Airing out tea

February 13, 2010 · 1 Comment

Some of you already know this.  You’re supposed to air out a tea, if it’s a traditionally stored puerh.  The problem with traditionally stored tea is that if you don’t air it out, all kinds of nasty, “storage” smell remain, and will affect how much you can enjoy your tea.

This point hasn’t been illustrated as clearly as what I recently did with a bag of tea that a friend brought back for me.  It’s from one of my favourite stores in Hong Kong that sells such things.  The tea is very wet stored — you can smell the storage from a mile away, and is not for those who don’t like that kind of taste.  When I first opened the bag and brewed some, it was horrible.  It smelled fishy, moldy, rotten.  The first few cups I couldn’t drink at all.  I started wondering if I got a bad batch.

The friend, however, knows what he’s doing.  When he visited the shop, he noticed that the stuff in the jar, which is what they usually use to fill these smaller orders, was rather moldy.  He thought it better to buy some that were “cleaner”, so he asked the owner to show him a few bags of the stuff from the back.  The owner duly complied, and my friend picked out some from a good looking bag.  This is all good, except, I think, because the bag was relatively unopened, the tea still retained much of the storage smell, and it’s not pretty.

Fast forward two weeks — I’ve had the bag opened for that long, just sitting on my table.  I thought it probably best to let it air out a bit, to release some of the more “toxic” flavours from the bag.  I tried it again yesterday — no more fishy smell, or rotten carcass.  It’s gone.  Now, instead, much of the sweeter note that I love from this store emerged.  No problems — it’s just a matter of airing out the tea.

Spoilage

January 8, 2010 · Leave a Comment

I opened a bottle of spoiled wine yesterday.  It was not a great loss, as it was only a cheap Cotes du Rhone that I had kept for a few years.  It went through various types of poor storage, including a year and half in a U-Haul storage facility.  The cork probably dried out at some point, and nature took its course and turned it into vinegar.

This reminds me of the risks inherent in storing tea as well.  Humidity, for the most part, is not a risk factor in much of the US, but depending on the environment in which you store the tea, it can affect the tea negatively, perhaps fatally.  I am always reminded of this accident and wonder if the tea I have stored in my parents’ home in Hong Kong is safe and sound.  Granted, it’s not a shed on the hill, and so it’s probably not nearly as humid as the storage conditions of those tea, but Hong Kong can get somewhat wet at times, so it’s still a bit of a risk factor.  I tried to minimize the risk by having the teas stored on a few shelves near the ceiling and away from the windows and light, so that they are, for the most part, shielded from excessive moisture, heat, and sun.  Yet, since I am not there, it does worry me that some, if not all, of it might turn out badly.

This is of course one of those risks that we all have to take when we decide to keep things like tea or wine at home.  They can age poorly.  If you leave it to others, they assume the risk, but then you have to pay them for assuming that risk in the form of higher prices.  Nothing is free in life, after all.

Storage

December 12, 2009 · 6 Comments

These days I’m storing my tea thus

The cabinet is small, but just big enough to hold all my cakes and random puerh chunks.  My aged oolongs I leave in the plastic bags and in drawers that are away from light and heat.  There are really a few goals when you store a tea.  Obviously, you hope it’ll improve, but more importantly, you have to first make sure that it is safe.  A tea that grows unknown things is not going to improve, and that, I think, is a mistake that is sometimes made in an effort to speed up the transformation process of the tea.

From my experience with Taiwan, Hong Kong, etc, it is fairly dangerous to leave tea out in the open in an environment that is fairly humid.  If done improperly, mold grows very quickly, often within a week of continuous rain with no reprieve.  I think basically if the leaves are sufficiently moist, you’ll get mold growing, and that’s not a happy thing.

With the weather and the use of heater here, humidity is really not an issue.  I don’t really bother with putting any water in here either — I just let it sit naturally.  I rarely open the cupboard either.  I suppose I’ll have to see how this turns out.  I remember when I was in Beijing, I put a few bowls of water in there, and after doing that you can smell the tea more — moisture does have something to do with that.  I might try experimenting with that again sometime soon.

Pumidors

May 14, 2009 · 6 Comments

As I think I’ve mentioned a few times before, I am writing a column for a tea magazine in China, especially on issues of cross-cultural tea habits.  I was thinking about writing on the topic of pumidors (puerh humidors) — a rather unique American thing, I think, especially when you are talking about elaborate setups.  I am interested in what people have done, and would appreciate if anybody can volunteer a picture or two of their creation.  Please leave a comment if you have something to share.  Thanks

Drinking storage

January 30, 2009 · 6 Comments

I remember when I first started out drinking tea and learning about it, a very knowledgeable friend told me that puerh (by which is meant aged puerh — new tea was not in the discussion) tastes best BEGINNING with the 5th infusions. Note that we are talking the BEGINNING of the good tasting part is the fifth infusion onward, going to 10th, 15th, etc. Everything before was not very good, and in fact, the friend rinses two or three times sometimes for older tea, and throwing those away or using them to help age pots.

I think most people, having been raised on the “infuse and throw” culture, will wonder how it could be that a tea can start to taste its best on the fifth infusion. Many I know don’t even necessarily get to the fifth before giving up on a tea.

I think what happens here and what bears repeating is that in the first few infusions, what’s really going into the liquid is what can be called the “storage” taste. Different storage facilities taste different — find two loose traditionally stored puerh, say, from two different stores, and they will taste vastly different. Find two traditionally stored puerhs from the same store, and as long as they have stored both, the first few cups will taste very similar. What happens afterwards is what’s really in the tea — the true taste of the tea, not the storage.

One of the reasons why some people hate traditionally stored tea is the storage taste — it’s not going to go away no matter what you do. If you drink enough infusions though, it does weaken it sufficiently so that you can get to the tea underneath it. The taste is obviously changed, but for better tea, there will be that perfume taste that can be quite obvious in a dry stored tea but less so in a traditionally stored one, but it should still be there.

These days I’ve been drinking my puerh for two days at a time — with the second day being a contiuation of the first. I am using a larger pot with a relatively careless way of brewing them, and they are all traditionally stored, loose or broken tea. While the taste is much stronger on the first day, the second day is often much sweeter and, sometimes, has that nice, sweet quality to it that is ultimately what you’re after.

I’m not saying that that’s the only way to appreciate puerh, but I do think that to focus too much on the first few cups can be very misleading sometimes, especially when it comes to puerh that has been aging for a bit. While it is true that for dry stored tea the effect of storage might be a bit lower, it is still a mitigating factor. What other teas are stored along the cake you’re drinking, for example, will affect the way it tastes/smells the first few cups. That, in turn, can affect your impression of the tea if the first few cups take too much precedence in the taster’s mind.

Aging cakes

July 21, 2008 · 2 Comments

I’m in Portland now, getting ready for the upcoming festivities… so don’t expect much update in the next week or so 🙂

However, there are always observations to be made.  As Walt just pointed out in his comment to my last entry, cakes change — and they are always changing.  I bought a cake of the 2002 Mengku for my cousin a while ago when I was still in Beijing, and now it’s been here for…. 2 years or so.  What I’ve noticed, when I tried it yesterday, it’s much sweeter and mellower than when I got it — less bitter, and more fragrant.  I think the climate here works fairly well for aging puerh — a dry season in the summer, and a wet season during winter.  The wet season here is wet enough so that the cakes are sufficiently moist, and then dries out a bit during the hotter months.  In fact, I suspect the whole Pacific Northwest works fairly well, probably.

I wonder how my cakes in Hong Kong are doing.

Storage is important, I think that’s a point that has been hammered home many, many times by now by a wide variety of people, on or offline.

How important is it, exactly?

I went to the City today, and in the afternoon met up with a few tea friends at The Tea Gallery. Among the teas we had was a side to side comparison of a cake that Michael, the proprietor of the place, that are of the same batch. Except — although it was one batch of tea, some stayed in Hong Kong for an extra three years while the others he brought with him three years earlier to New York.

While we brewed it a little too heavily, so it was rather difficult to swallow, it did, in some ways, accentuate the differences between the two teas. It was immediately obvious that the New York cake brewed a lighter colour, and the leaves of that cake is also of a greener hue, while the Hong Kong one is darker overall. The Hong Kong cake tastes a bit older, especially if you drink it side by side with the New York one, and less green — it has something extra. The three years definitely made an impact.

What was rather interesting was that the last cup, Michael mixed the two — and the tea was actually more interesting, although, it was also weaker, and having endured a number of rather bitter cups, maybe it just wasn’t as strong? I’m sure he’ll be brewing it tomorrow (because the leaves are hardly spent), and I might hear about it again.

Storage issues

June 23, 2008 · 5 Comments

Moving with a lot of tea to a new place means having to worry about where to store them. Oolongs are simple — you just keep them out of light and air tight, and it’s good. All you need are shelves (which I need to acquire). Puerh, on the other hand, is a trickier matter — right now I have all of them in a cardboard box, the same way they came during the move. I have not moved them at all.

The question is whether or not to take them out at all, or if I should store all of them as is. When it comes to storing tea, everybody has a different take on how puerh should be stored. The various theories I’ve heard range from absolutely closed environment, where little air is exchanged and teas should be “kept” so that they retain much of their qi (so the theory goes), to leaving them out in open air and let them air out. The most extreme, as I’ve related on this blog a long time ago, was a lady who bought a whole bunch of cakes from Hong Kong (all suitably wet stored, of course), took them to the desert weather in Xinjiang, put them in a big warehouse with all the doors/windows open and letting the desert wind blow through the cakes in an attempt to “tuicang”, literally “let the storage (flavour) fade”. I was unlucky enough to get to try the end result of this attempt, and it was, well, nasty. It seems like in addition to getting rid of the “storage” smell, much of the tea’s flavours and especially the smoothness also went out the window, carried out, no doubt, by the desert wind.

Ever since having tried that tea I’ve been more inclined to store my teas in relatively closed environments, or at least in places where they don’t see much air circulation. My teas in Hong Kong are stashed on the top shelves of a bookcase, in a corner where little air is exchanged while still being open to the room. In humid environments like Hong Kong or Taiwan, it’s probably best to leave the teas off the floor or even anywhere close to the floor, because moisture seems to be higher there — a cake of mine that I left in the open air in Taiwan on a low coffee table started growing stuff on it after a week of rain…. and I was living on the 8th floor.

What I haven’t decided is whether or not to keep the cakes in the box. I used to think that cardboard boxes probably give off a bit of a cardboard smell, which is no good, but then, most tea merchants keep their teas in cardboard boxes… so does it really matter? Will we notice? I think it’s probably more noticeable in a dry stored tea, because off notes will be more obvious here. Wet stored teas are so dominated by the storage taste that subtle aromatics like cardboard smell probably won’t be very obvious — or who knows, maybe even add to the enjoyment of the tea.

When I was in Ohio I had no need whatsoever of adding moisture — living basically in the woods, I found the soil and flora nearby kept the apartment suitably humid without excessive moisture. After rains it would get wet for a few days, but will slowly dry out. I think the soil, grass, and tress around acted as a sort of buffer that kept humidity more constant within the house. In a more city-like environment though, I think the dynamics are a little different, especially since I now live on the second floor. It’s been raining a lot, but I think in the winter it won’t be too humid, at least not with the heater on all the time. That’s something I have to consider.

I have, however, been able to smell the tea recently just sitting at my desk. Smell, I’ve found, is probably a decent indicator of whether or not a cake is too dry. When I bought new cakes in Beijing they were almost all invariably odorless — you can hardly smell anything. After a few days in my tea closet in Beijing, they would start giving off some aroma. The difference was obvious, and since in places like Hong Kong a puerh cake is readily detectable by a human nose, I take that as a good sign.

So, lots of unknowns…. but I think I am going to stick my cakes on the top shelf in the closet, and possibly leave them in the cardboard box this time to see if anything happens.

Traditional storage

May 28, 2008 · 4 Comments

One of the topics that came up during Sherab’s visit on Saturday was traditional storage. Traditional storage is sometimes viewed with mythical vile — it’s bad, it’s awful, don’t do it, it’ll kill you, etc. I’ve heard versions of all that.

I think slowly, people have come to realize that there are two kinds of traditional storage, so to speak — good and bad. Good traditional storage can produce great results — witness all the “classic” puerh cakes from the 50s onward, most of which received some traditional storage treatment at some point in their life. Others can be incredibly bad — cakes that are moldy inside out, growing not only the usual (and all together ok) white stuff, but also yellow, red, black… you name it. The first kind is welcomed, the second should be avoided.

I think Cloud at some point or another wrote a few things for the Puerh Teapot magazine (Chinese version) that talks about traditional storage. I am not sure, but I don’t think they’ve been worked into English through the Art of Tea. I suspect, though, that it will be a useful exercise. Essentially (and this is also from my friends who are more knowledgable about this sort of thing than me) what happens is traditional storage is only one phase — usually not a very long one — of a cake’s storage life. It should not stay permanently in a “traditional” storage condition, which generally means high humidity and often accompanied by higher heat. After that, however, the cakes should be aired out and left alone in drier climes — storage units that are ventilated and not in the basement of buildings. Much of an aged tea’s life is actually spent in such storage units, not traditional basements.

Also, traditional does not imply spraying water all around or anything like that. In fact, sometimes it might even be necessary to control the humidity by putting things that will absorb moisture (I believe chalk is used — spread around the floor, although my memory is fuzzy on this). The cakes that are stored in traditional storage should never touch the floor, the walls, or anything other than each other, really — they’re put on racks so avoiding the very damp floor and they’re usually placed a little away from the walls to avoid condensation, etc. You don’t want them THAT traditional.

Ideally, teas that were traditional stored should spend time outside of that storage to age, and to also let the “traditional storage” flavour go away a bit. It will never entirely disappear, but it does dissipate over time. I drank some traditionally stored loose puerh today that has mellowed considerably comparing to when I first got it some two or three years ago. It is now quite drinkable, smooth, without any sort of nasty mustiness, and most importantly, it can be rebrewed many times (I think I drank around 20 today). Cooked puerh will be lucky to last 7.

So if you got some stuff that smells musty and looks a bit nasty, don’t give up on it and say it’s bad and throw it away (again, this only applies to stuff with white dusting on it — yellow, red, or really any other colour mould should be avoided). Give it time, let it air out, and after a few years, it might surprise you.

Wet stored tieguanyin

May 5, 2008 · Leave a Comment

This is a tea that I’ve talked about a few times before, a “wet stored” tieguanyin from my favourite candy store in Taipei. I believe it is around 25 years, from what I was told, but it’s hard to say for sure, for there’s no real proof of anything.

It is, I think, one of my better finds. I’ve sent a few samples to various people, with varying comments. The usual one, however, is that it tastes like aged puerh.

I don’t really know how the aged puerh taste got in there. I theorize it is the fact that the tea got slightly mouldy (you can smell it a little when it’s in its original big bag — a musty smell). The mould helped change the taste of the tea so that it has acquired a bit of that uerh taste.

It looks the part too, at least to the untrained eye.

Yet the tea is not puerh if you drink it carefully, because there are floral notes you’ll never find in a puerh. If puerh tastes earthy, this tea is more of a punchy floral note. It’s not fruity like the non-reroasted aged oolongs. They’re very different beasts.

The tea will last longer than you have the stomach for it. It might get boring in a way, but personally, I like teas that keep giving me many infusions of sweet water, hours after I first started. My requirements for a good tea isn’t very high.
