Green Tea Should not be like Buckley’s®

Recently, I came across a social media post about someone that wanted to drink green tea for it’s health benefits, but just couldn’t get over it’s “bad taste”.  I followed the origin of the thread to Reddit, where people guessed whether green tea’s “off taste” for that person may be genetic, like the taste of cilantro. While that can be the case (i.e. genetic sensitivity to a compound called 6-n-propylthiouracil which is found in some flavonoids), others touched on whether it was because the person was making tea using supermarket green tea bags rather than loose tea, whereas a few people hit on the complexity of the issue.  In this post I will discuss some of the factors that affects whether your green tea has a pleasant or “off taste”,  because after all green tea should be something you actually enjoy and not only drink for it’s health benefits.

NOTE: The first part of this article are some personal details of my experience learning to prepare multi-ethnic food and beverages and the second part of the article is specifically about the preparation of green tea and its health benefits.

Once a Foodie, Always a Foodie

I have been adventurous in trying different kinds of food and beverages since I’m little and I remember my parents taking me to an authentic Japanese restaurant even as a kid.  As a teen, I enjoyed cooking multi-ethnic food and learned authentic Cantonese cooking in the 1970s when my mom took a course in Chinatown. In the 1980’s, I learned authentic Thai cooking from the friend of a family business associate who was from Thailand and in those days one couldn’t buy pre-made Thai curry pastes that are available everywhere now, so I sourced the raw ingredients in Lao-Thai groceries and hand-pounded them myself in a mortar and pestle (that I still own and use!). I still have the recipe books sent to me from Thailand.

It didn’t matter whether it was Asian, Middle Eastern or Jamaican, I was a bit of a purist; wanting the ingredients and cooking method to be as authentic as possible. For me, the best way to find out how to make something was to ask someone from that culture that loved to cook.

What was true about food was also true for beverages.

I couldn’t just enjoy a cup of coffee or glass of wine without knowing more. Whether it was the origin of the coffee beans, the length of time the beans were roasted, or how long the water is in contact with the beans — I needed to know, and I was interested in such things when it was not popular either.

Before “West Coast coffee” was a thing and before there ever was Starbucks® or Peet’s, there was a place called La Vieille Europe on St. Laurent Blvd in Montreal which was where I got my single origin, whole bean coffee. As I found out years later, the son of the roaster that owned that store taught the original roaster from Peet’s in the US how to roast beans. Small world.

When I lived in wine country (Sonoma county) of California for a few years in the early 2000s, I was determined to educate my palate to distinguish between different types of wine, which I did. I knew what I liked — which turned out to be an expensive habit when I returned to Canada after 9/11.  At the beginning I explored the wines of Australia and found some I really liked, but missed the delicious and inexpensive  wines of Sonoma and Napa.

Once again, my palate returned to coffee, but finding a decently roasted coffee in Vancouver BC was harder than I thought. Given that this was the “West Coast”, I was discouraged how difficult it was to find good quality Arabica beans that weren’t over roasted. I stumbled across a few small roasters that did an excellent job, but in time they modified their roasts for “local tastes”, so once again, I was back looking for a new roaster. On a few occasions, I ordered from La Vieille Europe in Montreal because in the 40 or 50 years they have been in business, they never lost their passion for properly roasted, single origin coffee.

Over the 20 years I have lived in Vancouver, I discovered the world of quality tea that is largely unknown to most non-Asian born Chinese. There was one excellent tea importer in the Chinatown that I knew of and one that is still in the Richmond Public market that have single origin estate teas that rival the diversity of the best coffee roaster. Over the past 20 years, I’ve explored different types of tea from China and  have come to like a few; my favourite of which is a fermented tea known as Pu-ehr.

A number of years ago, I stumbled across matcha tea in a specialty Japanese store before it was a “thing”.  Knowing nothing about it, I have since found out that I had been using ‘culinary matcha‘ (designed for making Japanese sweets) for drinking.  No wonder it tasted bitter and I needed to blend it with other ingredients to make it palatable. Thankfully, when fresh it had the same health benefits, which I wrote about in 2013 in this article about the Role of Green Tea Powder (Matcha) in Weight and Abdominal Fat Loss. As you’ll read below, I have since learned about making and enjoying real ceremonial-grade matcha, which is intended for drinking from large matcha bowls.

Learning about Japanese Green Tea

At the beginning of this year, I began to explore green teas from Japan when I discovered Hibiki-An, an online tea importer from Uji region of Kyoto. My culinary world expanded once again.

Unable to decide between the many different types and grades of tea that they carry, I order a sampler of 3 types of green teas (Sencha, Gyokuro Superior and Sencha Fukamushi).  They came in 4 oz individual bags — the quantity that can be reasonably be used up within 3 months, when it is fresh.  All 3 teas were all of “superior” grade, which is not the best quality (as my palate is not developed yet) but is a high grade tea.

When the tea arrived, it came with very specific brewing instructions (a summary of the much more detailed instructions on their web page). I’ve since learned that different types of green tea require different water temperatures and different lengths of brewing time.

Wow, who knew?

For the purpose of “cooling” the water to just the right temperature, there is a yuzamashi — which is a small ceramic cup with a spout that the boiled water gets poured into to cool momentarily before being poured into the kyuzu; a special tea pot with a single handle, built in mesh filter and large opening for the water (see photo, above).

You don’t need the get fancy, though.  I had these things for years from my days exploring different regional teas, but one can use an ordinary bowl to cool the water and any plain ceramic tea pot to brew the tea in!

Tea to Water Ratio, Water Temperature and Steeping Time

Each type of green tea has a very specific ratio of green tea leaves to water, and very specific water temperatures and steeping time.

For example, of the three teas in my sample set, Sencha is brewed at 80° Celsius (176 ° Fahrenheit) for one minute, Gyokuro is brewed at 60-70 ° Celicus (140-158° Fahrenheit) for 1 -1/2 to 2 minutes and Sencha Fukamushi is brewed at the same temperature as regular Sencha, but for only 40-45 seconds.

I’ve discovered that following these guidelines using good quality, fresh tea leaves makes a cup of tea that is like nothing I’ve tasted anywhere before. It is not simply snobbery, but the science of what makes for a good cup of tea.

Note: I downloaded several studies that have researched the difference in brewing time, water to tea leaf ratio and water temperature but have decided against boring anyone with the details.

Recently, I became ready to move onto “realmatcha tea and ordered some from the same supplier in Japan.

It came in tiny cans (quantities that should be used up in a 3 week period).

The colour was a bright jade green and the taste had no hint of bitterness whatsoever!

It tastes amazing!

My teas ordered from Japan are my “weekend teas” and during the week I used run-of-the-mill Sencha purchased locally at a Japanese store.

I drink them because I like them and for the health benefits.

Health Benefits of Green Tea

The health benefits of green tea are many. Several large-scale population studies have linked increased green tea consumption with significant reductions in the symptoms of metabolic syndrome; a cluster of clinical symptoms which include insulin resistance and hyperinsulinemia (high levels of circulating insulin), Type 2 Diabetes, high blood pressure, and cardiovascular disease including coronary heart disease and atherosclerosis.

Catechins make up ~ 30% of green tea’s dry weight, of which 60–80% are catechins. Oolong and black tea which are produced from partially fermented or completely fermented tea leaves contains approximately half the catechin content of green tea. 

It is believed that epigallocatechin gallate (EGCG) which is the most abundant catechin in green tea actually mimics the action of insulin, which has positive health effects for people with insulin resistance or Type 2 Diabetes [Kao et al].

EGCG also lowers blood pressure almost as effectively as the ACE-inhibitor drug, Enalapril, having significant implications for people with hypertension (high blood pressure) and cardiovascular disease [Kim et al].

Green tea catechins also have benefit for weight loss. A 2009 meta-analysis of 11 green tea catechin studies found that subjects consuming between 270 to 1200 mg green tea catechins / day (1 – 4 tsp of matcha powder per day) lost an average of 1.31 kg (~ 3 lbs) over 12 weeks with no other dietary or activity changes [Hursel].

Drinking 8-10 cups of green tea per day is enough to increase blood levels of EGCG into a measurably significant range [Kim et al], but matcha contains  137 times greater concentration of EGCG compared to green tip tea [Weiss et al].

WARNING TO PREGNANT WOMEN While EGCG has also been found to be similar in its effect to etoposide anddoxorubicin, a potent anti-cancer drug used in chemotherapy [Bandele et al], high intake of polyphenolic compounds during pregnancy is suspected to increase risk of neonatal leukemia. Bioflavonoid supplements (including green tea catechins) should not be used by pregnant women [Paolini et al].

Green Tea Shouldn’t Taste Bad!

The reason someone would find green tea has an “off flavor” was because the tea was either not fresh, not of a half-decent quality, was brewed at the wrong temperature or for the wrong length of time. Think about it this way; it all a person ever drank was cheap pre-ground coffee, they might think coffee tasted bad, too.

The fact is, one doesn’t need to order tea from Japan to enjoy a decent cup of green tea! I found the green teas below at a local Japanese grocery store and when brewed properly they are great as everyday tea.

If you aren’t adventurous to explore ethnic markets or time is limited, I can highly recommend the online supplier I mentioned above as having excellent price for the quality of green tea, very good explanations on their web page and quick delivery.

For everyday use, I have a little water cooler (yuzamashi) bowl and small single handed tea pot (kyuzu) so brewing a decent quality sencha green tea (my daily tea of choice) has become second nature, but as I mentioned above, one doesn’t need special equipment to make a decent cup of green tea!  All you need is the  right amount of fresh, good quality tea leaves steeped for the right length of time in hot water that’s at the right temperature. The only thing to keep in mind is that once the package of tea is opened, it needs to be stored in a sealed, airtight, light-proof container and used up within 3 months or sooner.

Making a good cup of green tea is not really much different than brewing a good cup of coffee. To make a good cup of coffee, one needs to consider the country / countries of origin of the beans, the bean roasting time and temperature, the brewing method involved (drip, espresso, French press, etc), the required water temperatures needed for that method, and the different grind of beans and a specific water-to-ground-bean ratio required for that brewing method. It sound’s complicated, but if you a few types of coffee regularly, it’s not hard.

It’s the same with green tea.

In one sense, there is a lot to learn at first to make a good cup of green tea but on the other hand, once you know a few basics and find a green tea or two you really enjoy, the rest is easy!

Tea has amazing health benefits, but unlike the cough medicine Buckley’s®, there is no need to drink tea that “tastes terrible, but it works”!
