Chignin has been written about a few times on the forum.
It's made from the Jacquère grape, which is not related to anything else and only grows in Savoie.
JP and JF Quenard are one of no less than 8-10 producers with the last name Quenard in the village of Chignin, one of Savoie's crus very close to the city of Chambéry. About 4 have been imported at some time into the USA.
You didn't mention the vintage but am presuming probably 2007 - JP & JF Quenard's wines
are brought into the USA by Charles Neal.
The lemony description is good and it's great as an aperitif as you said and good value.
Be careful not to mix up Chignin with Chignin Bergeron, which is made from 100% Roussanne (whose synonym in Chignin/Savoie is Bergeron).
