Don't let the milk come to a boil since it'll burn the milk. Keep the heat on low.
Add vanilla extract after the milk comes off the heat since you don't want it to cook down and evaporate on the stovetop. The flavor will be weaker if you cook it.
Make sure to hold down the lid of the French press so that you don't make a mess when pumping.
Only fill the French press halfway with the chamomile tea latte since it'll double in volume after pumping the plunger.
Any milk you prefer can be used. But know that not all milk will froth as well as whole or 2% milk.
Loose tea, tea sachets, or tea bags can be used to make this drink but I recommend using loose tea or tea sachets since the quality is a lot better.
When you heat milk, it naturally tastes sweeter so I don't add any sugar or sweetener. If you want to add something sweet, feel free to add a little honey or honey syrup since it goes well with chamomile.
