Nilgiri Iced Tea

Cold-brewed Nilgiri orthodox tea from the Blue Mountains of Tamil Nadu: the one Indian black tea whose natural clarity holds when chilled, its bright amber liquor poured over ice with a long strip of fresh lemon peel and a single sprig of mint

Origin: Nilgiri Hills, Tamil Nadu, India

From the journey of Tea.

The Nilgiri Hills produce a black tea with a quality unique among Indian varieties: a naturally bright, clear liquor that does not cloud when cooled. Most black teas contain high levels of tannin-caffeine complexes that precipitate out of solution at lower temperatures, turning the liquid opaque and murky — a phenomenon called 'creaming down' in the tea trade. Nilgiri teas, grown at altitude in the cool mist of the Blue Mountains, have a tannin structure that behaves differently: the liquor remains transparent and bright gold-amber when chilled, making it the natural choice for iced tea preparations where appearance matters as much as flavour. The character of a properly made Nilgiri iced tea is quite distinct from American sweet tea or the sugared iced tea of hotel lobbies: it is clean, slightly astringent, gently aromatic with a faint floral note, and deeply refreshing without being sweet. It is, essentially, the flavour of the tea itself unobscured, presented in the form that best suits the climate it was grown in. The estates of the Nilgiris: Thiashola, Havukal, Glendale, Chamraj, Kairbetta: produce both orthodox (whole-leaf) and CTC (cut, tear, curl) teas; the orthodox variety, in which the leaf is rolled and withered by hand or traditional machinery, is what should be used here: it produces the clean liquor and delicate flavour that distinguish Nilgiri tea from the robust, malty CTC grades. This recipe uses cold brewing, which extracts the aromatic compounds of the tea while minimising the tannin extraction that hot water accelerates, producing the clearest, most delicate cup.

Ingredients

Tea

4 tsp Nilgiri orthodox loose-leaf black tea (whole-leaf or broken-leaf grade; look for 'Nilgiri FTGFOP1' or 'Nilgiri BOP' grades from reputable specialty tea suppliers; avoid CTC Nilgiri for this preparation)

Water

1 litre cold filtered or mineral water (for cold brew) or freshly boiled water (for hot brew method)

Service

ice, generously, for serving
1 lemon, cut into long thin strips of peel (the yellow zest only, avoiding the white pith) or thin rounds, for each glass
fresh mint sprigs, for garnish (optional)

Optional

jaggery syrup or honey, to taste if sweetening (dissolve 2 tbsp jaggery or honey in 2 tbsp hot water, cool)

Method

Cold brew method (preferred): Place the Nilgiri tea leaves in a clean glass jug or pitcher. Pour over 1 litre of cold filtered water. Stir gently. Cover the jug with cling film or a lid and place in the refrigerator for 8 hours or overnight.
Strain the cold-brewed tea through a fine-mesh sieve into a second jug, pressing the leaves gently to extract all the liquid. The tea should be a clear, bright amber-gold, like pale topaz: this clarity is the hallmark of Nilgiri tea and what distinguishes it from teas that cloud when cold.
Hot brew method (for immediate preparation): Brew the tea in just-boiled water at 90–95°C for 3–4 minutes. Strain immediately and add a large tray of ice cubes to the still-hot tea to chill it rapidly, which helps preserve brightness. Do not allow it to cool slowly at room temperature, which increases cloudiness.
To serve: fill tall glasses with ice. Pour the cold tea over the ice, filling each glass to about 3 cm from the top. Add a long strip of lemon peel to each glass, twisting it over the surface first to release the citrus oils.
Add a sprig of fresh mint if using. If you wish to sweeten, add a small amount of jaggery syrup or honey to taste: a very light sweetening that does not mask the tea is appropriate. Serve immediately.

Notes

Nilgiri orthodox tea is available from specialist tea merchants in India, the UK, Australia, and online. Look for estates by name: Thiashola, Glendale, and Chamraj are among the most respected. The designation FTGFOP1 (Finest Tippy Golden Flowery Orange Pekoe, First Grade) indicates whole-leaf, highest-quality orthodox processing with a proportion of golden tips; this grade produces the finest iced tea. Nilgiri tea of this quality makes an outstanding plain iced tea and also pairs beautifully with stone fruits: a few slices of fresh peach or nectarine in the jug during the cold brew produces an extraordinary summer drink.
