it before, just base on my own analogy. because "hiss" happens when the pressure is going up then it should lock.

How come I never realize there is this thread for coffee lover?????

You can fashion a small cup and cap to catch and block/divert the water when it spids out...I've used aluminum foil...it will evaporate away in da cup.. .

You can do a flow test to set the opv in the meantime...

It is normal for the anti vacuum to release vapour and some spritz of water when it close to boiling point and that is the function of it. It act as self release pressure rather then normal practise where you had to manually open the steam wand while boiler heating up to release some fake pressure before close back.


Hissing sound happen on the initial warm up when close to boiler point or machine almost finish done its thing and ready to be used, it continue on for a while until after a few round of disposing through either the brew or release some steam then the hissing stops.... i assume it could be from the anti vacuum .....


Yeah, It would another great idea mod to stop the water and vapour from flowing out damaging the surrounding. Btw, seem like you had already install the anti vacuum on your machine. Do you get hissing sound like water touching the hot cup or anything like that when the boiler almost done with the heating process ?

For OPV, I rather wait for the gauge but i heard it is already pre set to 10 bar straight out from the factory, means to say you don need to adjust anything. Just fix and used.

Mine's not the Oscar... Comes with it already... My hissing sound is just before the anti vacuum valve sets...

Could your hissing be some of the water hitting some hot surface and flashing off sound?

BTW...nice mods... I prefer the knob to I can have slow steam to steam buns

hahaha Steam buns!! thats first!! i use it to steam my cold brew if i want to drink hot long black minus the acidity!! Awesome too try it!!

Yes, Hissing sound came from water hitting some hot surface and flashing off sound. I tried to check but there is no leak found. Last time i encounter 2 leak but was solve ( one from the pstat leak from T-piping and another is male to male fitting on the steam due to gap).

I also did a few verification, like machine water intake, how fast the heater kick in, steam power, brew flow. seem everything looks normal to me. Just only the hissing sound....

Used steam wand to heat up bun.... lolz....

Oh I just order a new one could save a few dollars. But any way have a few question to you. I've read a review http://jonsguide.org/best-home-espresso-ma...appuccino-maker And found it does not possess the auto shut down option. What that means?

...useless blog/blogger...

Doesnt matter.
Probably auto shutdown when the water is running out
Just make sure u turn off your machine , dont leave it open overnight

Hi guys, not sure if this is relevant to the coffee over thread but I'm looking for the MCT oil, which is one of the component for the Bulletproof coffee. Any idea where i can get it in Malaysia?

Cheers guys
