Ok so like most great products of the past there are slight variations in the potency of the ginger. However, when you factor the environmental reprucussions of farming ( tilling) the land and the seemingly lack of concern by most towards the consequences, this is a great drink. As for the Dutchess review concerning health adversities she experienced, I can only advise that you keep in mind that carbonated beverages in general are to be moderated. Canada Dry Ginger ale & Schweppes are two really good products. When consuming drinks like these please remember that your own personal health history and or current state plays an important part in how it will make you feel. In other words do not expect Advil or Tylenolic effects from any of these products. I really like that I can enjoy a good ginger drink especially knowing that I am unable to grow it. Thanks always my Canada for always being environmentally correct.
