Dhavall Gandhi redefines Whisky Maturation for India:

 Introducing SOLARES Cask

Visionary Whiskymaker and maturation expert Dhavall Gandhi has revealed a breakthrough whisky cask designed for Indian* climates, in exclusive collaboration with José y Miguel Martín, Spanish cooperage and wine makers.

SOLARES has been designed to help Indian* distilleries scale without compromising on flavour consistency or quality, SOLARES also delivers significant efficiencies to the maturation process – solving one of the whisky industry’s most pressing challenges. 

Challenge & Opportunity

Dhavall Gandhi said: “Whisky maturation has traditionally been shaped by the cooler climates of Scotland and Ireland. But in tropical regions like India, accelerated extraction due to higher temperatures often results in imbalance – and the unreliable quality of available casks frequently leads to batch-to-batch inconsistency. Our SOLARES cask changes that narrative.”

“It’s not just about maturation – it’s about creating the foundation for scalable growth, without compromising on quality or consistency.”

Through proprietary transformation and seasoning techniques, each 225L ex-wine barrique – sourced from Rioja and Ribera del Duero – is precisely adapted to deliver balance, depth, and consistency, redefining the next frontier of tropical whisky maturation. 

Three Distinct Variants 

SOLARES casks are offered in three distinct styles, giving distillers the ability to shape their house character with precision and reliability:

1. DULCE – Rich & sweet.
2. MEDIO – Balanced.
3. SECO – Dry & complex. 

Sustainability, research and testing

SOLARES is not just about innovation – it’s about creating a more sustainable future for whisky production.

By transforming ex-wine casks instead of relying on new oak, SOLARES actively reduces deforestation, minimizes waste, and lowers the carbon footprint of cask production.

At its core, SOLARES is built on circular design:

• Repurposed casks – Eliminate the need for fresh oak harvesting.
• 100% renewable energy – All operations are powered by sustainable sources, resulting in a low environmental impact.

This innovation is backed by years of research and refinement in Puerto de Santa María, Spain. SOLARES casks are now actively used by Indian whisky producers, demonstrating exceptional performance, structural integrity, and cost efficiency in real-world production.

Additionally, SOLARES has been successfully integrated into the maturation of rum, and other tropical spirits, proving its versatility and consistency across categories.

Scalability

Through direct winery partnerships and large-scale sourcing, SOLARES delivers consistent, scalable quality—solving a critical challenge for Indian distilleries: inconsistent supply and variable quality that disrupt production planning and cause batch variability.

Casks are sourced in large batches directly from the wineries, creating a vertically integrated supply chain that ensures reliable, high-quality inventory. These casks undergo transformation within a strict timeframe, resulting in a cleaner, more refined spirit through a rapid, controlled process.
