Done a 2 can muntons kit the other day and I added 500g spray malt without checking if needed I'm just so used to adding 1kg with the kits I normally do I went ahead and dumped a bag in I'm hoping it will help it or could I have ruined it???any info or similar experience with this situation
It will not do the beer any harm but will make the ABV higher it should also give it more body maybe depending on style just do as normal it will be ok
