Homemade Vanilla Update Week 4

I skipped week 3 pictures because I did not think there was much of a change in color.  I am not real sure there is much of a change with week 4 either.  From here on out the color might stay about the same as it is a pretty dark amber color.  I have been able to tell the difference in the smell of the vanilla each week.  On this 4th week the extract has a very strong vanilla smell.  I could probably go ahead and start using it now if I wanted to.  Mine may have gotten dark quicker because of me using some vanilla beans that had already been cut and soaked in my previous vanilla bottles.
