I found this on The Bee's Lees (mead site), but this table applies to all. You have to scroll to the bottom to find it, so I pasted it below the link:

Ha! Math is NOT my best feature!! Actually that formula is easy, but I like the chart best because at a glance if you know the % of alcohol you want to come out with, you can be sure your starting SG is one thing and the end is another.

Nice formula!

a similar method

SSG 1090
final SG 995
------
95
divide by 7.36 = 12.9 %, x 7 divide 4 = 22.5 deg proof

You can be sure of your starting sg, but it's difficult to be sure of your final sg.

Final SG, difficult!!, to quote Bob Lockwood "your hydrometer is your friend", you take your initial reading!,record it! on a card attached to the DJ along with the ingredients, date, type, yeast, style, SG!, when ferment is finished and wine has cleared and has been degassed take an SG reading, with a hydrometer!, go back a couple a post's and calculate!!!, if any of you guy's across the pond don't have C.J.J. Berry's book "First Step's in Winemaking", go and buy it!, the recipes are old school and a little sweet/high alc, but are reliable, simply adjust the sugar! down a little!:gn
 
Ct,?, does one mean County?, Julie my bird!, you are close! but not quite right , Cornwall is a Duchy!, and we consider ourselves to be seperate from England(Land of the Angles), we are Celt's and proud of it!, like the Amish! we say "be careful amongst them English"!, happy brewing my 'ansome's, all th' best Bear, H.
