The spirit has underdone an experimental toasting method that utilizes a rotating metal cylinder inside the cask to slowly toast the exterior surface of the barrel and open its pores. The heat used for the process comes from Icelandic magma rock to give it a bit more intrigue than traditional fire roasting methods. [Master](https://www.trendhunter.com/trends/glenfiddich-1) Blender Stephanie Macleod commented on the Dewar’s Double Double Scotch saying, "Our motivation is always to aspire to make ever greater whisky. Curiosity and experimentation allow us to respond to the present and future desires of whisky lovers, and the Magma Stone Toasted expression embodies this philosophy, as we believe we are the first whisky to use this technique." ## Trend Insights (Trend Hunter) - Score: 4.5/10 - Popularity: 42% | Activity: 54% | Freshness: 38% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Drinking](https://www.trendhunter.com/drinking) ## Key Themes ### Why This Trend Is Growing - **Experimental Toasting Techniques:** The use of Icelandic magma rock for toasting offers a new level of intrigue and flavor complexity in spirit production. - **Adventurous Flavor Profiles:** Consumers increasingly seek bold and unique flavor experiences, driving innovation in crafting distinctive spirit profiles. - **Sustainable Heating Methods:** The adoption of earth-friendly heat sources like magma rock reflects a growing trend towards sustainable production processes in the beverage industry. - **Barrel Innovation in Spirits:** Innovative barrel treatments like the rotating cylinder method are redefining traditional aging techniques and expanding flavor possibilities. ### Industries Being Reshaped - **Spirits and Distillery:** The spirits industry is witnessing a revolution with the incorporation of unconventional aging processes to attract adventurous drinkers. - **Sustainable Materials:** An industry committed to sustainability will benefit from exploring natural and eco-friendly resources, like magma rock, in production methods. - **Luxury and Premium Goods:** Premium spirits utilize innovative methods and unique material sources to differentiate themselves as luxury offerings in the market. ## Related on Trend Hunter - [Quadruple-Aged Blended Whiskeys](https://www.trendhunter.com/trends/blended-whiskeys.md) - [Japanese Oak Cask-Finished Whiskeys](https://www.trendhunter.com/trends/japanese-smooth.md) - [Luxury Whisky NFTs](https://www.trendhunter.com/trends/dewars.md) - [Limited-Edition Golf-Inspired Whiskies](https://www.trendhunter.com/trends/champions-edition.md) - [Double-Matured Scotch Releases](https://www.trendhunter.com/trends/lagavulin-distillers-edition.md) - [Global Scotch Whisky Campaigns](https://www.trendhunter.com/trends/heres-to-the-story.md) - [Experimental Scotch Whiskey Spirits](https://www.trendhunter.com/trends/ardbeg-anamorphic-scotch-whiskey.md) - [Fruit-Forward Blended Spirits](https://www.trendhunter.com/trends/dewars-french-smooth.md) - [Flavor-Fused Whiskys](https://www.trendhunter.com/trends/glenlivet-rum-and-bourbon.md)
