Nice little addition. BA has introduced a "guest champagne" at least in GF (presumably also CCR). Changes every month and is in addition to the usual tow (Taittinger 05 and Bolly Rose at the moment). Guest this month is De Castelnau's Blanc de Blancs Vintage 1999. They also have little printed tasting notes to go with it. I quite like it - fairly intense but good with breakfast

First I've noticed this so maybe it's been posted before.
