SAPPHIRE Tea Set: Butterfly Infusion, Double Walled Cup & Round Infuser

The deep blue colour comes from anthocyanins — pH-sensitive natural pigments in the butterfly pea flower. At neutral pH the tea brews a rich, vivid blue. Add something acidic — a squeeze of lemon, lime, or a splash of hibiscus tea — and the pH drops, triggering an immediate shift from blue to purple or violet. The colour change is instant and complete, which makes it spectacular to watch, especially through the transparent double-walled glass of the Sapphire cup. The same anthocyanins responsible for the colour change are also the compounds behind butterfly pea tea's antioxidant and wellness properties.

Butterfly pea flowers are rich in anthocyanins and flavonoids — powerful antioxidants linked to supporting cognitive function and memory, promoting skin health and hair thickness by protecting against oxidative stress, supporting eye health, reducing inflammation, and having a mild calming effect on the nervous system. In Ayurveda it is classified as a medhya rasayana — a herb that supports intelligence and mental clarity. It is completely caffeine-free and naturally free from artificial colouring — the vivid blue is entirely from the flowers themselves, which is why the Sapphire Set's transparent double-walled cup makes the colour so visually striking.

A double-walled glass cup is made from two concentric glass layers with an air gap between them — similar in principle to a thermos flask, but in transparent glass. The air gap acts as insulation in both directions: it keeps hot drinks hot for longer without heating the outer surface of the cup (so you can hold it comfortably), and it keeps cold drinks cold without the cup sweating or forming condensation on the outside. For butterfly pea tea specifically, this means the vivid blue colour stays visually clear and undistorted through the glass while the drink maintains its temperature — a combination that a standard mug or ceramic cup cannot offer.

Fill the round infuser with approximately one heaped teaspoon (2g) of dried butterfly pea flowers. Place the infuser inside the double-walled cup. Pour 180–200ml of water heated to 90–95°C over the infuser — the water will begin turning blue almost immediately. Steep for 3 to 5 minutes for a rich, deep blue. Remove the infuser. At this point you can drink it as is for a clean, mildly earthy floral tea, or add a squeeze of lemon to trigger the colour shift to purple or violet. For iced butterfly pea tea, brew double strength with less water, remove the infuser, add ice directly to the double-walled cup, and then add lemon for the most dramatic colour-change effect.

Both sets use the same butterfly pea flower infusion and deliver the same colour-changing tea experience, but they differ in teaware format. Nectar pairs the butterfly pea tin with a single 400ml borosilicate glass mug that has a built-in integrated infuser basket — one unified piece of equipment for steeping and drinking. Sapphire pairs the butterfly pea tin with a separate double-walled glass cup and a round infuser — two distinct pieces that offer the advantage of the double-walled cup's superior heat and cold retention. Choose Nectar for the convenience of a single vessel; choose Sapphire for better temperature retention and a more premium cup.

It is one of the most visually impressive gifts in the entire Chayam range, specifically because the colour-change moment — blue shifting to purple with a squeeze of lemon — happens through the transparent double-walled glass cup in a way that is genuinely striking. Most people who receive it have never seen a colour-changing tea before, which makes the first experience memorable rather than ordinary. The three-component set — tin, cup, and infuser — also feels complete and considered as a gift rather than a single product. At ₹795 it sits at a price point that works well for birthdays, housewarming gifts, and occasions where you want something visually distinctive rather than just practical.

Yes — for most healthy adults one to two cups daily is safe and well-tolerated. Butterfly pea has been consumed regularly in traditional medicine across India and Southeast Asia for centuries. It is completely caffeine-free, making it suitable at any time of day including evenings. People with known allergies to legumes — butterfly pea is part of the legume family — should consult their doctor before regular consumption. It is not recommended during pregnancy as its effects on uterine contractions have not been sufficiently studied. For most people it is one of the safest and most enjoyable daily wellness teas available.
