Thanks for answering all of my questions. I am going to give this a shot tomorrow.
Nice! Let us know how it goes.
I went and tried both of my hopped ginger brews (with the Cote de Blanc and with the Champagne Yeast) last night after bottling/refrigeration. Not super impressed with the addition of hops (although they taste better with the Cote de Blanc yeast than the CY), but that may be an artifact of fermenting them too dry (5%) as well. Just not a great taste all around. Maybe they'll mellow with time. I'd say for your first batch, stick with my recipe above with Champagne Yeast and you'll be good.
Also, and this may seem obvious but it took me about 5 batches to realize it, splurge on the most expensive ginger you can find at whole foods. It makes a huge difference in the final product. Also, shoot for 2.5% ABV (48-72 hour ferment) for max ginger taste, up to maybe 3.5-4%. Just a couple tips I'd wish I'd received earlier in my experimentation.
