I dont normally drink loose tea but in the past I have used one of the 'loose leaf holder' devices that Typhoid mentioned.
When I do I normally use the same thing I use to make coffee with now a days. The name escapes me but you basically put the desired amount of tea in the jug pour the hot water in then on the lid is a plunger with a filter on, which you press down slowly, this brews the tea and seperates the leaves.
Good call on getting PG
my favourite. I usually buy it in tea bags. They make pyramid shaped ones which I find brew a lot better than standard tea bags.
Hope that helps
