Im sure that youre aware that the general sentiment with regards to superautos is that they dont produce great coffee and they are more prone to breakdown due to their complexity. If you are going to be doing high volumes, the machine will make things relatively easier for an untrained person behind the counter, but if and when anything goes wrong, youre out of business for good.
You ought to go and check out the superauto before you decide. Take along the coffee that you intend to use in it, taste it and decide if you would return for it. Even if you have a location where people are basically forced to get coffee from you, producing a great cup will have a significant impact on your profit.
If you are going to do high volume takeaway, I would suggest looking into the LM Swift auto-tamping grinder. This grinder was originally developed for Starbucks and gives you the advantage of being able to pair it with a traditional, reliable espresso machine. The grinder doesnt produce quite as sweet a shot of espresso as a great barista with a really hardcore grinder, such as a mazzer robur, but it does streamline the work flow. The taste difference is very hard, if not impossible, to pick in milk. I know of one espresso bar that has a robur, put a swift in and went from 30kg to 60+kg a week in increased takeaway business!
If you are in Melbourne, send me a PM and Ill put you in touch with a few cafes using Swifts.
Regardless of what route you intend to go down, make sure that you give your supplier a thorough grilling about what sort of technical support you can expect!
