Sage Dual Boiler Review: A Latte Art Finalist’s Verdict
The Sage Dual Boiler heats quickly and can pull shots while steaming milk, because it has a separate boiler for each. Two-time UK Latte Art Championship finalist Ben Lewis rates its steam wand among the best he’s used at home, and its programmable temperature and shot volume make results consistent.
We asked Ben Lewis (@barista_benji) — at the time head of coffee at The Winchester Orangery — to put the Sage Dual Boiler and the Sage Smart Grinder Pro through their paces. His video and review are below, followed by what to stock alongside the machine. Review recorded in 2021.
What’s the Sage Dual Boiler like to use?
Heat-up and workflow
“Because it has two separate boilers, the Sage Dual Boiler heats up quickly, so you’re not waiting a long time for your first coffee of the day. It also means you can pull shots and steam milk at the same time, which gives you speed and lets you make several coffees quickly. That’s particularly good if you’re moving from a café to being a home barista.”
The steam wand
“The steam wand quality is phenomenal and one of the best I’ve used at home. It lets me make good-quality microfoam for great-tasting coffee, and for latte art. I can easily replicate competition-level latte art, so I can practise at home for competitions.”
Temperature and shot control
“You can change the temperature easily by adjusting a few simple settings. You can also program the amount of water for each shot, so you get consistent shots every single time.”
The Smart Grinder Pro
“The Sage Smart Grinder Pro lets you pre-program the timer and grind size, so you get a good-quality grind and the exact same amount of coffee each time.”
Design
“It’s a beautiful machine. It looks really good in my set-up and will fit into pretty much any home.”
Who should you sell the Dual Boiler to?
- Customers who make several milk drinks at once — families, keen hosts.
- Home baristas who want control over temperature and shot volume.
- Ex-baristas who miss the workflow of a café machine.
- Customers who want a smaller, all-in-one machine may suit the Sage Barista Pro, which has a built-in grinder.
