Hi @joesimpson4655, yes I did. I dialed in both espressos to roughly a 2-2,2:1 ratio in 25 to 30 seconds having grind size as the variable.

@@simmesreviewsmay I ask, I use the Fiorenzato F64E grinder, Which size I should use for Robusta ? Thank

@@KhoaNguyendz13 I can’t tell you an exact number. However I would always start with the recommended recipe of the roaster or if not available the standard recipe. So fix all variables you want to achieve, except grind size. E.g. standard recipe: take 18g of ground beans and aim to get 36g of espresso in 25 seconds. Now if the 36 grams came out to quickly, say in 20 seconds, you need to set your grinder to a finer setting. If it took to long, than set your grinder coarser. This should lead to a tasty espresso. From there you can adjust to your liking by aiming on a different ratio (e. 18g to 42g for a more balanced but watery espresso or the other way round for a more textured but probably bitter shot. Hope this helps

Hi @lailahossman, I would say ratio depends on personal preference. It can be the same but doesn’t have to. I would not generally say, that there is a rule to use a different ratio just because it is Arabica or Robusta.

To be honest I am currently using the 2 hole tip again. I have my steam boiler set on 1.5-1.6 bar. The 2 hole tip is more forgiving, as you have more time. I still love the 4 hole tip for its speed, but it needs you to be more present at what you do

It really depends on the roast level, I guess. Some feel this acidic notes are fruity. It seems to be trends, at times darker roast are hip than again lighter roast become more popular. Is there any bean you currently enjoy?

Thanks for your comment! I promise to continue to make videos… it just a lot going on right now. I feel the silent green is an improvement. But more so the upgrade of the Xenia to a Dualboiler system with the ability to regulate the pump. Turns out you can reach the needed pressure while running the pump at 70 to 80%… which in itself makes the machine more quiet

Thanks for the vid! You’ve convinced me that the ever so slight drop in noise level is not worth the $20 or whatever needed to purchase, and then the labor necessary to install, the Silent Green pump.

Hey there! as Robusta has a way higher caffein content, this may be why Arabica is the better choice for you.

Your welcome 🤗

@huhDisabo that is very common I think in many places. The reason is as mentioned by you the crema which many enjoy to see and also that robusta is a bit less expensive than arabica, so you can bring your costs per shot down. I also enjoy blends from time to time. I feel the combination of arabica and robusta also leads to a more diverse taste profile.

Sorry für die späte Antwort. War im Krankenhaus, aber jetzt ist wieder alles gut 😅. Meine Schwester hat eine Zeit lang in Krefeld gelebt. Sie ist ein totaler Entdecker-Typ… Wir haben schon mehrere Kaffees probiert und die Qualität ist immer sehr gut gewesen (nicht immer mein Geschmack, aber das ist ja normal…). Probieren lohnt sich 😄 Ich fand den Classico gut und der Verona klingt mir nicht schlecht… bin aber nicht sicher ob ich den Verona schon probiert habe.

Hey Wake Awaken! You are right. Also variety, and roast level will influence the amount of crema. Now the crema is very bitter; depending on the coffee I do like to have this bitter taste… some don’t like it to the point of even removing it with a spoon.

Thank you very much!

Honestly I am struggling to get enough creativity… it seems after work, I don’t have the motivation to do any videos… but after some important meetings in April, I promise to go on with new videos… Is there anything you would like to see a video on? Was thinking about a series on basic coffee recipes.

Thank you for your comment! Much appreciate it

Let’s try that… I just received a totally new type of temper. It works with a gel pad instead of the steel plate. Also I have used a screen puck for quite some time. So maybe I should do part 2 of this video

Hallo Amir, das habe ich vom Hersteller. Er hat mir gesagt auf was die Maschine eingestellt wurde und wie sich die Temperatur zu Druckanpassungen verhält. Jede Xenia wird vor der Auslieferung genau getestet und eingestellt. Diese Infos kann man dann dort erfragen.

Thank you!

Das ist für mich wirklich der größte Vorteil dabei. Zumal die Eureka Siebträger-Halterung nicht so die beste Lösung ist…

Ευχάριστο 😊

👍 Thanks a lot

That’s a good question…. I am not an expert, but I think that extraction level is at around 20%. So I think a double shot with 18g of espresso in your example should have around 18g *4% *20% = 144mg of caffeine. However a more realistic caffeine level is around 1.2 to 2.2% This link might answer your question coffeebros.com/blog/how-much-caffeine-is-in-espresso-and-coffee-hint-its-not-what-you-think/ They say a double shot has more like 80-100 mg of caffeine… depending on the bean. Unfortunately they don’t show the calculation. But with the 2.2% caffeine level in the bean it would be 18g * 2.2% * 20% = 80mg Hope this helps!

That’s great! Good to hear the video helped you. Enjoy you Cappucinos 😀👍

Thank you Michael! I did had quite some struggles in the last months, so I neglected the channel. However latest next Sunday there will be a video… I was working on a video about single dosing, but maybe your idea is better and I should work on the promised cream video! Thanks again. Your comment is a real motivation 😀

@@simmesreviews yes please! Do you have an opinion on stirring the crema before drinking?

Hey Michael! Crema video just got uploaded: th-cam.com/video/WR0NhQo6aZQ/w-d-xo.html Your last question is answered in the video ;-) Thanks again for the support. Really appreciate it!

@@simmesreviews great video! I don't know how I missed this video until now! I stir my espresso fyi 😜

I would love to know the answers to these questions as well 😁

Hi there! Sorry for the late reply. So the Xenia is not a steaming monster. However I am able to pull a double shot and steam milk for 2 Cappuccino at the same time. Also if I am not mistaken Xenia is currently working on introducing a slightly larger boiler as an option - so in case you are worried, go for the larger boiler.

Thanks @simme! I'm patiently waiting them to release their dual boiler PID model 😎 Other than that how do you like the machine overall?

Thank you! I really enjoy my daily dose of coffee ☺️

Interesting topic. I am going to explore that and come back to you

Yes and no! I generally always start with the dose fix at 18g in and try to get the desired ratio by varying the grind size

Robusta overextracts quicker so you make the grind size larger, thus making it faster

That is true, however I prefer leaving the sugar out with any espresso... but the taste profile is very different. There was a robusta in the tasting Hofmann did, and even blind it was very clear how it differs from the arabica coffees. There are times when I like one more than the other.

Hey! Sorry I was away for a couple of weeks... how is the Xenia? Did it arrive?

Thank you!

That is so true. I do found myself first drinking more Robusta and now moving towards Arabica. It seems to be changing over time, but this is the beauty of having a portafilter machine. It opens up the whole world of espresso and never gets boring :-)

Only now found arabica have way less crema than robusta :( ah. Well i bought 100% arabica crema yesterday. But wanted mix of arabica and robusta from lavazza but i said nah robusta is just too strong and bitter and want good cremy coffee with not much bitter . But i was mistaken its look next time i will try that mix one

Thank you! It was fun to make... this will be a nice series for me to learn more about coffee and drawing...

Hi v0gel mann! I am very happy with the machine. Planing on a proper review video shortly. The machine is not perfect, but as you will see the beauty is not only in the machine but in the power of having a capable small manufacturer backing the machine :-)

Thank you! I was not planing on it, but why not :-) maybe I will do a full review in the near future

Guter Tipp! Habe schon die nächste Packung auf dem Weg... werde das auf jeden Fall probieren und mich nochmal melden :-)

For me design was highly important. I do like the balance between classic portafilter style and modern coffee machine. For the more modern look you could go with a bolder color, for the more classic look you could choose the stainless steel or brushed steel look.

Very helpful and great video.I have an ECM Synchronika which came with a 2-hole tip, but since I do a lot of small 35CL pitcher (4oz milk) single cappuccino I think the 2-hole is perfect. I was considering upgrading but I think the 2-hole is the best fit. Thank you!

@@postbeam8200 thank you! Having used both tips for a while I see your point and totally agree. The 4-hole is too much for smaller pitchers. I even found myself using the 2-hole with a 50cl pitcher since it gives you more time (which I do need in the mornings...)

Ok! I am thinking about making a espresso tasting series. Each 1-2 weeks another espresso :-)

Danke :-) Eine gute Siebträgermaschine kann ich nur empfehlen... ist wirklich jeden Tag etwas auf das man sich freut, wenn auch mit deutlich mehr Aufwand als bei Vollautomaten oder Kapselmaschinen. Aber das Zubereiten ist halt auch ein Hobby.

mit hohem robusta-anteil?
