Are we there yet?

Not quite yet.  It's been about 10 days since my little pineapple vinegar experiment began.  Four days ago, I pulled out the last pieces of pineapple rind.  The color has definitely changed.  It's noticeably lighter.  However, it still smells quite beery.  Not so much like a vinegar yet.  I'm going to give it another week or so then give it a taste and see where we are.
