Keurig K40 Elite Brewing System
  • We've owned this wonderful little machine for 6 years and we'd never go back to a regular coffee pot.
  • Its small size helps keep counter space in our little kitchen clear.
  • was the perfect solution for our small candle shop where we wanted to make coffee eacoco available to our customers, but didn't want to keep a pot on to get stale all day long.
  • I love the smaller size which is great for my small counter. I live alone so being able to brew one cup at a time is less wasteful than brewing a whole pot.
  • Sleek, eclectic, functional - all terms used to describe this gourmet home brewing system. Compact in any kitchen, the ease of its use matches its attractiveness
