For classic espresso extraction, it’s difficult to beat the clean lines and elegant design of La Pavoni’s series of lever espresso machines. We sell a few different variations, so asked Gail to take us through a feature and functionality comparison of them.
When is it time to say when? We’re often asked where the portafilter should be in respect to the machine — at a 90 degree angle? 45 degree? A little over to the right? Every machine will be a little bit different and the key is to make sure that it feels snug. Additionally, you’ll find that you’ll move it further as the gasket ages.
Watch as Gail demonstrates the position on several of our demo machines of varying style and age.
Keeping your equipment sparkling clean is just as important as the freshness of your coffee and dialing in your grind & tamp — in fact, without the former, the latter will be an exercise in futility. If we have to tell you that rancid coffee oils will adversely impact the quality of your shot, we’re sorry. But if we have to be the first, then we might as well do it right, right? So we asked Louie Poore, who specializes in educating professional baristas on proper equipment care for Urnex, to give us the rundown.
First, he introduces us to Urnex’s new Full Circle, sustainably-produced cleaning products — including a toe-to-toe comparison of Cafiza and Full Circle’s coffee equipment wash.
Finally, Gail shows us the newly arrived 1, 2, Brew Kit for Espresso Machines, which features the goodies you need to keep your machine in tip-top shape (plus a bag of Velton’s Coffee of your choice!).
We’ve heard concerns from customers on whether or not they should worry about trace amounts of lead or metal poisoning within their machines’ boilers and parts. So we’re going to break down the makeup of particular metals that are housed within your unit to ease your mind — and your fears of caffeine withdrawal.
Water corrosion is where it all begins and understanding your machine and what conditions cause corrosion — oxygen, water, metal and a catalyst — will help you manage and maintain your espresso machine.
Used for some espresso machine boilers and stovetop espresso makers as it heats up the fastest, ‘aluminum is protected from corrosion by increasing the amount of naturally occurring aluminum oxide (Aluminum + Oxygen) on its surface.’
As a mixture of metals, also referred to as an alloy, and under ideal circumstances, Sergio Louissant of LatteMaestro.com explains that this combination protects the aluminum but also has a quicker turn around time in breaking down the aluminum oxide causing the aluminum to corrode.
Chloride in tap water wears down the catalyst that breaks the shield that is the oxide layer between the metal and boiler water, as stated in a piece in the JL Hufford Coffee Tea Supporter Forum. This causes damage to aluminum parts over time so it is best to use filtered water or to regularly clean and descale your machine to slow down the deterioration process.
However, even though machines with aluminum parts are less expensive, that doesn’t mean they’re frowned upon. With its ability to maintain good resistance against corrosion, it just may take more of a closer eye and knowledge to understand the chemistry of it’s maintenance and when its time to switch out parts to prevent the quick deterioration of this material. Because the connection between aluminum and degenerative diseases such as Alzheimer’s is still unclear, many folks try to avoid aluminum as a precaution.
Very resistant to corrosion, stainless steel can be found in Saeco, Nespresso and Capresso machines. But its downfall is being the life of the party when it comes to hosting bacteria for a longer period of time on its surface compared to any other metal.
However, bacteria aside, since you won’t be cutting, dicing or chopping any raw meat on or with stainless steel espresso machine boilers and parts, as long as you keep the stainless steel within your machine clean, this material is ideal for espresso machines as it provides excellent heat retention and assures rapid steam function.
Unlike stainless steel and aluminum, espresso machines that use copper/brass boilers and parts, such as Rocket, Rancilio, Quick Mill, Pasquini, LaPavoni and Francis Francis, not only act like a repellent to those grimy germs and retain heat longer, but they also are the most resistant to corrosion than any other metal.
However, even with it’s popularity in higher end machines, some users are still left worried about the lead content in brass boilers.
While lead is added to some brasses, most manufacturers plate brass with nickel, such as Rocket Espresso, preventing any lead from leaching into water, reducing corrosion and acting as a barrier between brass and water.
But taking extra care when it comes to lead in products, it was in October of 1999 that the California State Attorney General sued 13 key manufacturers and distributors over lead content, leading to the reduction of lead content to 1.5 percent from it’s original 2 to 3 percent in products sold within that state. Following this action manufacturers were asked to reduce lead or to follow the requirement to warn consumers about lead content even if it didn’t have the ability to leach into materials such as water.
Hopefully this trend will catch up to the rest of the 49 states in the U.S. but for now, whether you choose a machine with aluminum, stainless steel or brass, taking precaution is key but knowing how your machine works and what it reacts well with will also keep you happy, healthy and caffeinated.
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.
If you’re anything like us, you probably used your gear’s user manual for one of three things:
- To ineffectively swat at flies, yet one day you accidentally killed one and couldn’t bear to keep the gut-stained book around.
- To prop up the uneven handmade bookshelf lovingly made by a friend/parent/spouse/sibling/child that never sits right on the wood floor.
- To start a fire in the fireplace to enjoy while sipping on a delicious glass of chai spiced wine. (Guilty!)
Or, maybe you just recycled it by accident. Whatever the case, the fact of the matter is that now you have no wisdom to guide you. We created our manufacturer manual repository over at Brown Bean to connect you with the source code. We have manuals for a lot of models both current and historical, so if you’re looking for tips on how to perform maintenance or need to find out what that error code means, check ‘em out.
Don’t see your model there? Leave a comment here and we’ll see if we can’t track it down and add it to the repository.
One of the first demonstration videos we did was Gail using how to pull a shot on the La Pavoni Europiccola 8 manual/lever espresso machine, which we followed up on several months later by demonstrating that same machine’s steaming functionality.
We recently decided to take the Stradivari 16 out for a stroll to see how it compared to the other version. Watch as Gail pulls shots, steams and uses the included cappuccinatore attachment with this machine.
Seattle Coffee Gear’s monthly newsletter, The Grind, landed in an email box near you today — and if it wasn’t near enough for you to actually read it, you can do so here on the site or make sure you get up close and personal next month by signing up for future editions.
This month, we talk about the different functional types of espresso machines, include a recipe for Indochine Lemon, point you to our manufacturer manual resource on Brown Bean and introduce you to a few new products we have in the store. What you won’t see, however, is The Grind Special, which is for subscriber-eyes-only. Sign up to get that little bit o’ goodness every month.
