My coffee maker uses a water filter -- it really does improve the taste.
Do you have a Brita or a Pur filter? You could use filtered water instead of plain tap water in your coffee maker. That's what my parents do.
Don't have any of that...
We have an espresso maker, which hasn't been used in a while. (It got packed away when mum's friend did the first half of a kitchen renovation, and it hasn't been brought back out yet.) Usually, we use the kettle and instant coffee.
It's not as good, but it's simple. A spoonful of sugar, a spoonful of coffee (in a cup), add boiling water, add milk.
And we do have a water filter tap... That's where the foul water came from last time. We had the filter changed, and the problem was still there. So it must be the water itself... Adelaide is renowned for having shit water, anyway.
But today's bad coffee wasn't the fault of the water, I think...
I just had a mouthful of milk. Ewww! It tasted funky, and not in a good way.
So I checked the date on it. Today's date. So probably not all the way off, but not in good shape...
So I'm going to have to go out to the shops and buy milk.
I can still taste the milk... Yuck.
