White tea’s delicate name and pale color might lead you to conclude that it’s the most gentle tea in your stash. For the most part, you’d be right, but there’s an unexpected catch to this tea, one that stumps even veteran tea drinkers. It’s not only low in caffeine… It fluctuate dramatically from plant part-to-cup.
Knowing this shift will affect what time of day you have that last cup of tea and how you brew it. That is the key to all this: Bud-to-leaf ratio. To safeguard delicate young growth against intense sunlight and other pests, plants stores a lot of antioxidant and stimulant compounds in their buds. As they grow out into mature leaves, that density decreases. This is why, for instance, a tea made solely of these young buds (Silver Needle) will pack more of a punch different than one that includes lots of older leaves.
How to Make White Tea Right
The chart above details this by variety. Bud-rich teas like Silver Needle tend to have higher amounts of caffeine then you’d think for something so mild, and the opposite is true for leaf-forward ones. It’s not just because of the way they’re processed; it’s also because of the biological age of plant itself.
The processing do play a part as well, though not nearly as much as you might imagine. White tea isn’t put through many changes. They just dry and wither it (no fermenting or rolling step like oolongs or blacks). This lack of fuss maintain high amounts of EGCG. It is a super-antioxidant. Not using high heat during the early stages of processing keeps those good things right where they are.
And the combination of caffeine plus l-theanine create what is known as a synergistic effect, meaning you recieve a calming sense of focus and support for your cells’ health. In short, it provide no jitters and an alert feeling. That’s what hooks ‘em on it… The soothing, even energy. People come back to it again and again. Day after day.
Temperature: this is your greatest tool of control when it comes to brewing. Scalding the delicate white buds will destroy their floral aromas and release harsh tannins, turning the tea bitter rather than sweet. You need heat but not fire. To allow the flavors to develop gradually, aim for approximately 160 to 170 degrees Fahrenheit for most delicate types.
For whites made from more mature leaves (such as Shou Mei), go a little higher. Closer to 185 degrees. Let the tea steep gently, keeping in mind that white tea is forgiving. Unlike black tea, which becomes bitter quickly, you rarely mess up white tea by leaving the pot on a few extra minutes. These subtleties can also be enjoyed via cold brew.
White tea brewed with cold water over several hours pulls out more of its natural sweet notes and less of the bitter ones. You’ll still taste the caffeine, but it’s mellowed, not up front like it is when hot-steeped, but woven into the flavors instead. It is a good choice if you’re looking for something antioxidant-rich that’s easy to drink while staying hydrated (without having to worry about crashing from too much stimulation later in the afternoon).
Stash properly: Proper storage is key, and you should also keep white tea away from stronger smelling coffees and spices; it will soak up their aroma. Moisture and light are enemies of freshness. When your tea smells like what was on the dinner plate last night, it has done its job poorly. Begin with filtered water so that subtle floral notes (which is what make great white teas worth the money) can come through.
In conclusion, white tea is all about contrasts. It is fragile yet packed with nutritional punch. It is light on the palate but has the potential to deliver a surprising jolt. And when you do it right, treat your water with respect and honor the bud-to-leaf ratio. You open up a drink as comforting as it is complex.
Reach for the floral Silver Needle, or go for something stronger like the Shou Mei, and you’ll be drinking one of the purest examples of tea-growing there is. It is simple, but not if you don’t know what you’re doing.
