Hey guys i have a question that has been bothering me for a while now. Why does the coffee to water ration differ between brew methods?

For example, a french press might use 1:10 coffee to water ratio while filter tends to be 1:16 and espresso 1:2. Why is that? Isn't there a sweet spot for extraction, around 20%? And is the caffeine content in all the methods the same, assuming the same amount of ground is used?

Caffeine content explained here

Yes the sweet spot is 20% thus the ratio

Correct me if i'm wrong but doesn't grind size, pressure and temperature affect extraction while water to coffee ratio affects the strength?

And yeah i know i should just do whatever taste the best to me but i am really curious about the science behind it all.
The problem with that comparison in the link is that it doesn't state the amount of ground coffee used. I am more interested to know if different brew methods contain the same amount of caffeine if the same amount of grounds are used.

What is your question again ?
both had its goods and bad....i would choose mignon over sette after much consideration....
Yeah, sette is good, digital, direct to portafilter without wastage and fast..... but the grind is not as fine as mignon....programmable timer ? I can live it .... once set, then all done, you wont need them anymore unless you constantly change beans same goes for the dail, Clump from the grind, hmm what machine doesn't clump ..... fast, well im not doing any coffee bar or shop.... i love taking my time making a cup of coffee i love 

but my consideration might not be agree by some... 

What's the preoccupation with fineness? Once the grinder can reach the level of choking the espresso machine, is there any need to go even finer? Doing turkish?

The thing I like with conicals are the effectively-zero retention.  For home use (just a few shots a day) this is a concern to me.

I think the price is reasonable.... if you do 1 to 1 conversion is it about close to 2k......

one must not forget.... the person who sell you also want to gain profit..... plus order in taxation is not like it used to be, everything now will be charge for high price.... example taken from my friend order his watch overseas last few weeks back and got heavy tax as well.... just for rm500 watch other country price but cost him up to rm900 watch when reaches our shore to his hand....

Anybody bought an Oscar 2? Do let us know where you got the best deal from.

I got few of this bodum glass. Love them. Get it cheap around rm5 each from taobao. I use them everyday. Not easily break.

I searched a bit on taobao, don't read chinese so I'm entirely dependent on chrome's auto translate From what I can tell them RM5-6 double wall glasses aren't original Bodum, they're not even advertised as Bodum, just double walled glasses. The Bodum advertised ones are a bit more expensive roughly 17RMB and higher but still half the price of what you'd get here. Maybe @luvox can give more details.

I'm tempted to get several as well

Rm5 is old price d, 1 year back. The cheapest is around rm7. Not include shipment fees to malaysia. I use sea freight, it is volumetric rate, consider negligible for small item. Cheap one doesnt come with boxes, consider factory rejected items due to unnotice small defect, unless ur eyes go very close to the glass. Original bodum printing at bottom. There is more expensive available come with ori box, price still way cheaper than local price

Haha I certainly had my answer in terms of price and convenience, but I guess I was asking more in terms of reliability, consistency, taste. I have not used Breville or drink anything made with Breville, so asking to see if anyone has good/bad reviews on it. Appreciate your thoughts though 

Harvey Norman sells this Breville for RM3.6k, even with promo RM2,999 but need to purchase warranty forRM500/600 for 4 years.

Other place only cost RM3k 1 year warranty....  big big difference.

Looking at  La Pavoni Professional Espresso Machine with Base by d33pbluez.. which i think will last but i read it needs high maintenance.. hahhaa 

Thanks for all your reply guys. I don't drink long black so much; prefer milk based but trying to learn to drink black coffee as well. I guess it's obvious from my questions that I don't know what I'm doing yet, so would prefer to send in for services instead of DIY.

Thanks bro kuluuluk for the info on the warranty. Something to think about.

I had my eyes on the BES870 when it won Best New Product—Coffee or Tea Preparation and Serving Equipment (Consumer) back in SCAA 2013.
However, after consulting with a few experts in the field from Coffex and Dankoff, they did not recommend it for long term usage -> its always a bad idea to bundle the grinder with the espresso machine itself as the heat generated will not be good for the beans. I took their advice and went for a more recommended BES920, the Dual Boiler.

Been using it for 2 years now, it’s quite reliable, hasn’t let me down yet. Quality of the drink wise from the Breville machine, it tastes excellent, provided you use only fresh beans, fresh milk, and make sure you maintain your machine properly (flush/backflush thing), cleaning the machine, change filter (if required).

If you’re not much of a heavy drinker like me, I weight and put only sufficient beans into the grinder each time, and clear out any remaining beans/grinds every time, I think, the heat from the espresso machine should not affect the beans much, since you will only be using fresh beans, and not leaving the beans there overtime to be heated and reheated by the espresso machine.

They r one year plus old items. Bodum

Bro, have you been overdosing on coffee? lol Lot's of "!!" everywhere. Or maybe you're just a fellow that's always in a good mood 

hi guys, need to ask some basic questions....

1. The coffee bean, is it ok if i fill up the top storage area of the grinder?

2. Is that ok if i grind say 10 cups of coffee bean in a go? If yes i just need to store it in a  air tight container?

is there any website that teach the basic info on making good coffee?

** I have a delonghi kg89 grinder

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

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.

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.
