To make real ginger beer you need a GBP (ginger beer plant), a real one not a feed yeast variety. I enjoy ginger and use it daily at the restaurant, grating it on the fine side of a box grater and then squezzing out the juice, i dont like the grainy texture of grated ginger in my fnished dishes. I think ginger flavored beer sounds awesome and plan to add some to a re-brew of my placer county mandarin orange ipa that came out great, albiet a bit powerful, but with a hint of ginger heat and sweet, could be even better.
