The Glow Stack | Hibiscus Rose, Blue Pea and Mango Passion

Mango Passion

Blue Pea

Hibiscus Rose
How to brew it
One rule hot, one trick cold
All three brew the same way, and all three are better over ice than most people expect. The cold method is the one worth learning.
Boiling, covered, five minutes
Whole petals and flowers need full heat and real time. Keep a saucer over the cup so the aromatics stay in it. None of the three turns bitter if you forget it.
Overnight in the fridge
Two bags or two heaped teaspoons in a litre of cold water, straight into the fridge. Cold water never pulls the tannins out, so there is no bitterness at all. Keeps two days.
Add lemon to the Blue Pea
Butterfly pea flower brews a deep blue. A squeeze of lemon or lime turns it violet, then pink, almost instantly. It is the anthocyanins reacting to the acid. Nothing is added.
Cold brew, storage, and the stovetop chai method in full.
The maths
What a cup actually costs
Three pouches sounds like a lot to buy at once. Spread across the cups in the box, a cup costs about what a supermarket tea bag costs and a fraction of what a coffee shop charges. The difference is what is in the bag.
| Compare | The Glow Stack | Coffee shop | Supermarket fruit tea bags |
|---|---|---|---|
| Cost a cup | $0.37 | $3 to $6 | $0.15 to $0.45 |
| What is in it | Whole leaf and whole botanicals | Varies | Usually dust and fannings |
| Where it comes from | Bought direct from Indian gardens | Varies | Auction bought, blended by brokers |
| What you get | Three different teas | One cup | One blend, repeated |
| You pay | $42.04, down from $49.47 | Full price, every time | Varies |
| You keep | $7.43 | Nothing | Nothing |
| If you do not like it | 30 days to tell us | Already drunk | Already opened |
Cost a cup is based on the $42.04 price spread across the cups in this box. Coffee shop and supermarket fruit tea bags figures are typical US ranges and will vary by where you shop.
