Commercial Expobar Brewtus IV with Vibration Pump

The Coffee Grinder – we have discussed coffee grinders here in the past and defined what a weight measuring coffee grinder can do. Now I’m going to tell you a seldom revealed astonishing fact; the quality of the coffee grinder directly affects the taste and crema of the espresso!

For instance you can experiment starting with a very good espresso machine like the Gaggia Classic. Make espresso shots using grounds of the same coffee from various coffee grinders like a low end burr grinder, then go up in quality to a better home burr grinder, then to a prosumer-commercial burr grinder and on to a high end commercial conical burr grinder. You will actually notice how much better the espresso is using coffee grounds from each coffee grinder!

In keeping with the spirit of our espresso-as-science experiment and the ability to be consistent, we had talked about the very good Baratza Vario-W Coffee Grinder.

The next step up, in my opinion, would be a prosumer-commercial grade machine like the Ceado E37 Coffee Grinder, which is a programmable dosing grinder that has amazing burrs and will give you a better espresso because of the burrs and the design of the grinder.  It also lets you program the dose electronically based on grind time. So again you can be consistent in the amount of coffee you use. Here is a link to learn more about this amazing grinder. Ceado E37 Coffee Grinder. 

The next step up to a commercial grade machine may seem like a little much for home use; however, a  great choice would be the Mazzer Kony as it has conical burrs and it is also available in an electronic version for producing consistent doses of coffee grounds. This coffee grinder or any commercial conical burr coffee grinder would permanently end any further need to upgrade your coffee grinder. A coffee grinder like this will absolutely give you the best chance of making a truly superior espresso.

Looking at the coffee grinder as one of the controllable variables in our espresso-as-science experimenting we find that selecting the best grinder we can afford is one thing we can change and get a predictable result. That is, if we keep everything else the same, tamp, amount and type of coffee, and the size of the shot, then adjusting the grind and tasting the shot results will determine what grinder and grind fineness will give us the best tasting results.

For most people the grinder and grind settings would be the variable that would give them very noticeable results quickly.

The Espresso Machine – So far we have looked at many of the variables involved in making great espresso. Another variable is the espresso machine. Many espresso aficionados consider the espresso machine to be the most important one. I do somewhat agree that the machine is an important part of producing quality espresso. 

With the correct machine you have the potential to make a great tasting shot of espresso. I say potential because so many factors go into making a great espresso. Many of these factors are going to be based on the user’s knowledge and skill at crafting an espresso from what they have to work with.  Again if we look at this as a science experiment one of the factors that can be controlled if you have the proper machine is the brewing water temperature.

Espresso coffee taste will vary considerably when brewed at different temperatures. I always tell people about wine and how to relate wine temperature and how it affects wine almost the same as coffee. Actually wine and coffee have many similarities as far as how they are cupped, tasted and have different characteristics based on where they are grown and even how good or bad the growing season was.

Back to temperature and wine; If you order a really good bottle of white wine somewhere and it is kept in the beer cooler at near freezing you know when you get that wine it will only taste cold. It is not at the proper temperature for the wine to let you in on all the nuances and flavors the vintner has worked so hard to get in that great bottle of wine. As the wine warms up and gets to the proper temperature for serving then you start to notice the flavors of the wine such as oaky, fruity, flowery, and all the other great descriptions of the wine.

Coffee is the same way. Temperature plays a very large roll in how exactly the espresso will taste.  The whole idea of looking at this as a science experiment is to learn how you can control many of the variables in making espresso. Having a machine where you can control temperature is a huge advantage at being able to make an espresso that may be the best you have ever had.

Spending your money on the right equipment will give you the potential to make an espresso shot that is downright amazing.  The ability to control temperature is going to let the espresso have different tastes. You may be able to pick out chocolate, berry, caramel, fruit and also something like currants. Notice the similarity to wine descriptions.

If you invest in a machine that allows you to control the brewing water temperature, like one of my favorites the Expobar Brewtus IV Espresso Machine, and you  keep all the other variable parameters consistent, you will get to the point where you know exactly the temperature that will yield the best tasting espresso coffee.

Having an espresso machine that will brew at exact temperatures will certainly help us in our quest to make the perfect shot. Since our love of espresso coffee and our ability to be scientists should have a goal and a plan to get there I will discuss how this all ties together in part three of espresso as science and perhaps reveal what this all means!

What I Like About The Brewtus

Double Boiler The Brewtus has a double boiler. What this means is you have one boiler for steam and another boiler for brewing espresso. The great thing about a double boiler is it gives you great temperature stability for brewing espresso. It is interesting to note how the espresso taste can change when brewing at different temperatures, The Brewtus with a double boiler allows you to brew at exact temperatures shot after shot. The double boiler is one of the most coveted features among espresso fanatics and is found on only the best machines.

PID The PID is what gives the Brew boiler the ability to brew to exact temperatures. PID stands for Proportional, Integral, and Derivative. Here is a simple explanation of what it does in regards to the brew boiler: a PID is a computerized, digital thermostat. It monitors and learns how your boiler heats. It then will accurately control any temperature you want it to maintain. The advantage is it is a variable you can control as you learn to make repeatable great shots.

E61 - The Brewtus IV is outfitted with a chrome-plated brass E-61 Brew Group. This type of group head is well known for its ability to help maintain exact or in this case calculated temperature stability. It does this by using a thermo siphon system that circulates hot water from the boiler to maintain group head temperature. The Expobar Brewtus IV machine now offers a concave pre-infusion chamber that allows the user the ability to control pre-infusion by using the lever. Many people feel that by experimenting with the pre-infusion you can really control the taste of the coffee.

Plumbing options We felt it was important to give the Brewtus IV many options for plumbing. We have covered all the bases. You can use it as a pour over with the vibration pump reservoir model. You can hook a water line directly to it with the Rotary pump model. This model is quieter and also will let you attach a water softener/filter system to protect your machine. You also have the option in a reservoir model that can be plumbed or you can use it as a plumb in version. So with this model you can use it either way and it is fitted with a vibration pump.

Construction and Durability We are very proud of all the positive feedback we get in regards to how much people love their Brewtus. Many of these people use their machine multiple times a day and love not only the great shots they get but also how well the machine works and holds up. We have done a great job of constantly improving the machine realizing that one of the most important things is the reliability and durability of the machine. We are proud of our efforts and how well the Brewtus line has held up for us.

What I would improve:

Size- The Machine especially in the plumbed in version may be a little larger in size and heavier then people expect.

Larger Cup Size Right now the Expobar IV It fits a 4 and inch cup underneath the spouts. It would be nice if it could fit a larger cup say about 7 inches for a larger travel cup or a 16 ounce cup. But it certainly is not a deal breaker because if it is made to take a taller cup it may not fit under a normal counter.

If you are curious about the pre-infusion feature available on Expobar Brewtus IV machines, then this is one video you shouldn’t miss. I’ll go into detail about how pre-infusion works and what makes it such a great feature for espresso lovers.
