Is Nevisan tea organic and chemical-free?

Yes. Every batch is PGS-India organic certified and grown without pesticides or chemicals. From soil to seal, completely chemical-free.

Can Nevisan whole-leaf tea be steeped more than once?

Absolutely. Because Nevisan uses 100% whole-leaf tea, most varieties can be steeped twice — the second cup is just as rewarding as the first.

What is the shelf life of Nevisan tea?

All Nevisan teas have a shelf life of 18 months (use within 3 months of opening) from date of manufacture when stored in a cool, dry place away from direct sunlight.

Where is Nevisan tea grown?

All Nevisan teas are single-origin — sourced exclusively from a single garden in Golaghat, Assam, one of India's most prized tea-growing regions.

Do you offer bulk or wholesale tea orders?

Yes. For bulk orders for hotels, cafes, offices or gifting, contact us on WhatsApp at +91 98642 45687. Minimum order is 20–30 packs of 50gm.

What is blue butterfly pea flower tea?

Blue butterfly pea flower tea is made from the dried petals of Clitoria ternatea. It brews a vivid cobalt blue and is rich in anthocyanin antioxidants. Adding lemon juice turns it purple — a pH reaction. Nevisan's Blue Flower Green blends these petals with whole-leaf Assam green tea.

Is spearmint tea good for PCOS?

Clinical research published in Phytotherapy Research found that two cups of spearmint tea daily reduced free testosterone levels in women with PCOS. Spearmint may inhibit 5-alpha reductase, the enzyme that converts testosterone to its more potent form. Nevisan's Spearmint Green combines whole-leaf spearmint with Assam green tea.

What are the benefits of tulsi green tea?

Tulsi (holy basil) is an adaptogen used in Ayurvedic medicine for 3,000 years. Research shows it can reduce cortisol, support immune function, and improve cognitive performance under stress. Combined with green tea's L-theanine and antioxidants, tulsi green tea supports calm, sustained focus without sedation. [Source: Cohen MM, Tulsi - Ocimum sanctum: A herb for all reasons. J Ayurveda Integr Med. 2014;5(4):251-259. doi: 10.4103/0975-9476.146502]

What is GABA oolong tea and what is it good for?

GABA oolong is made by processing tea leaves in a nitrogen-rich, oxygen-free environment, dramatically increasing GABA content. GABA is the brain's main calming neurotransmitter. Regular consumption is associated with reduced anxiety, better sleep quality, and lower blood pressure. Unlike chamomile, GABA tea allows calm without drowsiness. [Source: Abdou AM et al., Effect of gamma-aminobutyric acid (GABA) administration on stress and fatigue in humans undergoing a problem-solving task. Biosci Biotechnol Biochem. 2006;70(4):901-6. doi: 10.1271/bbb.60464]

What temperature should I brew green tea at?

Brew green tea between 75°C and 85°C — never boiling water, which makes green tea bitter. Steep for 2 to 3 minutes for the first cup. Nevisan whole-leaf teas can be steeped two to three times: rest the leaves 60 seconds between steeps and add fresh hot water at the same temperature.

How much caffeine is in green tea compared to coffee?

Green tea contains 20–50mg of caffeine per cup versus 80–120mg in coffee. More importantly, green tea contains L-theanine, an amino acid that moderates caffeine's effect — producing calm focus rather than the jitteriness coffee can cause. Most people experience no crash after green tea.

Is Assam green tea different from Darjeeling green tea?

Yes. Assam green tea is bolder, with more body and a malty undertone, due to the Brahmaputra valley soil and high humidity of regions like Golaghat. Darjeeling green tea is lighter, more floral, and more delicate. Nevisan teas come exclusively from Golaghat, Assam — known for exceptional whole-leaf quality.

How do I know if green tea is real and high quality?

Real whole-leaf green tea looks like actual leaves — rolled, twisted, or flat but visibly leaf-like. It should smell grassy and fresh, not artificial. It should brew light gold or green, not dark brown. Check that the brand specifies a single-origin (garden and region), not just 'premium Himalayan tea'. Nevisan discloses its Golaghat garden and tests every batch for pesticide residues.

Does chamomile green tea help with sleep?

Chamomile contains apigenin, a flavonoid that binds to GABA receptors in the brain, producing a mild calming effect. Research supports chamomile for reducing mild anxiety and improving sleep quality. When blended with green tea at low brewing temperatures, you get chamomile's calming properties alongside green tea antioxidants with minimal caffeine.

J Altern Complement Med. 2011;17(9):857-63. doi: 10.1089/acm.2010.0318]
