Sandalwood, like any natural, does vary from batch to batch. Genuine Indian sandalwood from Santalum album is extremely difficult to obtain now and to be honest probably better not to buy as the plants there are endangered. It certainly should not smell like pine needles.
Personally I use Vanuatu Sandalwood from Santalum austrocaledonicum, which is grown in a sustainable way. It has been out of stock for a while at Hermitage but I believe they will shortly have some available again: I'd recommend trying that.
