Key Points

ToF-SIMS reveals unique fragmentation patterns of oak wood compounds critical for spirit maturation, enhancing quality.
Reference spectra for important oak wood compounds, such as ellagitannins, were generated using Bi3+ ions in positive polarity.
This observational analysis provides essential data necessary for analyzing wood samples in spirits production.
Results may indicate the role of oak wood extractives in spirit quality, warranting further exploration of wood interactions.

Abstract

Initially used for fermentation or storage, oak wood barrels were found to enhance the organoleptic properties of spirits. Over time, wood extractives like ellagitannins and aromatic precursors have been linked to the quality of the spirits. ToF-SIMS being an ionization technique produces intense fragmentation patterns that are not fully understood, and reference spectra are required to analyze wood samples confidently. Here, positive polarity ToF-SIMS reference spectra of important oak wood compounds are involved in spirit maturation, using a Bi3+ primary ion species, are presented.
