Cuveé M. Isaac Blanc de Blanc Vintage 2015 'BBB'
Awarded 91 points by Decanter in June 2025.
Dedicated to our late founder, the Cuvée M. Isaac Blanc de Blancs Vintage 2015 Barrel-aged Before Bottling – or the ‘BBB’ – is our next winemaking innovation.
Sourced exclusively from the estate’s oldest Chardonnay vines during the 2015 vintage, the BBB was fermented, kept and stirred in barrels over three years to better understand the effect that longer oak ageing would have on English sparkling wine.


Product Description
This release is the second in the vineyard’s Cuvée M. Isaac prestige category, a range crafted in honour of our late visionary founder, Malcolm Isaac MBE. Malcolm's unwavering commitment to making world-class English sparkling wine continues to be the driving force at Exton Park.
Sherbet Lemon in colour with a fine mousse, the nose is immediately inviting offering a rich toastiness with creme patissiere and white peach.
Creamy vanilla richness gives way to nuances of burnt orange, marzipan and praline with a hint of smokiness on the palette, adding layers of depth and complexity.
The finish is elegant and confident, leaving a lasting impression and impeccable balance.

I have been waiting in anticipation to share this magnificent wine which showcases the timeless ageing potential of the Exton Park Chardonnay grown on chalk. As a base wine the result was stunning. With bubbles, it is simply incredible.
The BBB is, so far, my greatest achievement for English Chardonnay.
