I went back to check if Starbucks are still doing the free tasters of Via (in the UK).
Not only are they still doing it; but you can try a blind test against a ground coffee. I preferred the instant. And they give you a '£1 off' voucher for a pack of Via and also voucher for a free tall coffee of your choice on your next visit.
