hi, im new in this coffee making. Just got my self a Delonghi ECOV 311.

I had a few question to ask for help,

1) Milk Forthing:

i pour the cold fresh milk into my milk pitcher (350 ml) , then remove the steam wand foam maker, use direct nozzle into my milk pitcher. Making the milk in the circular motion until my hand feel the milk is hot enough until my hand cant hold it. Problems is the milk after frothing its not dense enough... when i pour into my espresso, its straight away dissolve into the coffee like simply ouring the milk into a normal black coffee.. why? is it because my espresso has only a thin layer of crema? hmm.gif it is because lack of microfoam while i frothing the milk without much air introduce into the milk?

2) Crema

I got my ground bean from Renggit coffee, gring it with my burr grinder to the finest grind, tamp it into my portafilter, on the pump and stop it after 25 sec. coffee produce very less crema. what would be the problem? the bean it self? doh.gif is it much spend much on the expensive bean to get a good crema? normally where you guys normally buy the bean from?


Thank you for the advise~ thumbup.gif

You have almost all the right ideas. Keep it up smile.gif

Milk
Getting it into a circular motion is definitely crucial (also to save your ears from those high pitch noises) but u need to make sure the tip is not too deep. Too low and you will be heating the milk without creating foam. Too high, you will see large bubbles forming. With enough practice, you should be able to listen from the sound itself that you are on the right height. Also, when sufficient microcosm has been achieved, but milk is not yet at temperature, dip the tip lower in to finish to temp without adding more foams

Crema
Beans for espresso is best between 1week to 3 weeks old. Below 5 days, you will get lots of crema but dissipates very quickly in the cup (I call it immature crema). Too old, you get 0 crema ha-ha. How many ml/g do you get with 25sec? Just to see if the grinder is grinding fine enough for you
*
lol, i never weight the bean before start my espresso, just grind it fine, full my portafilter into 3/4 full, gently tamp it then put into my machine... lol.. so basically to make a nice latte art, the espresso must have a nice crema otherwise it wont work for latte art?

He has a pressurized filter...ml/g and 25s doesn't mean much...

Needs portafilter mod...and manual tamp...to maximize it...but to start...needs digital scale for 14-16 g "fresh" beans for a double.

For espresso you don't want anything more than 10 days if possible. For latte you have a bit more leeway...

where to get espresso bean that less than 10 days old since mostly commercial pack most likely more than the time period when they put on sell...

so you mean that i need to get an unpressurised portafiler?

Many recommendations few pages back. We don't buy from supermarket.

For now no. Get fresh beans first. Find a way to weigh your dose.

Crema is not a good indication of quality. It could be, but relying on it is misguided effort at best.

Weigh your shots, time them and taste them. This should ultimately be the benchmark.

ok thx for the info and guidance~😄

I think he is using pressurized portafilter that came default with delonghi, I also got this kind of crema when I'm using pressurized portafilter on my machine hmm.gif
*
so the problem most likely because of pressurized portafilter? do i need to try to get an unpressurized portafilter? pressurized portafilter normally unable to get a thick and nice crema?

hmmm theoretically with pressurized filter  u still can get "crema" without proper tamp/not so fresh beans. But still i would recommend you to test with pressurized portafilter first with proper weight of the coffee bean then only depressurize it if u want to seek for more precise taste of the espresso.  smile.gif

hehe, alright ill weight it first before trying next step, thx yo😄

jz now i try to make another try and error, found out that i grind the coffee too fine, over extract and strain my machine which is not good shocking.gif . I would like to ask normally how fine/coarse do you guys grind the coffee? i just realised that very fine coffee is only suitable for depressurized portafilter.. hmm.gif

That's the exact problem with pressurized baskets. You want the coffee to be the restrictor to generate the pressure but instead you have this quirky spring thingy in the portafilter that's doing this. So if you try to grind finer, the coffee grounds will resist the incoming pressure and the resulting output from the bottom end is a lower pressure liquid (but exactly the coffee you want!) which is unable to push thru the spring to exit to your cup and so you end up with a choked machine

Without the coffee being the restrictor however (grinding coarser) you're not going to be able to generate real sweet flavorful crema unfortunately

Again, you want the 9bar pressure pushing through your COFEE to generate ~60ml of coffee within 25-30sec for a double shot and not instead to push against a spring in the portafilter

Latte art however can be done without proper crema. You could get away with nescafe and a few shakes of cocoa powder on top before the milk too smile.gif

A very good knowledge notworthy.gif

is it depressurized basket confirm can make a think crema with fresh bean or it still depends on other factor as well? i had read some forum ppl did complaint not all depressurized basket can get such result too... so at this moment i think ill just stick to the default basket first, try to adjust the coffee to bit coarse than jz now.

I thought making a nice latte art will need to have a thick crema will only work? doh.gif cause most of the video i watched their crema is so thick and nice drool.gif .

It's the same concept as green tea latte and hot chocolate drinks. Crema is not necessary for good art. A good, thick properly extracted espresso is however important as a good base for a good tasting drink. A low crema shot is usually watery and makes really tasteless latte/capp

good...if you don't have a proper and consistent espresso grinder and tamper, forget about depressurizing your filter for now...

but pressurised basket also can make a nice and thick crema too?

pressurized basket destroys good crema...creates fake crema...

good crema is velvety smooth...bad fake crema is big bubbly mess

for now don't worry about it...with fresh coffee, proper grind, dose and tamp, the crema will not be too bad. smile.gif

hahah, as a beginner i cant expect much, still in learning stage... just thought of trying my best to get a nice crema as i can~

Latte means 1 part espresso to 3~9 parts milk.

"Latte Art" is formed by crema and microfoam milk.

Your espresso looks too weak/watery...usual causes stale beans, bad grind, low dose, too much water.

Your milk looks too foamy...too much air. Microfoam looks like wall paint or whipping cream. You don't actually get any bubbles when you froth it well, and it stays that way until you finish the cup. The microfoam does not come together to form bubbles.

espresso seems more like a problem for me more cause i couldnt get a nice crema.. i jz got my lavazza qualita oro few days back, thought it will be ok, end up still disappointed... been try fine and coarse grind, both still gave out the same weak crema... any more tips or advice to improve the crema?
