theveganbrewer hit 1.010 FG on his 4.0 clone. I mashed at an initial temperature of 154* (which is 4* higher than the 150* recommended) however I used a 50 quart cooler as a mash tun so it was way too big for 11.5 lbs of grain and lost of a lot of temperature, which could account for some of the crazy attenuation I got, however most of the crazy attenuation comes from doing primary fermentation in my kettle (down to 1.009 in a week). For some reason (some think it is the shape of the kettle) I get significantly higher attenuation when I do primary fermentation in the kettle vs using my Better Bottle carboy. I've done head to head experiments with the same exact batch, so I know it makes a difference. As for the final 4 points of attenuation, it had another 3 weeks so I'm not so surprised as I usually get another 2 points of attenuation in the my beers that are only in secondary for a week. 70+* temps may have made a difference of a point or two, but it made it to 1.009 in a week and never saw a temperature higher than 66*, so I'm sure it would have hit 1.007 FG with another 3 weeks even if the temperature never went above 68*. My best guess is that the mash gave me 2 extra points, the kettle gave me 3, and the 70+* temps gave me 1. I like dry beers, but I can already tell this is much drier than Heady, so I'm probably going to do this clone in the future and either get a 5 gallon Igloo cooler for a mash tun, not do primarily in the kettle, or maybe both and see where my FG ends up.
