Notes

Special Instructions / Notes:
WARNING: this recipe assumes that you have an oxygen system and are able to add sugars and oxygen to the beer during the first 5 days of fermentation.

A few extra bits of information that you might find useful:
Est. pre-boil gravity, before adding malt extract: 1.058
Est. pre-boil, after adding the malt extract: 1.096
Est. original gravity, before adding all the sugars: 1.108
Est. original gravity, after adding all the sugars: 1.146
FG: 1.015
Abv: 17.8%

Ferment at 62F
Once primary fermentation starts, say 12-36 hours after pitching, do the following:
Feed sugars twice a day if possible (see schedule below).
Every time you feed, inject oxygen.
Sugar mix: in a sauce pan, mix 1/4 cup of water with maple syrup, brown sugar, table sugar and the yeast nutrient. Heat and stir till the sugar is mostly dissolved. Don't worry about cooling it off. Just dump it right in.

Feeding schedule:
(WARNING: in the Extra Ingredients section, the numbers were for 40 gallons. Since you will most likely be fermenting this in increments of 5 gallons, the numbers below are for a 5 gallon batch).
Day 1, 1: 1/4 lbs total of brown and table sugar, 1/2 maple syrup, 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate.
Day 1, 2: 1/4 lbs total of brown and table sugar, 1/2 maple syrup, 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate. Note that by that time you should have your WLP099 yeast starter going.
Day 2, 1: 1/4 lbs total of brown and table sugar, 1/2 maple syrup. 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate.
Day 2, 2: 1/4 lbs total of brown and table sugar, 1/2 maple syrup. 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate.
Day 3, 1: 1/4 lbs total of brown and table sugar, 1/2 maple syrup. 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate.
Day 3, 2: 1/4 lbs total of brown and table sugar, 1/2 maple syrup. 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate. Pitch the WLP099 yeast!
Day 4, 1: 1/4 lbs total of brown and table sugar, remainder of the maple syrup. 1/8 to 1/4 teaspoon of yeast nutrient. Oxygenate.
Day 4, 2: 1/4 lbs total of brown and table sugar. Oxygenate.
