Overview
The newest Ascaso espresso machine to hit the United States earned its name of Ascaso Steel Duo Office from its reputation as a great office espresso machine. It's not just corporate America that appreciates the features and power of the double boiler machine, many coffee geeks have flocked to the Steel Duo for its features and low price point. The Ascaso Steel Duo has two pumps, one is always devoted to espresso extraction and the other to steam production. There is a dedicated boiler for espresso and a brass thermoblock for steaming. The differences between this machine and the Steel Duo Professional is that this machine includes a pod basket and has a slightly smaller coffee boiler.
Highlighted Features
- Brushed stainless steel finished body over a black enamel painted steel frame  
- Independent steam thermoblock with separate on/off power switch (lower panel) and the steam activation switch is on the top panel (top right)  
- Independent water activation switch (lower right of top front panel) which activates a separate valve for hot water through its own water pipe  
- Low water reservoir cut-off: when water reservoir is near empty, the cut-off switch will not allow power to the heating element nor the pump.  
- Brass boiler capacity: ~225mL  
- Brass boiler for the coffee and a separate thermoblock for steaming, each with their own independent pumps  
- Heating element is located on the outside of the boiler so that a lack of water will not damage it  
- Three-way solenoid valve allows the immediate removal of the portafilter when the espresso extraction is completed. The three way valve also allows the user to backflush the grouphead for regular cleaning.  
- S-2 Autoprime valve acts as an air release valve to remove air that may be suctioned up with the water from the reservoir  
- Comes with a pod basket.  
Standard Features
- Brass portafilter handle with plastic grip  
- Temperature gauge  
- Drip tray slides forward for easy cleaning  
- Swivel based steam wand allows easy rotation of steam wand over steaming pitcher  
- Frothing aid attachment makes it easy to froth milk for cappuccinos and a 3-hole tip is included as a replacement for the frothing aid.  
- Passive cup warmer on top with guardrail.  
Steaming Milk
- Hit the steaming button and watch the indicator light to know when the temperature has been reached for steaming.
- Before turning the steam nozzle, point the end of the steam wand into an empty container or point it towards the drip tray. This is to get rid of any water that might first come out when you turn on the steam wand.
- When dry steaming begins exiting the steam wand, you can turn it off. You are now ready to start steaming your milk.
- Do not fill your milk pitcher more than halfway full with cold milk
- Make sure the tip of the steam wand is fully submerged before you turn on the steam.
- After you begin steaming, you can raise the steam wand so that the tip is barely submerged. If the tip is submerged too much the milk will begin to squeal meaning it needs more aeration. If you bring the tip too far out you will hear a heavy chirping or sucking sound. This will result in big bubbles and a possible mess.
- You should aim for slight chirping up until the milk reaches room temperature. At that point you can submerge the tip of the wand to one side of the pitcher to create a swirling motion. Continue this until the steaming pitcher becomes too hot to the touch or a couple seconds after you have to take your hand off of the bottom or side (this should be around 140°).
Accessories:
- Portafilter with Double Spout.
- Single and Double filter basket.
- 57mm Aluminum Tamper (Machine actually takes a 58mm so we recommend purchasing a 58mm tamper in the options above)
- Pod Filter Basket
- 3-Hole steam Tip
- Coffee Scoop
- Instruction Manual and Quick Start Guide
- Ascaso Cleaner Packet
Pros
- Perhaps the cheapest machine available that includes a dedicated thermoblock for steaming.  
- Pod basket included  
- Dedicated hot water tap  
Cons
- The dedicated boiler assures that hot water is not being used for steaming, but it is still too small to handle large quantities of drinks in a short time frame  
- The temperature gauge is known to be volatile  
Product Care
- Plain water backflushing should be done at least once a week. To backflush, use the portafilter's backflush disc. Take out your single or double basket and securely place the blank insert into the portafilter. To perform a plain water backflush, place the portafilter into the group head. Then raise the brew lever all the way up for 15 seconds, and then lower it. Water will forcefully discharge out of the bottom of the group into the drip tray; this is normal. Repeat three to five times.
- Backflush with detergent like Cafiza (see options above) once every fifty extractions.
- Warranty: One-year parts and labor provided by US distributor. (Shipping costs excluded)

(For a guest barista review, click here.) Anfim's Super Caimano espresso grinder, upon its initial release, was a solid addition to any high-end coffee house. It featured a 75mm flat burr set that helped to give a very consistent grind, allowing baristas to rely upon it for excellent shot-to-shot uniformity. When dialing in a coffee, the Super Caimano had 70 holes in its adjustment collar to allow for tinkering between shots. Now, however, Anfim has added an additional 20 spots for a total of 90 holes in the adjustment collar. The benefit of this? When dialing in and finding the sweet spot for any coffee being used to pull shots of espresso, a key factor the barista must take into consideration is the size of the grind particles. Yes, uniformity and consistency of those grind particles is also key, but the ability to make tiny, incremental adjustments is always helpful when striving to find the right balance of all a coffee's characteristics when pulled as espresso.

We've looked long and hard for a scale that we can recommend for our avid manual brewing friends. The scale needed to have a high weight capacity, fast response time and precision calculations, and the ability to disable the auto-off feature to ensure the scale would not shut off mid-brew. The Jennings CJ4000 is the first scale we have offered that meets all of these requirements. With a 4000 gram capacity, accuracy to .5 gram, and the ability to disable the auto-off feature, the Jennings scale is the perfect companion to manual brewing.
