New kettle

Did your previous kettle need descaling? The new one obviously won't, that could account for the different taste.

I stupidly bought a really cheap kettle. I tried everything but nothing worked and I ended up taking it back as tea and coffee tasted foul! The more expensive one had the same issue but after boiling it with vinegar it was fine. Worth a try!

I find this with a lot of plastic kettles no matter what you do to them.
Is it metal or plastic?

I always put one of those little scale catchers from the hardware shop in.
£1 each and so efficient.

Thanks everyone. It’s a Russell Hobbs metal kettle. The coffee tastes ok just the tea that’s a bit off. Even changed the tea bags ! Maybe it’s the water, only been in this house just under a year so suppose it could be that. Brought the previous kettle from the previous house and that seemed ok. It was plastic. How much vinegar would I put in and which type. Have malt and white wine . Will try anything, it’s driving me mad !
