I managed to pick up one of these kits today, a bit more expensive than the usual 2 can kits, Â£24.95. But to be honest looking at the contents I think it's worth it. The kit contains 4.7 kilos of extract. A mixture of malt and invert sugar, the mix isn't specified. As well as the big bag of wort there is a packet of dried yeast and 2 packets of hop pellets. The yeast packet seemed much larger than usual, it weighed in at 23g! I also weighed the pakcets of hop pellets, the Summit weighed 29g and the Simcoe 23g. The instructions are pretty good, it advises to aerate the wort at the start and doesn't give an over optimistic quick fermentation time.I'll be adding the hop pellets probably on day 12 out of 14. The instructions recommend 8 to 10 days but possibly up to 14 days for the fermentation. I'll be starting this off in the morning. Hopefully I'll give an up date in a couple of weeks when I bottle the kit.
