Crémant de Bourgogne recommendations?

We are taking my parents to burgundy this month & will go wine shopping for the golden anniversary bsh later this year.
My father turned his nose up at the recent TWS Roederer NV offer. As per 40th, he may opt for magnums of Triple Zéro, which appear available.
Alternatively, Crémant may be a viable option. My default is Picamelot BdB or BdN. I'm keen to avoid sampling any many, so any suggestions would be welcome.
Picamelot is located in Rully. Also based there is another specialist producer called Vitteaut Alberti. Opens Mon to Sat (unlike Picamelot which, I think, requires booking).
Further south, the co-op at Lugny has a wide range of crémants, and the nearby Azé co-op has a small but well-regarded offering.
Further south still the co-op at Chaintré has won awards for its single offering of crémant.
Mark, this may be of interest as you are 'on the ground' as it were at your Burgundy place hence can visit & taste/purchase direct - but I've just had an email from Domaine Agnes Paquet (wasn't aware/had forgotten I was signed up) promoting a new domaine website.

Included in "Nos Vins" are two sparkling wines - a Cremant and another (details of the latter on the site - 10% alcohol). The Cremant seems intriguing as, whilst the cepage is mostly from Chardonnay & Pinot Noir, small percentages of Aligote & Gamay are included. Whilst I've been a keen drinker of Agnes' Auxey Blanc back to the 2012 vintage I've no experience of the Cremant. HTH.
