Testing: Coffee Ground Attrition & Water Content in Frothed Milk

We had a few viewer requests lately around the weight of things, so we produced two videos covering the following questions: How much coffee is left in the grinder after grinding? How much water is injected into milk when frothing?

In this first video, we weighed out 20 grams of whole beans and then ground them in several different grinders, weighing the grounds afterward to see if any was retained in the grinder.

In the second video, we weighed out 200ml of milk (in most cases — the exception being the stand alone frothers), frothed them to the same temperature on several different machines and then weighed them afterward to see how much water was injected into the frothed milk.

What’s this White Stuff on my Rancilio Silvia?

There are a couple of questions that we get all the time about the Rancilio Silvia:

  1. Why does my machine have two water tubes? The manual only shows one.
  2. Why is my machine white? I ordered a stainless steel version.

We briefly discuss the answer to question one in this video, but we also covered it here awhile ago. For question two, Gail explains this great mystery in the video below.

Backflushing with Cafiza Tablets

We have a wide array of cleaning products available — from descaler to milk frothing cleaner to backflushing detergent — and, admittedly, we sometimes get a little stuck in our ways. Machines with a three-way brew pressure release/solenoid valve (such as the Rancilio Silvia, La Spaziale machines, many of the Ascaso machines and any of the machines with an E61 brew head), require regular backflushing in order to keep that system in tip top shape.

Heretofore we have always recommended powdered backflush detergent — Cafiza or Joe Glo — but when we were meeting with Urnex a couple of weeks ago, they mentioned using the Cafiza tablets for backflushing. And it blew our minds.

Yeah, it doesn’t take much, does it?

If you want to be precise about the quantity of detergent you’re using in your backflushing and cleaning your gear, these tablets are the exact amount you need. Place one tablet in your backflush basket and follow your process as normal; one tablet in a couple cups of hot water is perfect for soaking baskets, portafilters and any other gear you may have that comes into contact with coffee oils and needs a good scrub down.

So what we previously attributed solely to superautomatic brew group cleanliness is cross functional and a great way to easily backflush your equipment without concern of using too much/too little detergent.

Internal Espresso Machine Parts Now Available!

If you have been on the long lost search for the perfect O-ring, gasket, steam manifold or thermostat for your DIY espresso machine rebuild project, you’re going to be pretty excited to learn about the new parts section of our site. Admit it, you are.

We’re now offering tons of internal parts for espresso machines, easily located via exploded machine diagrams. Right now we’ve built out the parts for several of Saeco’s machines and we’ll be expanding those as well as adding other manufacturers in the future — such as Ascaso, Quick Mill, Rancilio, Rocket Espresso and Solis.

If you’re technically savvy enough to diagnose your machine, understand which parts it requires for repair and then install said parts without injuring a) yourself and/or b) the family pet, this is for you. However, if you think you need information on what’s wrong, what to buy and how to install, let us tell you like a friend: We have an excellent repair center that will more than meet your needs.

Espresso Machine Storage Tips

Leaving your machine alone for the winter? Need to store it or move it (by hand) to a new location? Gail gives us some tips on what you should do to prepare your machine so you limit the possibility of damage.

Why Does my Rancilio Silvia Have 2 Water Intake Tubes?

A few times per week, a new Rancilio Silvia owner calls in with this question — what the heck is that 2nd tube for? The machine diagram in the user manual hasn’t been updated by Rancilio to show this tube or describe what it’s for, so we recorded this for posterity. Gail shows us the tubes and talks about their functions.

Rancilio Silvia & La Marzocco Filter Basket Face Off

One of the most loved home espresso machines on the market is the Rancilio Silvia, which offers a great value in terms of price and performance. And, as with most things that are well-loved, this machine gets a ton of attention, tweaks and upgrade suggestions as folks quest for the best shot possible. One of the suggested changes is to swap out the stock filter basket that comes with the Silvia for one that is manufactured by La Marzocco — not only does the latter basket fit more coffee volume, it also has straight sides so you can tamp it more firmly.

We picked up one of these baskets and Gail did a toe-to-toe comparison of how each basket performs to see if there really is a noticeable difference. Enjoy!

Field Trip: Uesugi USA – Recycling Center

Where do espresso machines and coffee makers go to die? Not in the landfill, if we can help it! At Seattle Coffee Gear, we launched a recycling program last year in an effort to keep as many fully assembled machines from landing in the trash. Many of these are pretty complex — they have circuit boards, electrical wiring and miscellaneous metals that are best kept out of our ground water supply.

Our partner in this venture is Uesugi USA, a Japanese company that (as luck would have it) have a US presence here in the Seattle-area. We pulled Henry into the mix and headed out to their facility to talk about what they do and see how they take these machines apart, break them down to their components and funnel them back into the commodity supply chain as cleanly as possible.

Which is Better: 2 Hole or 4 Hole Steam Tip?

We often get asked whether or not a 4 hole steam tip is worth the upgrade on a machine like the Rocket Giotto Evoluzione. You definitely need to have more power to back up a multiple hole tip — as was seen on the first iteration of the Rancilio Silvia V3, the boiler size did not match well with the 3 hole tip and folks got very lackluster results. So it’s important to match the right tip to the right machine.

Gail shows us how each performs side by side and gives her assessment on their benefits/drawbacks.
