Stale coffee, blunt blades, leaking group head seals - An everyday story of a low volume coffee site

As a coffee roaster who wants every customer to enjoy great coffee it can sometimes be a frustrating business, particularly when dealing with smaller cafes.

An experience I encountered the other day makes you appreciate that it's not easy to serve great coffee when it's just one of a long list of items from staffing issues to the next rent payment that you need to worry about.

If you are reading this blog and the above sounds familiar, then can I suggest that you pay real attention to the following critical areas in your coffee making day.

1. Review how much coffee you are actually selling, if your usage is below 1 kilo (about 140 cups) a week you should be considering using individually packed pods. The coffee beans being an organic product stale quickly once open to the air, whereas pods are designed to only be opened when they are needed. They seem expensive against the price of beans, but will deliver a consistent cups of coffee whilst you try to build up those sales.

2. If you can justify using beans, then don't overfill the coffee grinder hopper. At most a 1/3rd full will suffice. Better to top up from the bag often, than to have the coffee beans getting stale in the hopper. Just to add that once a bag of beans has been opened, ensure you squeeze as much air out as possible, and then store in a cool place.

3. Don't grind too much coffee, again less and often are two words that if followed will deliver a better tasting cup of coffee. I would suggest throwing any ground coffee left over away, but you'd probably say that that was a roaster speaking!

4. Coffee grinder blades - Their condition is vital to the quality of grind you get. Worn blades will not deliver great coffee. As a rule of thumb, every time you have your espresso machine opened up for insurance purposes, it's a good idea to get the grinder blades changed at the same time. It's not that expensive, and will benefit coffee sales.

5. Before making any coffee, ensure that the machine is at the correct operating temperature. Machines left standing doing nothing will not deliver great coffee if used immediately after a quiet period. Ensure a couple of cup-fulls of water are sent through the group heads prior to making a coffee.

6. Cleanliness - Do a "chemical" clean of the group heads of your machine at least once a week. A water flush at the end of the day is vital to stop the heads clogging up, but a chemical clean will break down any stale oils left hanging around. Also don't forget to clean the group handles and baskets at the same time. Baskets may look clean from the top, but take them out and you will be surprised how black the underside can become. It will all go in the cup of coffee otherwise.


7. Steam wand cleaning - Ensure that milk isn't left hanging on the steam wand, it will clog up the holes and can cause a major hygiene problem, it doesn't look great either to a potential customer and to my mind makes a statement about the place before a coffee is even made.

There I hope that helps those of you who don't sell that much coffee for whatever reason. As a roaster whether you are large or small, we only want you to sell great coffee.
