If your coffee tastes watery, sour, or weak, it's likely because the coffee grounds are too coarse. This means the water is passing through the grounds too quickly, not extracting enough flavor. To fix this, you should grind your coffee finer.But I already set to the 2nd last fine setting. OK I'll try setting to the last setting the next time when making an expresso and see how
Different beans will need different grind setting, best is to test or feel the coffee powder with new brand of beansThis machine need to experiment to find sweet spot … too fine the ground coffee scatter all over the place instead of going into the brewgroup … too coarse you get wet puck.
Unfortunately it seems different brand different roast also got different sweet spot … Starbucks beans I set to finest I don’t have any problems, this batch of Zero beans I never change the settings but I open up the side door see inside, my ground coffee all over the place.

Here's why a coarse grind leads to a weak brew:
Reduced Flavor Extraction:
Coarse grounds have less surface area for water to interact with, resulting in less flavor extraction.
Faster Flow Rate:
Water moves through coarse grounds quickly, not allowing for proper extraction of the coffee's flavors.
Under-Extraction:
The coffee is not fully extracted, leading to a weak, sour, and watery taste.
How to fix it:
Adjust Grind Size: Use a burr grinder to achieve a finer, more uniform grind.
Try Different Brewing Methods: Some brewing methods (like French press) are designed for coarser grinds, while others (like espresso) require finer grinds.

Usually such burr grinders aren't really that fine, I've used breville built in grinder, delonghi espresso grinder but their finest really world apart from those 64mm flat burr grindersI have set to the 2nd last fine setting using the built-in grinder. My SMEG coffee machine is basically an expresso machine
I did the jump from Nespresso to 1 yr plus ago, getting better quality espresso and having more fun learning about grinders and etc but pocket also burn a holeall these recent coffee machine threads make me itchy to get a breville oracle jet...
currently using a nespresso lattissima touch... hai... the urge...![]()

All in one are not designed to run too fine, it has no exhaust for over pressureI'll try to use the finest setting the next time when I make an expresso. I believe my medium roast acid-free beans affects the flavor
you guys driving me towards the dark..er side....Your Nespresso only gives you 5g of coffee, $1.
I make one using double shot use 18g. 40c.
Very easy one, maid my 90 yo, 9 yo also can do it. And I'm talking about those professional ones, not all in one.![]()
It's not sour because you under extract.

Look at that shot, it looks like almost 80ml.
The astringent from the overextraction bury everything. It should still taste better than a Nespresso though.
For double, I at max 50ml, normally 30 to 40ml depending on roast level.
Better switch.you guys driving me towards the dark..er side....
It's definitely not the beans, only when I got a 64mm flat burr then I found out that the size of the grinding can affect a lot in the taste of the same batch of coffee beans, it's really a world of difference. Previously when I was just using normal grinders set to the finest, coffee was with creama, slightly sour and bitter typical dark roast taste. Aft using better grinder, same beans now got fruity taste and almost not sour and the bitter got more dimensionI'll try to use the finest setting the next time when I make an expresso.

I find it hard to believe, I have a similar espresso cup. Unless you poured the espresso into water.No. I measure and its 30ml. The cup is small that's why you see it looks like 80ml

Oh yah... Forgotten you got the semi auto, but for $1000 I rather get a brevilleThe SMEG machine cannot use ground only whole beans
