Fermentation times

[Hamish Jones]

I have just been using dried yeasts as a constant while I get myself fully conversant with all grain brewing, I haven't been using starters but my next step will be making starters before going to liquid yeast, lately my brews have taken about three to four weeks to fully ferment out with US-05, all brews have been sitting aroung 16 degrees pretty consistantly, has anyone else found this yeast to be slow fermenting lately or is it something peculiar to my brews, I have used it in the past and found three to seven days its all done

It has been a whole range of beers from high strength IPA's to lower strength Saison's so no real pattern to speak of, any thoughts why it's taking so long, or am I just being impatient as my kegs are empty?

I just did a "fake" lager using 2 packets of 05. It sat at 13deg for 3weeks in the fermentor before bottling and was just fine. OG 1.050, FG 1.009.
