I have just finished conditioning a Coopers stout to which I added 1 Kg of dark spraymalt when making it up, it finished up at 4%. I have just tried it at 1 month old and I found it to be very thin compared to the all grain version I used to make.
My question is what's the best thing to add, to make it have more body or should I just brew it short. I only want to make it from extracts as I have stopped doing all grain brewing.

There are a lot of factors you can use when brewing AG, but fewer with kits and extracts.  First, Id consider brewing short (less water) - this should increase the malt content, but also by extension, the ABV - you may not want this.  You could also (if you're willing to bend your rules a little) consider a minimash with some wheat malt or oats, which would add body nicely.  Alternatively, addition of non-fermentable maltose will increase the perceived body, so you can add maltodextrin powder to the brew - it's not fermentable, so wont effect the ABV, but will make the brew "maltier" and thicker - I know this works well, and I even use it to add body to turbo ciders [smile] :

What Pinto said, plus you could steep some Carapils. Boil the wort and add to the fermenter. This provides dextrins and would improve the beer by adding things missing from extract. I would brew short too. Maybe 20 litres.

Another option is using a different yeast that attenuates less than the Cooper's. The Muntons standard yeast for example, which is cheap. It would leave more body.

Pinto, you suggest using Maltodextrin, how much would you add to a 20L batch ?, I was thinking about 250g would be about right.

I could make up a no boil mini mash of 250g cut oats, that should give it a better body.

250g is about the amount you'd find in a bag of brew kit enhancer so would be a good start.

One of the Coopers beer enhancers contains maltodextrin.

those coopers stout kits must be one of the most played with kits out there....   loads of variants about that people have made adding treacle and all sorts of stuff, they look perfect for brewing short to 20ltrs and putting in a corny keg.
