This one is easy... really easy. and oh so tasty

4.5 gallons Treetop apple juice
4 16 ounce cans Applejuice concentrate (primary)
1 16 ounce can Apple concentrate (bottle carb)
2 teaspoons yeast nutrient
1 packet red star montrachet yeast

Add the 4.5 gallons of applejuice to your carboy
warm the 4 cans of concentrate up to room temprature
add the 2 teaspoons of nutrient
stir well

pitch your Montrachet and pop an airlock on there - isolate from air with cheap rotgut vodka.

ferment in primary only for 2 months exactly.

on bottling day, warm the last 16 ounce can of concentrate to room temp and pour it into your 5 gallon racking bucket, carefully rack off Cider from your carboy into this bottling bucket, take care not to splash or it'll cause oxidation, make sure your flow creates a bit of vortex (NO SPLASH!!) to mix in the concentrate.
now...bottle this nectar of the gods.

you should have good carbonation in 2 weeks - the brew is ready to drink then or put some age on it (cannot vouch for aging - My batch is two and a half months old today, just cracked my first one after Carbing and it is supurb.)

Flavor is very Appley, dry and tart (but not unpleasantly so).

cannot list gravities of this (I fly by the seat of my pants) nor can I acurately give an ABV. If any of you pros out there try this one - I'd love to get a run down by the numbers just for my notes. please PM me
