Since your coffee is over 98% water, it makes sense that the quality of the water will impact the taste. One of the subjects regularly bandied about in the home espresso world is if there is a significant impact on one’s shot if using a machine that has a separate brew boiler — especially if the machine isn’t pulling a lot of shots regularly and the water has a chance to sit for awhile in that boiler.
We have spoken with folks on both sides of the ‘divide’: Those that think the water goes stale in the brew boiler so that a heat exchange provides a cleaner, fresher taste and those that think the temperature control and performance differential you get from a double boiler outweighs any concerns of water flavor.
So we asked Gail to perform a practical test for us on the La Spaziale Mini Vivaldi: We dialed in our shot and then let the machine sit for a couple of days. Then we pulled shots with the water in the reservoir and boiler and shots with fresh water in the reservoir and a completely flushed brew boiler. Watch and find out the results.
One of the best things about investing in a higher-end semi-automatic espresso machine, such as the Rocket Giotto Premium Plus or Rocket Cellini Premium Plus, is the improved steaming functionality. Larger boilers and professional-grade steam wands make producing velvety microfoam the standard in your home or office — but you can always improve on a good thing, can’t you?
Check out the steam tip upgrade available for any of the Rocket Espresso machines including the Rocket Cellini Classic. This 4 tip set features different hole patterns that will improve the aeration of your milk while steaming, allowing you to easily make creamy steamed milk, every time. We love the ability to experiment above and beyond the factory-provided steam tip and think it’s an excellent accessory to your already excellent machine.
