I think the almond flavour might be what’s responsible for the sweetness of the tea – it’s covering up the astringency you’d normally get from any kind of citrus fruit. The mix of spices in the tea really ‘goes’ with the citrus flavour – they’re strong enough to be noticed, but not so strong that they take over the entire tea.
This isn’t a very robust, but it’s light and easy-drinking, so I think it’d be nice as an afternoon or after-supper tea to sip.
