Koryaiko Milesto Sahara EM-23 Pro review

The Koryaiko Milesto Sahara EM-23 Pro is the only genuinely commercial machine in this category: dual boilers, dual PID, a 15 bar Italian ULKA pump, a 58mm commercial group, and a 3.8L tank, at around ₱40,900. Be clear about what that means before you buy. At 21.8kg this is equipment for a business, not a kitchen appliance.

What does a dual boiler actually change?

Everything about serving more than one person. A single-boiler machine has to switch between brew temperature (around 93°C) and steam temperature (around 145°C), and waiting for it to move between them takes 30 to 60 seconds each way. Fine when you are making one flat white. Ruinous when six people are queuing.

Dual boilers hold both temperatures at once, so you pull a shot while the steam wand is already hot. That is the single feature separating a café machine from a home one, and it is why service counters pay for it.

The dual PID keeps each boiler at its set point rather than letting it drift, and PID is what makes shot fifty taste like shot one. Copper boilers hold heat more evenly than aluminium.

Why the 58mm group matters

58mm is the commercial standard, which means an 18g to 20g dose, and it means every tamper, basket, and bottomless portafilter on the market fits. Smaller 51mm machines cap you around 14g and leave you shopping in a thinner accessory market. If you plan to serve customers, buy 58mm.

The 3.8L tank is a volume feature: it means refilling between rushes rather than during them.

Is the Milesto Sahara EM-23 Pro sulit?

Around ₱40,900 as of August 20, 2026. As a home purchase, no, and we would not pretend otherwise. As business equipment the arithmetic is completely different: a small café pulling 30 drinks a day over three years puts roughly 32,000 drinks through it, which is about ₱1.25 a drink in machine cost. One sale covers a week of that. Commercial machines from Italian brands with the same dual-boiler layout start several times higher.

Note the shop, too. Koryaiko is the official Philippine distributor for this line, which matters when a 21.8kg machine needs service.

Who the Milesto Sahara EM-23 Pro suits

Buy this if you are opening or running a small coffee business and need to brew and steam at the same time. If you make two cups a morning at home, this is the wrong machine and the H10Plus does what you need for a third of the money.

If the Milesto Sahara EM-23 Pro is not right

For commercial-grade parts in a single-boiler body at half the price, the Gemilai 3006 is the sensible step down. For a serious home setup, the HiBREW H10Plus gives you 58mm and dual PID for around ₱15,000. See our best espresso and coffee makers roundup and the coffee maker buying guide.
