Plenty of Champagnes like your "superior" brand Dom Pérignon have apple notes.
Of course they don't serve 400EUR Champagne in Delta One but no complaints here about awful apple flavors last month on my AMS-MSP-AMS trip when the FA's served me Delta's cooled Champagne Gardet Premier Cru with 'vibrant sweet apple and red fruit notes in the nose and palate'.
If you don't like flavors may i suggest their San Pellegrino.

If any of you ever fly to/have a stop at CDG; within one hour you are in the Champagne area. Plenty of smaller Champagne houses/farmers who sell good Champagne at a great price-quality ratio.
