I was watching one of the old BBC Agatha Christie "Tommy and Tuppence" stories starring Francesca Annis, and they were drinking "Horse's Necks". In the US, they're usually made with whiskey and ginger ale, but they apparently made them with gin and occasionally referred to them as "GGs". I thought I'd try one, and that got me to thinking if there was a good ginger ale alternative to Canada Dry or Schweppes. I found "Q", and then I came across instructions by Alton Brown for making it yourself with ginger, sugar, yeast and water that seemed pretty easy. Has anyone actually tried making their own? Any advice or hints?
