Appartamento Seroes

I’ve had Rocket HX machines for the past 14 years and never had a problem making milk-based drinks or entertaining. I think double boilers are overkill but to each their own. As commented below, a $20 smart plug solves your preheating problems. Who says the water reservoir doesn’t come out? Is that a thing? Mine does. Plumbing in would be preferred but my space isn’t big enough in the kitchen so my machine is off to the side on a coffee cart. Happy coffeeing.

This is a very generous gift! Before getting into it, respectfully are you absolutely positive the couple is interested in espresso to this degree? These are endgame machines that would suit someone who is already an enthusiastic hobbyist, but not great for someone who just wants a quick coffee and isn't really interested in making it a hobby in itself. The other main thing I'd note is the grinder is often considered just as if not more important than the machine itself, and their grinder is not going to be able to do justice to any of these machines. It would probably be better to split the budget and allocate more money towards a high-quality grinder and then a slightly less expensive machine. For example you could get a Lagom P80 and Breville Dual Boiler for ~$3200 combined. A scale for weighing input/output is important at this level too and can run $100 - $300 depending on how nice you go, so it might be worth accounting for that, or the recipients might end up needing to buy it themselves. Accessories (nice stirring tools, funnels, tampers etc) can add up slightly as well. Regarding water, *some* brands of bottled water may be suitable although I'm not sure which ones - it would be important to look up the mineral content to make sure they're not prone to causing scale. Distilled water is NOT safe for espresso machines, it can cause corrosion in the boilers and isn't good for taste anyways. It is possible to add minerals to distilled water to make a perfectly scale-free water with suitable taste (look up "Pavlis water") but again not sure if the couple is really interested to that degree. Of the machines you listed, the Appartamento is inferior to others and is not in the same tier. I don't have experience with the others but would note that a Lelit Bianca V3 is personally my upgrade wishlist machine for now. I have a Breville Dual Boiler today, which is an exceptional machine in pretty much every regard and why I noted it above, it's just not a 20-year lifespan machine in terms of build quality.

I had the exact same dilemma 3 months ago (single boiler or hx) and went for the heat exchanger (Rocket Appartamento in my case though) and couldn’t be more glad I did.

The steam wand is crazy powerful, I need to purge it for max a second and all the water is out

For $600 it’s unbeatable. Used one for years. Have a rocket apartamento with Rancilio grinder combo now and the setup is 6x the price and the coffee isn’t 6 times better. I still miss my dear friend “coffeebot” some days… nothing wrong with barista express you can get a better portafilter if you really want. But the stock machine and components make a damn good espresso if you know what you’re doing and have quality beans 👍

Where do you live? Proximity to somewhere to get the machine serviced may be something to factor in here (can vouch for Monteriva in Stockholm), since any non-basic maintenance (i.e. beyond replacing grouphead gasket) may require technicians… Unfortunately we have a somewhat limited network of service technicians - I went with Rocket machines (starting with an Appartamento which is still going strong in a summer cabin)!

would definitly look into young used machines, so many people get into this hobby and then stop because they think too much work involved. I'd look into a Rocket, ECM, Profitec, lelit etc... Minimum Heat exchanger boiler. (I have a Rocket with HX boiler, make only 4/5 cappucino's a day without any problem) and a decent grinder.

can't recommend the Rocket Appartamento enough, best of the marzocco without the cost
