Despite a massive thread about Munton's produced kits sticking well above the final gravity that they are supposed to get to, I went ahead and bought a Woodfordes Wherry kit. Mainly because I was in Wilkinsons anyway and they are a few quid cheaper there.
The Wherry kit is a premium, 2 can kit, so no additional fermentables are required.
2009-01-27 Gravity: 1042? Difficult to get a reading, despite trying to scrape the 'scum' to the side of the barrel, the hydrometer seemed to have a magnetic attraction to it. I think the bottom of the meniscus was at 1042. It's probably all wildly out anyway as I'm not correcting for temperature.
