As others have already pointed out, you will get better results if you
use a teapot for PG Tips Pyramid bags. If you really want to brew
your tea in a mug, make it a large one because this tea can be quite
strong. You can also buy a "tea bag squeezer", which is basically a
small set of tongs, for removing tagless tea bags from your mug, It's
less messy than a spoon because you can squeeze out all the excess
water, and you can also grab a hold of the bag. With a spoon, the bag
can slide off and fall back into your tea.

PG Tips is also available in string and tag style double-chamber bags,
which are specifically designed for brewing in the mug. This is your
basic Lipton-style tea bag. They are called PG Tips One Cup. They
are a little more expensive than the pyramid bags and a little harder
to find, but are available online from the British Express at
