I have been making ginger beers in small (1 gal) batches for a while now, using different amounts of fresh and powdered ginger, sugars, yeasts, and brewing schedules. I have just sampled the most recent iteration and it's damn tasty so I thought I'd share.
approx 4" thinly sliced ginger root
1lb brown sugar
1 tsp Cascade hop pellets
1 tsp ground ginger
Cote des Blancs yeast (gave a much better finish than the beer yeasts I have tried)
put ginger in a quart of water over low heat for 15-20 minutes (you are essentially making a ginger tea)
add sugar, stir to dissolve and bring to a boil
add hops and powdered ginger
boil 5 minutes
remove from heat, dilute to 1 gallon, pitch yeast when temp is appropriate.
I made this on 1/27. OG = 1.044, Today (2/17) FG = 1.004
This one has a great ginger taste, though without the direct heat of fresh ginger. Just enough sweetness left and slightly effervescent.
I will have to keg, chill, and tell you more, but this one is great so far! Maybe some ginger added to the keg (like a dry hopping) could raise the heat...

This seemed like the best thread to pull for this, but please mods feel free to break out if necessary into a separate thread.
I've been playing with a similar ginger beer recipe to the one above, with some slight variations. Here's my current (5 gallon) recipe for my organic, gluten free ginger beer with Champagne Yeast:
1. Mix 3 lbs high quality ginger into 2.5 gallons water
2. Add 10 cups turbinado sugar, or 8 turb, 2 brown sugar. Generally, 2 cups/gallon is mildly sweet.
3. Add 1 tsp cream of tartar, 1/4 tsp of cayenne pepper, pinches of sea salt and other spices
4. Boil all that for 15 minutes, then cool for 120. Strain, transfer to fermenter, double the water, and add 1 cup each of lemon and lime juice. Add yeast when temp is right (I shoot for 101). Usually OG is around 1.044 here.
5. Ferment for 48 hours (stirring regularly) for "Ginger Ale" at around 1.3% ABV, or 96 hours for about 3.3%. I haven't yet tried to fully ferment and add priming sugar yet. Alcoholic potency isn't my primary goal. 3.3 sessionable is.
6. Bottle to carbonate, and refrigerate when plastic bottles are rock hard (24-48 hours, depending on temp and amount of yeast in bottles).
I'm at the point where I'm pretty happy with this baseline recipe, and want to start mixing it up with variations of yeasts and hops. Does anyone have experience or advice about which combos might work best with this type of brew? Sounds like cotes des blancs yeast and Cascade hops mentioned above worked well. I'm quite happy with it in its current form, but would like to see where else I can take this recipe. Those two sound like a good jumping off point.
Also, I'm happy to answer any questions someone else might have on ginger beer making. Doesn't seem like there is a vast wealth of knowledge out there about ginger beer, at least relative to the amount of knowledge out there about regular beers. I've had about 13 passes at getting to that idealized batch and have learned some good lessons along the way. Thanks!
