Excessive coffee consumption?

and that’s why I drink tea.

I drink Catunambu all the time out and about, but for some reason it comes out slightly bitter in our machine. We’ve on our second De’Longhi bean to cup machine, and have tried a multitude of beans over the years, the ones that suit both the machine and our palate have always been Lavazza.

It’s a pity, I can get Catunambu for about €7 per kg, or slightly less if I buy in bulk.

The most likely culprit is your water.

1. Ideal brew temp is 196 - 204 F. Too hot or too hold can result in bitterness.

2. Mineral Content in your water has a DRAMATIC impact on “the cup”. Your water supply may have too many minerals, bad minerals, or the wrong combination of minerals.

It is pretty easy to experiment - try using some quality spring water and see what that does for you.

Oh - and always run a quick flush after a brew cycle - it helps avoid most of the buildup in the brew head.

It’s never had anything other than spring water in it and the temp is circa 94c.
