I'll be doing this kit for the 6th time tomorrow (Xmas Present) once I've bottled the Young's New World Saison that is the FV at the moment. It's very hard to get this kit wrong, (excluding the time Young's put the wrong malt extract in the kit) it has always turned out spot on, it's a very forgiving kit, always have had good attenuation and finished product is always very drinkable. I dry hop once fermentation has finished for 2/3 days at 21ºc then I cold crash to 0.5º for 2 days, batch prime and bottle cold, allowing the bottles to warm up and carbonate, for 2 weeks, I find it can then be drunk straightaway but personally I have found it hits a sweet spot after about 4-6 weeks of cold conditioning, it's usually also crystal clear by this time.
*Eggy/Sulphur smells from the FV/Brew Cupboard are perfectly normal.
Just for added information, the last time I did this kit (it was replacement by Youngs for the Messed up one I had back in the Summer) I replaced the 1KG of Brewing Sugar with 1/2 KG of Beer Enhancer (Coopers #1) just because I had some left over from earlier in the year and I wanted to A) Reduce the ABV a little to make a little more of a session IPA and B) to see if it would improve body and head retention. Normally I would not mess around with this kit as it's pretty much fool proof as I have said, it was Freebie and I need to use the enhancer up, so I thought why not. I bottled in the 18 December, and it came in at just short of 4.5%ABV, I had young crafty bottle on New Years Eve and it was quite good, I've put the other 63 bottles away to condition over January and I am looking forward to drinking it during February.
