Hard water - not filtered by water board?

It is interesting in the case of coffee that the right amount of hardness is critical for getting the best possible brew.

I was at a lecture on the chemistry of coffee making (sponsored by a maker of commercial barista coffee machines) and with an expert present with all the methods of making the stuff and tasting some very exotic single estate coffees and single species/varieties.

The most fun was him making coffee with different qualities of water:

  1. Pure water (reverse osmosis potable grade)
  2. Newcastle tap water
  3. Evian water

It was recommended to taste them in that order too.

#1 was OK but rather soft, dull and lacklustre. #2 was a very nice balanced cup of coffee. #3 was disgusting with free bases that tasted really bitter.

Turns out Newcastle tapwater is almost perfect for coffee making.

Yes my parents had an old-fashioned kettle - the sort that was low and wide, rather than tall and narrow like a jug - and it was made of "silver" (nickel?) plated steel. That worked for as long as I can remember. It may have been a wedding present, in which case it probably lasted about 25 or 30 years. Like you, I think my parents replaced it for a jug kettle that was easier to use, turned itself off and didn't leak steam from the lid onto your hand as you picked it up by the handle to pour it - jug kettles have the handle at the side rather than in the path of any steam that may come from the lid/spout.

you don't need it to drink either - it tastes awful

What prevented the soap leeching into the water after that? Obviously he'd wash out majority of the soap residue fairly well, but I'd have though the water would always taste very slightly soapy afterwards.

After many years of use, my parents' cistern had a limscale tide mark round it - in fact it had several where the cutoff had been set at different levels. Being a porcelain cistern (unglazed on the inside), the limescale clung very tenaciously and couldn't be removed, so we left it. The toilet still flushed fine. With a plastic cistern you can chip the scale off as long as you do it frequently and don't let too much build up.

No, but they fur up. Then bits of the fur break off and get into your tea/coffee.

Had you not heard of bakelite? You could almost put that on a gas stove.

What d'ye mean "breaks it up"? Are there little imps with miniature hammers who swim up and down the pipes chipping bits of limescale off?

Russell Hobbs K2. If you boiled it dry the big round connector shot out of the socket.

Yes they do. Our such filter fell to pieces as it got furred up.

I've added to your long URL. You're welcome.

Now: how is that thing supposed to work?

RO water is pure, and that is a problem. The best water has some minerals in it. Some bottled water is RO processed and then some minerals are put back in so it has a good taste.

The only one that matters, in Delaware. Am I right?

When I rebuilt our kitchen I removed a length of old iron pipe which had bee in use a the main supply to the kitchen tap since the house was built - about 60 years previously. It was virtually clogged. No way of seeing through it. But then we live in an "insanely hard water area"

No available: model too old. Kettle itself works fine, although I could wish it turned itself off slightly sooner. But it'll soon be moot as we are getting a boiling water tap.

Yes, similar to that. My parents' kettle didn't even shoot the lead out of the kettle. I think the difference with theirs was that the handle was solid Bakelite right from the switch/socket/element connector on the back to the point where it attached near the spout, rather than having metal rods and only the handle in Bakelite. I'm wondering whether theirs even had a switch or whether you needed to switch it off at the wall socket - not sure about that.

Certainly it had a proprietary mains plug/socket like the K2 rather than IEC C13/C14 which I tend to refer to as "kettle connectors" because *modern* kettles have them (as well as most other devices like PC PSUs). As a matter of interest, what's the name for the "clover-leaf" 3-pin plug/socket that's used for some laptop-charger mains leads.

no they don't break, they just get the element or the sides coated with limescale.

The question still stands.

Obviously not his leaking brain (and yours probably too).
