An Old Homebrewed Stout in a PET Bottle Surfaces

So here's a stout I brewed, god knows when.  It has to be a year and one half old, a kind of chocolate-cherry number that's been kept in a chilled space winter and summer, but not freezing.  

I love PET bottles for lots of reasons, but this is one-- the preservation of a beer seems way better in these bottle than glass.

It had a giant head, strong earthy aroma, pitch dark color, nicely bitter if balanced flavor, but a kind of thin mouth feel, which could have come from using cherry juice to carbonate the bottle.  It convinced me that I need to either follow recipes closer, or just use way more Maltodex and or Lactose when I use these liquid malt extract products, which I did with this batch, way back in 2012.  Nevertheless, I liked it better than Keegan's Mother's Milk I bought, which I liked very much.
