I have been having some problems with acetaldehyde in my all grain ales. It seems to only affect my higher gravity brews. Could it be that I am racking off the primary too soon and not leaving enough time with maximum yeast contact? I usuallly rack after three days of primary and then let secondary for two to four weeks. Fermentation temps are in the low to mid 60's. It is somewhat drinkable as I have a friend who actually enjoys it, but I don't. Any advice would be appreciated.
