I'm still struggling to understand how to calculate the alcohol content from the SG of the brew. My cider started at 1.100 and finished at 0.995. The refractometer puts it at about 20% ABV. Is that Close ?
Should I be starting with less sugar as I'm getting a very strong brew. My first try was a lot lower but tasted better.
TC, SG = Alcohol ??

I got a little chart with my Hydrometer that you can use to calculate an SG of 1.1 = 13.2% and an FG of .995 = -0.7% giving an approximate total of 13.9% more like apple wine than cider I wouldnt drink it by the pint or you'll be falling over quickly or you could water down.
Cider I believe should start at between 1.045 and 1.065 giving a potential of between 6% and 8.5% and yes starting with less sugar would help, you can always add some suggar measure the SG and add more in little increments 30 grams per litre should increase the SG by .01 (ish)

To give you some idea, my TCs normally start somewhere in the region of 1.046 and end up at 5-6%.
That's with no additional sugar BTW, just the intrinsic juice sugars.
Even my mental 8%ers only started at 1.060 (250g of Tate and Lyle in addition to intrinsics).

The hydrometer reading is distorted by the presence of the alcohol at the end of fermentation of a high gravity must - you can't just subtract one reading from the other.*
Likesbeer's chart is the way to do it.
EDIT: *At least, if you want to be reasonably accurate.

Racked it off tonight into 2 DJs, tested at a Gravity of 0.995 If that's about where it ends, looks to be about 9.5% abv. Hope it tastes as good as it smellsdeepinvader wrote:OK, done that, 1 litre apple concentrate (makes 8 litres) 1 Kg sugar, made up to 2 gallons, yeast nutrient, pectolase and youngs super yeast. Took a reading of 1.065 and tucked it up in the shed.

Just bottled it, 500ml Shepherd Neeme bottles with a flat teaspoon of sugar. FG was 0.994 which computes to about 10% ABV I believe.deepinvader wrote:OK, done that, 1 litre apple concentrate (makes 8 litres) 1 Kg sugar, made up to 2 gallons, yeast nutrient, pectolase and youngs super yeast.
