Sparkling Tea, Made at Home

Tea brewed far too long, cooled and lengthened — where tannin comes from, for the price of a teabag.

Whole leaf tea brewing in a clear glass teapot against a black background, with water pouring in from above.

Time

10 min

Serves

3

Glass

Highball, over ice

Garnish

Lemon twist

Tannin is the thing most drinks without alcohol are missing, and it is sitting in your cupboard. Brew tea much stronger than you would ever drink it, cool it, and lengthen it with something fizzy: what you get has grip and a finish rather than just flavor. This is not the bottled article — the sparkling teas made in Denmark are blended and properly carbonated and are their own thing — but it is the fastest way to understand what tannin does to a drink.

Ingredients

Method

  1. Pour just-boiled water over the tea bags and leave them for eight minutes. That is roughly three times too long, and it is the point — you want the tannin that a normal cup is brewed to avoid.
  2. Take the bags out without squeezing them, and let the tea cool completely. It will taste harsh warm and quite different cold.
  3. Fill a glass with ice cubes. Add 60ml of the cold tea, the simple syrup and the lemon juice, and stir.
  4. Top with sparkling water, poured down the side. Don't stir again.
  5. Twist a strip of lemon peel over the top and drop it in.

Make it yours

Earl Grey

Bergamot and tannin together. The most immediately impressive version and the one to make first for someone else.

Green or jasmine

Lighter and more floral, and it needs less brewing — five minutes rather than eight, or it turns bitter rather than tannic.

Rooibos

No caffeine and a rounder, sweeter body. Good in the evening, and it takes spice well.

Hibiscus

Sharp and deep red. Barely needs the lemon, so cut it in half.

Spice in the brew

A cinnamon stick or three cloves in with the bags. Comes out with them, stays in the tea.

Two dashes of bitters

Tannin and bitterness are different things and they stack rather than compete.

Honey ginger syrup

Instead of the simple syrup. Heat against tannin is an old and very good pairing. Get the honey ginger syrup recipe.

Brew it strong the day before

Cold tea keeps two days in the fridge and gets no worse. Add syrup and lemon to the jug, fizz to the glass.

How to serve & pair

Tall and cold, with more ice than feels sensible. It sits well through a long meal because the tannin gives it something to say after the first mouthful — which is exactly what a glass of soda and cordial runs out of.

Common questions

Why brew the tea so strongly?

Because you are after tannin rather than flavor. Tannin is what gives a drink grip and a finish, and a normal cup is brewed carefully to avoid it. Over-brewed and then cooled, the harshness settles into structure — the same thing that makes a glass of red wine feel like more than fruit juice.

Which tea works best?

A straightforward black tea is the reliable starting point, and Earl Grey is the one that impresses. Green and jasmine want a shorter brew — five minutes rather than eight — because they turn bitter where black tea turns tannic, and those are not the same thing.

Is this the same as bottled sparkling tea?

No, and it is worth being clear about that. The bottled versions are blends of several teas, properly carbonated under pressure and balanced by people who do it for a living. This is one tea, some bubbles and a squeeze of lemon. It is a genuinely good drink and it teaches you what tannin does, which makes the bottled kind easier to appreciate rather than redundant.

Can I carbonate the tea itself?

If you have a home carbonator, yes, and it is closer to the bottled article than topping with soda. Brew it strong, cool it completely first — warm liquid will not hold gas — and carbonate the plain tea rather than the sweetened mix, which foams.
