I need to goto the grocery store tomorrow; if they have any fresh ginger I'm planning to brew a 3 gallon batch of ginger ale Thursday or Friday, with both fresh and powdered ginger to get it really spicy. Just winging it

I'll use citric acid instead of phosphoric or lactic to acidify the mash because I want the citric taste to carry through. Just a little bit of hops for preservative. And I might use a wine yeast that can't ferment complex sugars so it will have more body and maybe even a little sweetness.
If they don't have any ginger I'll have to figure something else out
