Did you know that changing the water pressure applied to the bed of coffee when making espresso can dramatically alter the taste? In this video Luke is using the La Marzocco GS3 and varying the pressure profiles to see how it changes the flavor of coffee. He extracts coffee using 3 bar, 6 bar and 9 bar pressure on the GS3 and analyses how it tastes in both milk and espresso style coffee.
In his experiment he discovers some interesting findings in his results.

I have watched this several times and enjoy it and learn something each time. I have the same machine and have had it for close to two years. I have been focusing on grinding finer and extending the pre-infusion to about 15 seconds and then move slowly from 3 to 9 bar. I really like the depth of flavor and the mouthfeel with milk based drinks. Shots are so predictable and controllable with the GS3MP. I am going to try more straight 9 bar shots to see how they compare. Great presentation and valuable information. Thank you for sharing.

Thank you. The gs3 is great for a playing with the experience, a full 9 bar will give a typical LAMarzocco taste, it’s great sweetness, full body and it will increase the acidity a bit more over the lower pressure extractions this helps cut through the milk

Great video with some unexpected results - which proves there is nothing sacred about a nine bar pump setting - it depends..... on what you like, the coffee type and it seems some experimentation is worthwhile. I never expected the 3 bar result would be acceptable! Also nice demo of the much respected GS3 with great shots being pulled even at low pressure!👍

I have a Lelit Bianca and will be trying this simple way of getting different tastes and textures. Thanks for making it simple, since you can really make this complicated with changing grind dose etc. I find you can over complicate this very easy. Thumbs up to video. AWESOME

Thanks for making these great videos. I am like many others that picked up this hobby during the lockdown. Being a newbie, I have learned a lot from your channel and continue to enjoy watching you explain things. My setup is a double boiler (Izzo Alex Duetto IV) and a Niche Zero grinder. Maybe one day I will get into pressure/flow profiling.

Great video guys. Now that you started making videos on this profiling topic, I would like to ask you to make videos about flow profiling. I understand they have stable presure but the flow changes whereas with presure profiling as you don't open the valve completely, you affect both pressure and flow. I leave it as an idea, thanks!

@ArtistiCoffeeRoasters 3 жыл бұрын

Thanks. Flow is in on the list for sure. Stay tuned

@animaze8043 2 жыл бұрын

Flow is determined from the pressure vs resistance in the system. Higher pressure, more flow. Its not two completely seperate ways of extracting, its controlling pressure vs controlling the resistance via a constriction (valve etc).

@frankmeyer1865 11 ай бұрын

great introduktion, will it work with a not plumbed gs 3 MP or is it diffrent because of reduced conduct pressure?

@ArtistiCoffeeRoasters 11 ай бұрын

It’s still works with pressure profiling, the pressure just has to build up from 0-3 by the pump as mains is usually 3 bar. You can’t notice it either way. Cheers luke

Can you try with 12 bar also?

@aryehh7128 2 жыл бұрын

My local roaster gave me a shot at 15 bars. That's his go-to choice. Also La Marzzocco I hoped you'd go at least up to 12, even 15. I wish you might have edited out more of the view of you recording on the paper. Also, I understood a lot of people start at one pressure, then ease up or increase over the course of the shot. On purpose.

@ArtistiCoffeeRoasters 2 жыл бұрын

12 and 15 bar is really a lot of pressure, what equipment was that?

@aryehh7128 2 жыл бұрын

@@ArtistiCoffeeRoasters Some handmade La Marzocco machine, similar in width to yours. He likes that he produces a huge crema with it. The crema really makes up about 80% of the height of the double shot. Just a hint of slow sourness. The way a more traditional espresso has that good slight bitter bite at back of throat, but only a couple of seconds after taking the sip. Next time I'm there I'll try to find out the model name/number. But he implied it was a custom build, last time.

@Julieesnake Жыл бұрын

Hey man, Thanks for a informative video. Im wondering if you consider the natural difference within the same bag of coffee and how that affects the flavor you get from the extraction. How many shots did you do pr pressure profile?

@ArtistiCoffeeRoasters Жыл бұрын

We try avoid the bag differences by pre weighing into small pots, buying a smaller amount. But yes a bag ages like bread

You can do either, I have left all my machines on for years. My gs3 is plumbed and has been on for 2 years. If you want to save power put it in standby mode. If your not worried about power but want to keep the inside healthy leave it on

I’ll look into it, the gs3 just came out with the IOT, so wifi and Bluetooth connection, new installed steam wand. So that’s a out 3 months old.
