Right- lets talk about wine:
The taste beat a load of cheepos from dodgy 2007 fruit drunk this year. Yes Nyetimber, when settled in the glass, and only pettillant, the taste was excellent, and head and shoulders above cheapo.

1) The mousse wants smaller, more persistent bubbles.
2) Body, perhaps adding some fruit grown under glass, will emulate the extra body from the best french champagnes.
