Re: Cake different from testing in shop - what went wrong?

Folks who work in a tea shop generally brew better than the average bear too... for obvious reasons.

This is a great site for the mineral water aficionados. I just drink Brita-filtered tap water or boiled tap water (like most of HK) down here at work since I haven't brought the spare Brita down here yet. Incidentally, HK being granite and basalt (volcanic rock), our local water should have a somewhat similar mineral content, although of course our water is treat and diluted with treated river water from China.
Of course, not everything in the water is listed on the label, particularly in China, so if it tastes funny, run.
Distilled water would have the lowest number of solutes. I may have to try some later today to see if it makes a difference.
Mineral water is a great business: even in the US, lots of 'spring water' just comes from municipal water supplies.
Their sample was loose in a Dayi envelope as far as I remember.MarshalN wrote:Something else - if it's a cake that they've had out for a while as a sample, the airing out might have done something to the cake, although usually not drastic.
Actually the girl in the Dayi shop was really awful at gongfu brewing, which doesn't surprise me since it's the most commercial pu erh brand in China.wyardley wrote:Folks who work in a tea shop generally brew better than the average bear too... for obvious reasons.

I tried it today with the purified water but the tea was very meh again.
I guess I'll just chalk it up as a bad cake and store it for a year or two or give it to a friend.
Don't be too quick, try it first later again. Sometimes Pu Erh can go into some sort of hibernation stages, tastewise. Also, a few weeks of airing a cake after breaking it up does significantly improve the taste.ChengduCha wrote:Their sample was loose in a Dayi envelope as far as I remember.MarshalN wrote:Something else - if it's a cake that they've had out for a while as a sample, the airing out might have done something to the cake, although usually not drastic.

Um, minerals don't go anywhere, in fact, the more you boil it the more concentrated the minerals get as the water evaporates. That's how you get deposits.chrl42 wrote:Puerh is brewed in boiling water, once the water is boiled many minerals will be evaporated..pretty much on par with purified or distilled water.
The Chinese has a long history discussing water, during Tang dynasty they considered mineral water from high up mountain the best,
Qing dynasty is the opposite, for example Qian Long tested all the water from famous wells to pick the lightest water in China, some considered snow water, the lightest, the best.
But I do know Wuyi Yancha prefers the mineral water, and it's written in many Gongfu scripts...whatever the base water and its mineral contents, I've heard once it's boiled they will be gone.
Curiously, depending on the type of mineral dissolved, boiling will reduce the mineral content of the water. The alkaline earth metals (calcium, magnesium...) are not highly soluble in water as carbonates, however their bicarbonates are much more soluble in water. The bicarbonate ion exists in a chemical equilibrium with dissolved carbon dioxide in water. As water is boiled the carbon dioxide is driven off, and the bicarbonate ions remaining convert to carbonate ions and carbon dioxide, and are driven off as well. The remaining carbonate minerals will rapidly precipitate out of solution, until the solution reaches the saturation point for that carbonate (at a lower level than before). So if your water is super-saturated with bicarbonate minerals of calcium and magnesium, boiling it will, in fact, reduce the mineral content. This, not the loss of water due to boiling off, is the reason you get mineral scale buildup in the container you boil water in.MarshalN wrote:Um, minerals don't go anywhere, in fact, the more you boil it the more concentrated the minerals get as the water evaporates.

I think good water and bad water make a big difference, but different bottled water may not make a big difference. However, some nongfu water I had did taste sour to me, although their commercial always says it taste sweet
I generally don't use any bottled water. But I'm lucky to be close to good water source so far wherever I've been (except during my short trips to New Mexico and the real Mexico...)theredbaron wrote:gingkoseto wrote:Since it's a 2011 shu, probably resting time is important.

Different brands of bottled water make a huge difference, just try them side by side. There are brands that give you right away a ton of scale and at the same time transform your high quality tea into a cheap supermarket brew. Other brands, like the already mentioned Volvic or Fiji will give no scale and the teas will be clean and shiny.

But I'm surprise to hear some bottled water could be so terrible. Shouldn't some agency shut the factory down? It's terrible that plain water costs that much money, and more terrible when it's bad.
On the other hand, scale is not necessarily a bad thing (bad to the kettle, though). Scaling means what we don't want is solidified and won't be drunk up. A lot of good mountain spring water would produce scale but the water is good. Usually what's worst is the bad mineral that we don't want and don't precipitate into scale either.
