Coopers

[BeerBelly]

Made a coopers lager kit up last week, it started at 1030 before adding yeast, at around 22 degrees.
Didn't get much of a cake on it just some froth and smaller deposits of cake around the edges of the lager top, it bubbled for about three days continually, then just stopped. It as an aroma of baking bread mixed with a lager type smell.
I checked it today and it read 1000, if my maths is correct thats about 4% or so by volume?
I purposely made the kit slightly short to the 40 pint mark (actually around 34) and added the same amount of sugar as if it was for a 40 pint brew, it looks the right colour, if a little cloudy but that will change i believe :pray:
My question is - is this a little short on alc% or is it there or there abouts?
If so is there anyway to up it or is it a case of keg it wait and enjoy as is.
Thanks.

EDITED TO CHANGE MY CALCULATION :ugeek:

Your calculation is correct :thumb:
4% is about right.
Does your hydrometer read correct ? Those figures seem a little low :wha:
It should read 1.000 in tap water at 20C

Coopers are normally designed to end up around 4.7% ABV when using a kilo of sugar in 23 L, which is about 40 pints. Normally attenuate to about 1008 although I've never measured the OG as I didn't have a hydrometer in my kit n kilo days.

May be an idea to check your hydro. If it's a cheapy one with a paper scale inside sometimes the scale is incorrectly inserted into the instrument on manufacture or has 'slipped' inside the tube. As previous poster says 1000 in plain water.

Yeah it is the 'cheapo' one it came with my complete kit, it does read 1000 in water? Going to transfer to keg today, i bottled 3 litres up last night in two 1.5 litre bottles, just to see if i get any difference between the two methods, (never bottled before)
