G'day Bertie,
If you have a kit that usually does 20 litres, but have only added 10
litres of water, I'd say your 1020 is about right for finished.
Think of it like this. The SG of water is 1000 (1). If you add stuff (beer ingredients) to water the SG goes up (in your case to 1036). Fermentation takes place and some of the stuff turns to alcohol which has an SG of less than 1000, thus lowering your SG. With 20 litres of water to start with
your SG might go down to 1010 or something. With only 10 litres the ratio
of stuff to water is higher, so your finished SG should be higher.

My normal beer kit is Coopers Oz lager. You add water + concentrate + sugar >and you get 40 pints.
The Brupak Beers of the World, uses less added water and no sugar and you >get 20 pints. Both Coopers and Brupak state that the finished abv should be >about 5%. If you subtract the starting sg from the final sg (1036 - 1002) >then divide by 7.46, you get 4.5% add on 0.5% for the secondary ferment and >you get 5%.
Therefore, if the Brupak's ssg is 1036 and it's now 1020, (36 - 20 divided >by 7.46) = 2.4% + 0.5% = 2.9%. So this is well short of Brupak's figure of >5%, so it must be stalled. I need to think of a way of unstalling it. >Tomorrow I'll email Brupak, but thanks for your info.
