If you make tea with 2 bags does this mean double the caffeine per cup?

It's not quite as simple as double the caffeine. Here's why:

* Steep Time: The longer you steep tea, the more caffeine extracts. With two tea bags, the water may not be able to extract all the caffeine from both bags in the same time you'd steep one bag.

* Tea Type: The caffeine content varies greatly between tea types. Black tea has more caffeine than green tea, and herbal teas have almost no caffeine.

* Water Temperature and Amount: The amount of water and the temperature you use can also affect caffeine extraction.

So, while using two tea bags *might* increase the caffeine content, it's not guaranteed to be double. It could be a bit more, a bit less, or even about the same depending on other factors.

If you're looking for a stronger caffeine kick, try:

* Using a stronger tea type (like black tea) or a larger amount of tea leaves.

* Steeping your tea for a longer period (but be careful not to over steep and make it bitter).
