Hi, I'm hoping a member of staff could clarify something for me. De'longhi have informed me that ALL their bean to cup machines should double the dosage of coffee beans when you select the two cup option. What are your thought on this? I have done some experimenting with my Prima Donna S and it definitely seems to up the dosage of beans, although not quite double it. In your video review of the ECAM 23.450 (at approx 01:28) the girls state that the two cup button simply doubles the amount of water but does not up the dosage of coffee beans.
Phill G on Jan 3, 2014
Best Answer: This is actually something that has puzzled us, too! I was recently speaking with my technicians about this and yes, pressing that button does increase the amount of grounds the machine uses, but it doesn't seem to be a true double of the amount of grounds to us either. I tried measuring the amount of grounds for the single and double cup buttons and wasn't able to find consistent enough results to say yes or no to your question, unfortunately. It is always best to rely on the manufacturer to provide most accurate information about their machines, and I am sorry I am not able to offer you better clarification on this! Hopefully regardless you are happy with your PrimaDonna!

Does this make a cup of regular drip coffee?
betty m on Oct 17, 2016
Best Answer: Nope! Machines with a coffee feature are hard to come by, I'd recommend the Delonghi Eletta ( which does have a special drip coffee option.

Best Coffee Maker EverReview by Mulvy
I thought I knew coffee with my built in counter coffee maker that looked so cool. The Prima Donna has taken my coffee schooling and knowledge to levels I never even imagined existed. My wife and I traveled Europe this fall for three weeks and fell in love with the coffee. I found a coffee supply shop in Paris that sold espresso machines, but it was too expensive to ship back home. So returning to the Northwest I did some research and found Seattle Coffee Gear.
I went to the Bellevue store and met Greg. He was very helpful and listened to me as to what I was trying to replicate from Europe. I originally was looking to buy a machine that i would have to grind beans, tamp and pull the shot. He informed me that there is a learning curve to this process but I could learn it. But I knew my wife and daughters would not be as interested as I. So I asked Greg to direct me to a machine that the whole family could use with little effort, but one that also gave me the European espresso with the lovely cream a on top. He directed me to the Super autos with many choices. I choose DeLonghi because they had some of the highest ratings. And Seattle Coffee Gear is a service provider for them. I choose the PrimaDonna S De Luxe because it gave me the most consistent pulled shots. The milk feature for all milk drinks was super easy for my family. With one touch of a button, you have a professionally made coffee drink. It has a very large water container and I love the water filter feature. I love that I can program the MY COFFEE feature to exactly how I want my coffee every day. I too love that I can decide how strong I want my taste to be and what size for what time of day I'm drinking coffee. This is my first super auto coffee device and I LOVE IT! I see it being a very fun part of our family for years to come. It was not the cheapest home super auto machine, but DeLonghi makes a premium product I'm convinced and would buy it again.

I love this MachineReview by Mary
I didn't buy my machine through Seattle Coffee Gear. If I'd known your company existed at the time, I would have. Your store seems to be very fun to visit. Unfortunately I live too far to have the advantage of visiting Seattle Coffee Gear. live on the opposite coast. I have enjoyed the employee's sense of humor on You Tube. I love the expanse of knowledge and experience your employees. They seem to be good people! Now, my comments about the DeLonghi PrimaDonna S De Lux. I love this machine. When I compare it to my last machine, this machine delivers a rich espresso and coffee flavor expected with a high quality machine. If I desire a cup of "hot" coffee it doesn't let me down. I love the push of a button drink menu and I am still able to customize what comes out. I would have purchased its big sister with all of its bells and whistles but since it's only my husband and I, all the programming on that machine would have been a waste. I am delighted with this purchase. This is a beautiful machine. (Posted on 6/26/2014)
