Any Albariño (from Galicia) should suit you / her / (him?).
Monopole (Bodegas Cune / CVNE) is a traditional favourite (5.65 €)
My personal choice would be a Bodegas Olarra
Añares Blanco (6.30 €) or Señorio de Olarre Blanco (7.40€).
Thanks for that . My wife also sends her thanks and she says she will try them all, just so she can help others with a similar dilemma.
