Espresso machines often list 15 – 17 BAR pumps in their technical specifications, but the general rule of thumb for most espresso extraction is for 9 BARs of pressure. In this video, Gail talks to us about this pressure differential, what you’re looking for and talks a bit about the new world of pressure profiling in commercial/professional espresso.
Always on the look-out to expand the vast array of espresso machines we have available, we just added the Breville series to our products over at Seattle Coffee Gear. As we’ve begun testing them, we’re starting to dig the 820XL — for a machine under $500, it’s got some great features.
First off, the die-cast, stainless steel casing is really gorgeous, with smooth lines and incredibly sturdy and durable finish. It also has programmable buttons, so you can easily reproduce your espresso shot every time, without having to worry about watching it to turn it off. Finally, it has a unique boiler design that results in a bit better temperature regulation than you might find on other single boilers in this class.
On the downside, it only comes with a pressurized portafilter, so you’ll have less control over your shot and it will be infusing the espresso with air — not producing a traditional crema. It doesn’t have a three-way release valve, so you end up with a watery puck, and the portafilter is stainless steel so suffers from some inconsistency in temperature regulation (unlike its chrome-plated brass brethren).
The September issue of Seattle Coffee Gear’s monthly newsletter has hit the bricks! In this month’s issue, we have a delicious Buttercream Cappuccino recipe, a directory of our most recent videos, some tips on using oily beans in your superautomatic and a few new product features.

When Rancilio was reworking the new Silvia, which was released in May, they tested it with a three-hole steam tip. It seemed to work just fine in their European testing labs, but when it hit the market in the US, they got nothing but grief. Ostensibly the difference in using a machine on 220V as opposed to 110V, the tip just didn’t offer a big improvement — the power and the boiler size simply couldn’t support the increase in steam expression and the resulting milk frothing was sub par.
Since the first iteration of the V3, they have released a new round of machines that comes standard with a single-hole steam tip. The steam wand is still the awesome, 360 degree articulating wand that we have grown to love on the V3, but with a single hole in the steam tip instead of three holes — which has vastly improved the steaming performance. If you’ve got the first generation of the Silvia V3 and would like to see how a one-hole tip performs, you can pick one up for just $9.95.
