Trader Joes coffee + espresso machine
I bought the Gingerbread coffee yesterday and tried to brew it in my espresso machine(the coffee was ground right) and something about it gunked up my machine to where it would brew about half of the water I put in and the rest I had to let out as steam. I then exchanged the Gingerbread for normal french roast and it wasn't quite as bad but it gunked up a bit. So far I've only used Starbucks and Larrys Beans and neither of those have been a problem so I'm not sure what the deal is.
Has anyone else had a similar problem?
Our espresso maker's instructions specifically say not to use flavored coffees or especially oily beans. I don't know quite how the flavor-adding process makes a difference, but you might try steering clear of the flavored blends.
What you did is known as choking the machine. Usually caused by grinding too fine or tamping too hard, or using too much coffee in the portofilter. Without knowing what kind of machine you have,or saw what you did, I would still guess this is the cause.
I know I should mind my own business, but I would also advise you to buy a 'good' burr grinder. You will be much more satisfied with the results of your espresso machine.
thanks for the replies, I should buy a grinder, I've just been grinding it wherever I buy the coffee. I have a Krups machine, it probably says the same thing about using flavored coffees, I guess I just didn't think this was the same because they flavors are just spices that end up being ground up with the coffee. I figured it was the same as some people putting cinnamon in with the coffee. ah well
