This is a pretty good backup to PG Tips. The loose leaf is better than the bags of course, but harder to get in Canada. The tea in the bags is often dust quality tea so you really have to be careful when brewing it not to over steep.
I find Twinings is often overpriced since it’s an import here, but it’s far better than any of the bland supermarket Orange Pekoe/ Ceylon teas that are the alternative in Canada.
And as always with black tea make sure your water is actually boiling when you pour it on for the best flavour!
