Application

Whiskey Lactone, also known as beta methyl gamma octalactone or methyl octalactone, is a chiral lactone compound naturally found in whiskey, oak wood volatiles, and wine aged in oak barrels. It is commercially supplied as a mixture of cis and trans diastereomers and is recognized as the primary olfactory contributor to the coconut, woody, and sweet aroma characteristic of oak aged spirits.

In the flavor industry, whiskey lactone is a highly valued flavoring agent that imparts a whiskey flavor, suitable for vegan and vegetarian foods. It provides woody, coconut, coumarin, wine, and creamy taste notes. It is widely used in coconut flavors, as well as peach, mango, and other tropical profiles. The compound is FEMA GRAS (No. 3803) and meets JECFA specifications.

In the fragrance industry, whiskey lactone has a distinctive woody coconut character with warm, creamy, vanillic notes and subtle toasted oak aspects that evoke aged whiskey barrels and fine spirits. It imparts authentic barrel aged character to fragrance compositions, adds woody complexity to gourmand and oriental fragrances, and creates sophisticated coconut accords. It features prominently in perfumery, including at high concentrations in fine fragrances.

In research applications, whiskey lactone is utilized in sensory science for studying the modulation of astringency in tannin solutions. It is also employed in flavor chemistry, wine and spirit analysis, and as a stable isotope labeled internal standard in stable isotope dilution analysis (SIDA).

Q2 What purity grades do you supply?
A Standard grade is 98.0 percent minimum (sum of cis and trans isomers) by GC. We also supply 95.0 percent grade and 99.0 percent grade for high end applications and analytical reference standards upon request.

Q3 Is whiskey lactone soluble in water?
A It is nearly insoluble in water. It is soluble in alcohol, propylene glycol, and most organic solvents.

Q4 Do you provide sample quantities for flavor or fragrance development?
A Yes, free samples are available for qualified US companies. Shipping fee applies for small quantities.

Q5 Is whiskey lactone approved for use as a food flavoring?
A Yes, it is FEMA GRAS (No. 3803) and meets JECFA specifications (No. 437). It complies with EU Regulation 1334/2008 and 178/2002, and FDA 21 CFR regulations. Please request our regulatory package for your specific application.

Q6 What is the odor profile of whiskey lactone?
A It has an intense, warm, sweet, coumarin like odor with woody coconut character, creamy vanillic notes, subtle toasted oak aspects, maple, and a slightly nutty nuance. At 10 percent dilution in dipropylene glycol, it exhibits tonka, coumarin, coconut, toasted, nutty, and celery notes.
