Third-party reviews

What customers like about Sage The Bakery Boss SEM825

  • Powerful 1200W motor with 100% metal gears easily handles heavy tasks
  • Comes with two highly useful mixing bowls (4.7L glass and 3.8L stainless steel)
  • Double-sided scraper beater significantly reduces mixing time and cleanup
  • Integrated LCD timer helps monitor progress and prevents over-mixing
  • Helpful built-in LED bowl spotlight and lit speed guide reveal mixing progress
  • Smooth speed transitions without aggressive jolting
  • Sleek, robust, and premium die-cast metal design

What customers don't like about Sage The Bakery Boss SEM825

  • The 4.7L glass mixing bowl is quite heavy to lift and carry
  • Lacks an attachment hub for expansion accessories like food grinders or pasta rollers
  • The machine can shake noticeably when processing heavy doughs with the scraper beater
  • Expensive premium price tag compared to entry-level stand mixers
  • Kneading performance can sometimes struggle with flour on the outer sides of the bowl
  • The appliance has a large, heavy footprint that requires ample counter space

Verdict

The Sage The Bakery Boss SEM825 is a premium stand mixer featuring a powerful 1200W motor, heavy-duty 100% metal gears, and load-sensing technology that automatically adjusts power to maintain speed. Its primary characteristics include commercial-grade planetary mixing action, an integrated count-up/countdown LCD timer, 12 variable electronic speed settings with an intuitive text-labeled task indicator band, and an integrated under-head LED bowl light. Main advantages include the dual-bowl offering—comprising a 4.7-liter borosilicate glass bowl and a 3.8-liter stainless steel bowl—alongside a double-sided scraper beater that cuts mixing times by up to 60%. However, notable downsides include its heavy weight and bulky footprint, and the fact that the glass bowl and the wire whisk attachment are not dishwasher safe.
