<p>The problem (for you) with espresso is that the amount of coffee brewed per serving is small and it tends to lose heat faster than, let's say, a mug of filter-brew coffee from a jar that has been sitting on a hot plate.</p>
<p>I found some interesting information on:
<a href="https://www.1stincoffee.com/art-of-making-espresso" rel="nofollow noreferrer">https://www.1stincoffee.com/art-of-making-espresso</a></p>
<blockquote>
<p>The brewing temperature is the temperature of the water at the point
where it comes into contact with the ground coffee. This temperature
is controlled by the thermostat of the espresso machine and should be
88C to 91C. The temperature of the brew in your cup will be between 71
and 74C. The heat loss occurs in the brew group, the air, and the cup.
This is the ideal temperature for espresso in order to feel hot
without scalding. To keep the beverage temperature from being too low,
you should preheat the brew group and the cup. The easiest and most
reliable way to heat the brew group and the cup is to run the cycle
once with water only. This will heat the brew group, including the
portafilter, and the cup simultaneously. A cup warmer will also help
keep cups warm when you are making multiple espresso beverages.</p>

<p>From my experience, excessively hot espressos ( &gt; 80C ) like the ones served in restaurants in my country tend to yield a horrible burnt taste and are a telltale of a bad barista or a malfunctioning machine</p>

<p>Thanks @Patterson for taking the time to answer our questions.</p>
<p>The short answer to your question is that you will not find that feature in any commercial espresso machine. The reason for this is simply that espresso is best brewed using water with a temperature of around 90° C, so thermostats in those machines are typically set to around 92°.</p>
<p>However! And this is a big however. Several things steal heat away from the water before the water ever touches your cup. Those extra few degrees on the thermostat are there to help the coffee stay about 90° when it hits the coffee, but after it hits the coffee, the water hits the (metal) brew group, brew head, and shower screen. Slurrrppp. There goes that heat. Your coffee will be closer to 80° C by the time it hits your cup.</p>
<p>Then, the cup... Oy. I know you said your brewer had a heating tray to heat your cups, but those trays don't actually do much. If your cups are glass, stoneware, or porcelain, you're probably losing another 10° or more to the cup--even counting the warming you're doing. This is because these materials are decent insulators. That hot plate heats the top of the cup where you drink (assuming you place the cup upside down), but the heat doesn't make it down into the part of the cup the liquid touches. You can probably tell this by simply picking up said cup. A cup hot enough to protect the heat in your drink would be quite a shock to grab because it would be <em>hot</em> and will actually burn you quite badly if you hold onto it for more than a second or so.</p>
<p>So yeah. For machine to serve piping hot coffee, it would have to brew first, then either boil the brew (which would create a very different drink from espresso) or add boiling water (which makes an Americano and not an espresso). You won't find a machine that does the former, and a machine that does the latter is not an espresso machine.</p>
<p>That said, espresso based coffee drinks aren't typically served piping hot. Like I said before, ~90° C is the target water temperature for brewing, and milk for lattes/cappuccinos/whatever shouldn't go over ~70° C because high heat will mess with the proteins and sugar in the milk. Consider giving &quot;warm&quot; espresso a try because that's generally the tastiest way to get it.</p>

<p>I have just returned the De'Longhi Eletta Cappuccino ECAM44.660.B Bean to Cup Coffee Machine. Not because it didn't make nice coffee, but because the coffee was luke warm within seconds of drinking. Basically, the coffee was never hot. I followed the instructions to make it hot i.e. Place coffee cup on hot metal tray before dispensing the coffee, heating the coffee cup with hot water before pouring the coffee, plus many other suggestions.</p>
<p>I have googled for hot bean to cup coffee machine, and the general impression is that I will never be able to purchase a machine that will produce really hot coffee.</p>
<p>Can someone let me know if it is indeed possible to purchase a hot bean to cup coffee machine?</p>

Hi @Patterson, welcome to Coffee SE! Can I kindly ask if you've done any triaging of the problem? I see you've already tried a few ideas for solutions, but did you ever check to see, for example, if the coffee right out of the machine was hot? And how hot do you expect coffee to be?

I have a Delonghi Magnifica ECAM-3500 here. Never had any issue with the temperature of the coffee it brews, i always warm my cups with a bit of boiling water (even if they were left in the hot plate above the machine) to improve the taste of the coffee and to make the crema last longer. Serving on a cold cup will suck away heat from the coffee and bring down the temperature of the beverage by 10C or more.

Did boiling water come out of the water sprout ?

Hi, all thanks for welcoming me to the group. So, I must admit, the coffee right out of the machine is hot, but not as hot as coffee from a kettle. As for how hot I would like the coffee to be? I would like it piping hot. 
The general impression I'm getting is that I'll never be able to find a bean to cup coffee machine that can provide really hot coffee. If that is the case, then so-be-it. But I just would like to know if its possible?

How hot is not so hot? If you filled a plastic or a paper cup (little heat lost to the cup), what temperature is the brew just after the machine finishes? I don't think you'll get much past 90 degrees C there but if it's a lot lower then there's probably room for improvement.

@Patterson Can you please give a temperature you consider piping hot? Are you looking for near-boiling?

@RMac, and others, sorry for the delayed response. I am looking for near boiling hot .. is that an unrealistic expectation?

From my experience, excessively hot espressos ( > 80C ) like the ones served in restaurants in my country tend to yield a horrible burnt taste and are a telltale of a bad barista or a malfunctioning machine
