Purpose of the Study:

• To review the crucial role of yeast in Scotch Whisky production and its influence on flavor.
• To assess the potential of non-conventional yeasts from brewing and winemaking as Scotch Whisky strains.
• To examine methods for evaluating new yeast strains for Scotch Whisky applications.

Main Methods:

• Literature review of yeast's role in Scotch Whisky fermentation.
• Examination of non-conventional yeasts used in brewing and winemaking.
• Review of methodologies for new yeast strain evaluation.

Main Results:

• Yeast fermentation is vital for alcohol production and the generation of volatile compounds (esters, higher alcohols) that define Scotch Whisky flavor.
• Specific yeast strains significantly influence the final flavor profile of Scotch Whisky.
• Non-conventional yeasts from other fermentation industries present potential for Scotch Whisky flavor diversification.

Conclusions:

• Yeast selection is a critical factor in achieving desired Scotch Whisky flavor profiles.
• Exploring non-conventional yeasts offers opportunities to innovate and expand the sensory characteristics of Scotch Whisky.
• Standardized methods are needed for evaluating the suitability of new yeast strains for Scotch Whisky production.
