An insulated drink bottle keeps whatever you filled it with — water, tea, coffee, juice — at the temperature you filled it at, for hours. Food-grade stainless steel is non-reactive so any drink is safe; BIS IS 17526:2021 certification verifies the insulation actually works.
Key Facts
- Food-grade steel is non-reactive with any drink — water, tea, coffee, juice, milk.
- The vacuum keeps the temperature stable regardless of contents.
- HYV bottles are BIS certified to IS 17526:2021, India’s national standard for stainless steel vacuum insulated bottles.
- Clean between different-flavoured drinks to avoid taste transfer.
- HYV uses food-grade 304 stainless steel with double-wall vacuum insulation for verified hot/cold retention.
Any drink, any temperature
The steel doesn’t react. The vacuum doesn’t care. Water at 5°C, coffee at 85°C, juice at ambient — the bottle handles all of them.
When to clean between drinks
Coffee → water: clean, or you taste coffee for days. Water → tea: usually fine. Milk-based drinks: always clean thoroughly to avoid smell.
