Ruiz swears by ice brewing also known as kouridashi-style brewing , a Japanese method of frigid cold water extraction. With this technique, the tea brews as a big block of ice melts. The method: Start with a rocks glass. Put a big ice cube at the bottom the kind of oversized cubes you might see in a fancy whiskey rocks at a nice cocktail bar and drizzle a few drops of water on the ice cube to trigger the melting.
If you level up and want to try your hand at fruity flavors in your iced tea, try making an infused syrup, like this plum concoction in our cold brew plum iced tea. The leaves: Kouridashi is best utilized for really special tea leaves, such as super seasonal green shincha, gyokuro , or Bao Zhong oolong. The math: Drop between one and two teaspoons of tea leaves into the cup on top, next to, underneath—it doesn't matter and let it go for 20 to 30 minutes. It'll be melted enough so that you have a small volume of really awesome iced tea.
Also re-steep if you have a lot of extra time on your hands and are thirsty for more tea. Add between one to two teaspoons of tea leaves, and let that steep for about six minutes. Especially larger molecules like proteins or even some smaller molecules like tannic acid will not get extracted from the tea leaves easily when using cold water. These require hot or boiling water. Of course, this can have both a positive and a negative impact on the tea you brew.
But more often than not, tea bags are produced to be infused at precise temperatures for a set amount of time. Tea inside tea bags is more often than not fanning or dust, which are powdered tea leaves. Because of this, the tea leaves have a large surface area and will infuse quickly.
Manufacturers exploit this mechanic and use a minimal amount of tea per tea bag that only works well when brewing with hot water for a set amount of time. You would need more tea and, ideally, loose leaf tea for the best results for brewing with cold water.
For example, Darjeeling black tea in a regular tea bag will infuse well when brewing with boiling water for minutes. With cold water, you get close to no flavor at all. Cold water is not able to extract as much caffeine, catechin, polyphenols, proteins, flavonoids from the tea leaves. The amount that can be extracted is very dependent on the water temperature. This is due to the solubility of most compounds increasing exponentially with the temperature.
It is a general rule that compounds are more soluble in hot or boiling water than in cold water. This is due to the fact that liquids are able to hold more molecules in solution at higher temperatures.
What this means for your tea is that some compounds are much less soluble at room temperature or below than they would be when brewing with hot water. There are both positive and negative effects to this. That is because green tea has a lot of bitter compounds that have not been degraded through oxidation to black tea or roasting often found with oolong tea.
Molecules like various proteins, flavonoids, polyphenols, caffeine, catechin and many other compounds are not dissolved easily in water at low temperatures. Other molecules are still soluble quite well at low temperatures.
There is always a trade-off. Withering is a process where the leaves become more flaccid, which leads the membranes of the leaf open up and more permeable. Being permeable means that the leaves lose moisture. Moisture loss is important for the rest of the processing while also increasing shelf-life for the final product.
Withering in itself is quite simply putting the leaves thru some sort of heated air to draw out moisture. The non-Orthodox method for making tea is what is known as the CTC crush-tear-curl.
This is the method that is used when producing larger quantities of tea, like in the production of teabags. Here, the tea leaves get shredded in a machine. This method might be faster, but it cannot be used when making Oolongs and white teas. This is because when shredded, the lea leaves oxidize quicker. Rolling is a process where the flavor literally is pressed out of the tea leaves by wringing out the juices inside the leaves.
During rolling, enzymes and essential oils are being exposed to oxygen. This is the beginning of the oxidation process. In some countries, like the mother country of tea tradition, China, the style and shape of the final tea product can be even more important than the actual flavor.
Luckily, the rolling itself helps preserve the essential oils, which is what gives the tea the sweet aroma it is known for. The CTC process, sadly, destroys the essential aromatic oils and steals away some of the flavors of the tea. Rolling the tea helps preserve the tea for a longer duration of time, which the CTC process also decreases. Loose tea, on the other hand, processed the orthodox way can keep for as long as two years. To work around the fact that the CTC method has this impact on the tea leaves, the tea bag industry has come up with the solution of using whole leaves in bigger bags.
So, if you are looking for a fresh, cold-brewed tea with lots of sweetness and flavor, be sure to buy loose tea. Loose tea brewed with flowers will create a beautiful symphony of aroma and flavor for you and your guests to enjoy. Oxidation is crucial in order to dry and darken the tea. It also increases the smell and flavor of the tea. Some people refer to the oxidation process as fermentation. However, oxidation and fermentation are not the same.
Fermentation is a process commonly used when producing wine or other alcoholic beverages. Oxidation, on the other hand, is what happens with fruit when exposed to oxygen in the air. Rolling the tea leaves speeds up the process of natural decomposition, like a banana turning brown after a while on the counter.
The oxidation has been prevented using heat, which stops the enzymes from decomposing the leaves. White tea is practically unprocessed, and Black Tea, like Oolong Tea, has been through all the steps of orthodox processing.
Fermentation is a completely different process where an absence of oxygen leads to an extraction of energy from carbohydrates. In wine production, the carbohydrates are converted into alcohol using microorganisms like yeast in environments without oxygen. Confusing fermentation with oxidizing is still a common thing when discussing tea production, but now you know the difference.
Now you know a lot about tea. Making tea has been a tradition all over the world for centuries. Drinking tea provides priceless health benefits, and does it with a wonderful fresh taste.
However, loose tea and cold brewing might be more beneficial. Plus, it will take your taste buds to new dimensions. Hey, fellow tea lover! At the time, I didn't drink tea at all.
In fact, I didn't develop a real love for tea until many years later. I have now come to value the worldwide historical and cultural significance of tea, as well as the undeniable health and self-care benefits. Ultimately, I think tea is simply good for the soul. If you used tea sachets or tea bags, simply lift them out. If you made ready to drink cold brew tea add sweetener if desired and pour over ice.
If you made multiple flavors like a fruity herb tea and green tea, mix them together and pour over ice. If you made cold brew tea concentrate , the combination of drinks you can make are as limited as your imagination. You can even look at the Starbucks iced tea menu to see their lineup of delicious iced tea drink combinations.
For instance, they combine tea concentrate with another drink like lemonade or peach juice to create a thirst-quenching iced tea. Furthermore, cold brew tea concentrate is ideal for making iced tea lattes. Finally, to make regular iced tea using concentrate just add fresh water or even seltzer water to make it a little fizzy. A good rule of thumb is to use 1 to 1.
For example, if the package says to make tea using 1 teaspoon per cup of water then use 1 to 1. In other words, to make 8 cups of cold brew tea, combine 8 cups of water with 8 to 12 teaspoons of tea 3 to 4 tablespoons.
To make a strong, concentrated cold brew tea, use 2 to 3 times the amount of tea recommended on the tea package for each cup of water. For example, to make 8 cups of cold brew tea concentrate, combine 8 cups water with 16 to 24 teaspoons of tea 6 to 8 tablespoons. Facebook Pinterest. All it takes to make cold brew iced tea is tea, water and time.
My favorite way to make cold brew tea is with loose leaf tea. Making cold brew tea is as easy as mixing tea and cold water in a jar and steeping it in a refrigerator overnight. Cold brew loose tea minutes after being mixed. Refreshing glass of cold brewed iced tea.
