Quick Answer
Lemon green tea is a classic bubble tea drink of green tea + lemon syrup + ice, shaken. Per the preparation steps on Tang Sugar’s Lemon Syrup product page: for a 500ml cup, start with 150ml of hot tea and add 30g (light), 45g (half), 60g (regular) or 75g (extra) of syrup; for 700ml, 200ml of tea and 40g, 65g, 80g or 100g of syrup, then fill with ice and shake. Syrup gives stable sweet-tartness and fast service; if you add fresh lemon, beware that peel and seeds easily release bitterness.

Why Is My Lemon Green Tea Bitter?
- Squeezing peel and seeds too hard: the white pith and seeds release bitterness.
- Green tea brewed too long or too hot: the tea itself turns bitter and astringent.
- Tea held too long: flavor deteriorates; see How Long Can Brewed Tea Be Held?
