I have to say that I am a little bit stumped.
If I consider the first group of wines, the Bollinger stands out for being full-bodied and dominated by red grapes. The Pierre Peters is a Blanc de Blancs, and while pretty full bodied for a Chardonnay Champagne, it is still much lighter on its feet than Bollinger (Laura and I actually had the Bolly NV and Peters NV side by side last week). I have never really been a fan of Billecart, so won't comment there.
I am a big fan of Aubry, but I do not consider their NV to be particularly full bodied, despite the high level of Meunier. I tend to find Meunier (which both Laura and I love by the way) brings lots of up front fruit, but not a ton of depth.
Have you tried Billiot? Billiot and Bollinger pretty much duke it out for favorite producer in our house below the ultra-prestige level of Krug/Salon.
There behind the glass lies a real blade of grass. Be careful as you pass. Move along. Move along.
