Experimentation...

Had some 6-packs and family packs to experiment with over the weekend so a little trial & error were in order.  Had some successes...

• The Shiner Black Lager over Hornsby's Cider turned out nice.  The "Guinness" labeling on the glass really makes the top layer dark beer stand out!
  
• The Belhaven Scottish Ale over Hornsby's Hard Cider had some layering but kind of fuzzy and, with the Belhaven not being that much darker, the effect was a little underwhelming. Won't be having those two together again.
  
• The Shock Top Belgian White over Shiner 101 turned out OK for a clear / cloudy layering effect but it was definitely a bit fuzzy.
