What we like about Gaggia RI8427/11 GranGaggia Prestige

  • Compact and durable stainless steel design fits well in small kitchens
  • Produces high-quality espresso with good crema thanks to 15-bar pressure
  • Features a pressurized portafilter that makes it easier to achieve good shots, even for beginners
  • Supports both ground coffee and ESE (Easy Serving Espresso) pods
  • Attractive, premium appearance compared to similar plastic models

What we don't like about Gaggia RI8427/11 GranGaggia Prestige

  • The milk frother can sometimes produce hot water instead of steam, leading to watery milk
  • Lightweight construction means the machine may move slightly during operation
  • Requires a learning curve to get the best coffee quality initially
  • Some users reported issues with the milk spout fitting properly

Verdict

The Gaggia RI8427/11 GranGaggia Prestige is a compact manual espresso machine featuring a full stainless steel bodywork, a 1-litre removable water tank, a 15-bar pump, and a 950W boiler system. It accommodates both ground coffee and ESE pods, offering simultaneously dual-cup brewing and an integrated ambient cup warmer on top. Key advantages include its patented "Crema Perfetta" pressurised filter holder for effortless crema extraction, a classic stainless steel Pannarello steam wand for milk frothing, and a robust, space-saving design. However, it has some drawbacks, such as a low cup clearance of only 75mm that prevents fitting standard larger mugs, a spring-assisted portafilter handle that makes double-cup spout alignment tricky, and the lack of an automatic steam-venting system, requiring users to manually cool down the boiler between steaming and brewing to prevent burning the coffee.
