Flask help

[gungholierthanthou]

Boring thread I know but has anyone found a flask that doesn't make tea taste manky?

I read that tea tastes manly because of the milk in it being kept hot for so long. So you either need to drink it faster or add the milk when you want to drink it.

I bought one from paperchase,drink is leak proof. I normally wouldn't drink from flask, but this one means I can have my hot drink and commute to work with it. Yea now doesn't have a weird taste or smell.
