Actually that´s the main historic reason for Eastfriesian blends to
contain such high amounts of Assam, usually 90%. No other tea that
made it over here back in the old days benefitted so much from the
extremely soft, slightly acidic water they have here. From my
experience an average Assam can handle quite a broad span of water
hardness resulting in some interesting changes of flavour and colour
of the brew. However, most Frieseans seem to like their tea water
soft, so some folks took to collecting rain water while other folks I
know over here don´t travel without some canisters of local water in
their cars.

But rainwater would have essentially no minerals at all. So there is
a tea, after all, suited to demineralized or distilled water? Amazing.

On the other hand I have to use bottled water [Volvic] or add some
minerals for my Darjeelings, using water straight from the tap results
in a flat and downright boring brew.

Could you please expand on this fascinating hint? I've often thought
it should be cheap and environmentally responsible to try to emulate
good mineral waters by adding the right salts to tap water.

BTW: having been born and raised in a city with miserably hard water
that is totally unsuitable for any sort of tea [but somehow great for
coffee] this leaves me speculating on what effects a worldwide
improvement in the quality of tap water would have on the popularity
of tea.

Maybe it isn't that simple. What would be an improvement in water for
one tea might harm another tea.

During my years in Eastfrisia I´ve enjoyed some cups of Eastfrisian
blends that had been prepared that way and I really liked the way
those teas tasted. But then I have to mention that eastfrisian blends
are almost never drunk straight but with a rock of sugar and a
carefully applied layer of thick cream.

I remember another water/minerals related discussion on rfdt where
DogMa threw in some fascinating facts on adding minerals [gives me
something to google for tonight].
Anyway I tried all kinds of minerals from my stash [homeopathic,
Schindele, "Dr.Schüßler Salze", Basica, ...] with all kinds of
results. Talking about Darjeelings the best additive I´ve found so far
- inspired by talks with my tea guru is .... Darjeeling soil, namely a
pinch of "holy" earth from Arya Tea Estates, Happy Valley, North
Tukvar and others [sue me folks, .... smell another income source
A. ?]
I just throw it on top of the leaves before I add the water, a little
more than 0,5g/l.
Again it could be all 100% subjective, like the driving force behind
my never ending quest for the "optimum" brewing parameters, but
somehow more nuances appear to make it through, not necessarily those
of the earth but those I remember from having drunk that specific tea
up there where it comes from.
YMMV.

Certainly so, but having traveled a little bit I found the water from
quite a few places - no matter if cold from the tap or boiled entirely
undrinkeable or in our case unsuitable for the preparation of any tea
I know of.

Yeah - be a heck of a lot more convenient than schlepping water home
from the market. I've tried a few saltoid addenda, including sea salt,
garden lime, crushed dolomite and alum, but none worked very well. When
the need seems to arise, I just add a small splash of bottled mineral
water - full strength is far too much.

A critical option is brew vs. spike: add minerals to the brewing water,
or to the brewed infusion off the leaf. They both work, and I usually
can't tell the difference. (Of course, I can't tell tea from coffee
without a look at the label, but that's another story.) This casts some
doubt on the extraction-variables case - though whether or not ions
matter much in brewing (as distinct from effects on the tongue, or in
binding solutes in various ways), I remain convinced that extraction is
indeed affected strongly by small changes in pH.

Danica has some stuff that's designed for re-mineralizing filtered or
distilled water... it seems to work Ok. You just put a few drops in the
water before heating it.

Ask a local homebrew shop for "Burton's Water Salts." This is a mineral
mix that is intended to duplicate the mineral water composition at a
particular site in the UK. When added to distilled water it gives you
a nice soft mineral water.

This makes sense, but I suspect it's more than just pH too.

Dan Cong? Why? How do you ussually brew it? I would use water around
slightly before boiling degree, I admit that it can get nasty with
dan
cong, certain breed can go bitter if overbrewed as well as depending
on your brewing techniques you might get more infusions or lesser
infusions.

[Michael Plant]
It goes bitter when pushed too far, right? But, for me bitter is not bad. Anyway, I fill my gaiwan or gungfu pot chockablock with Dan Song and then, using water just off the boil, I do instantaneous steeps for the first several and then add seconds slowly from then on. It works for me. BLC I've ruined, DC seldom.

DC is a good example in my opinion of tea which provides, as Lew mentioned in another context, different pleasures brewed in different ways. Although I never bring the water temperature down, I do increase and decrease the amount of leaf and the length of steep occasionally to vary the taste and style: Generally, pushed harder, I get more bitterness and more finish. But, pushed like that, there can be a harshness up front.

Michael

Sorry for the late reply, Jazzy and Michael. It's hard to get a
consistent and intended result, and I'm still trying different brewing
parameters that involve leaf : water ratio and steeping time. Yes, it
gets bitter easily when pushed (not) too far, or gets too astringent
with some types. It is an oolong that I find very sensitive to
temperature, time and quantity of leaves used. To complicate matter,
there are many roasting level of the tea, and each type is somewhat a
different animal, requiring its own learning curve to get it "right".

What I "usually" do (I have not settled with any adopted MO) with the
high fire DC is to fill 1/4 of my gaiwan or Yixing with leaves and use
just-boiled water. No direct hot water contact with the leaves (I
slowly pour the hot water onto the lid of my Yixing pot -- the lid
opens halfway and slants, so water slides down into the pot -- OR onto
the sides of my gaiwan in circular movement). Short infusions
starting with about 5 - 7 secs. Lid of vessel is opened right after
pouring to prevent the leaves from getting over-cooked.

I use much less leaves with the greener Dan Cong, as it can become
pretty nasty very quickly, but quite lovely when controlled properly.

Does anyone recommend brewing DC with lower temp? Toki of The
Mandarin Tea blog does cold brewing with his Dan Cong (here is a guy
who knows his Dan Cong and where to get great stuff from).

Michael, I've never done that technique before with DC (chockablock --
water just off the boil -- instantaneous steeps for the first several
and then add seconds slowly), although that's what I do with Wuyi
Yancha (my "chockablock" maxes out at 3/4 of the vessel, though --
more than that is too toxic for me).

Comments and advise are appreciated. Thanks.
