Enhance your Spirit Range.
Primary or Secondary aging using Quality Long Grain Gangutia Oak.
Create a market difference.
Alternative aging through the application of OAK MASTER ® infusion closures, enhances the analytical and sensory characteristics of spirits. Using PATENTED OAK MASTER ® closures we create a fascinating innovation for a classic sector. For vodka, rums, gin and any other liquor it balances the polyphenolic compounds extracted from the wood and provides other components. The OAK MASTER ® closures improve the qualities of the Spirits giving color, aromas and nuances of toasted oak in a month and a half after bottling.
Our system is an innovative, intelligent and educational resource that serves the interest and complexity of whiskeys and other spirits, and as such can contribute a great deal to quality.
Distilleries will then have the option of offering a different range of OAK MASTER ® infusion closures, which will give different qualities depending on the origin of the oak, degree of toasting and selected weight.
Spirits that adapt the use of alternative OAK MASTER ® infusion closures, find changes in their composition due to the addition of phenolic compounds and other molecules extracted from wood. Such compounds include lignins, hydrolyzable and condensed tannins, gallic acid, ellagic acid, aromatic carboxylic acids, and various aldehydes.
Different extraction rates are observed, depending mainly on the origin of the oak and the degree of toasting, reflecting sensory differences. Volatile phenols together with aldehydes, phenols and lactones showed an increase in 2 months. The ellagitanins were extracted more quickly during the first 4 weeks; after 8 weeks a significant decrease is observed. Lactones induced positive sensations of sweetness, while furan and guaiac compounds influenced bitterness and astringency. The spicy and vanilla undertones associated with eugenol, vanillin, and other scent chemicals are best balanced after 8 weeks. The extraction time of the released compounds varies depending mainly on the origin of the oak since the extraction time is longer in French oak than in American oak.
Three types of toasting are used in the OAK MASTER ® range of alternative closures: light, medium and heavy. This stage is considered to have the most important influence on the chemical composition of oak wood. Heat treatment causes the thermodegradation of some components of oak wood, which produces numerous volatile compounds. Furan compounds are formed through the thermal breakdown of carbohydrates; Volatile phenols come from the thermal degradation of lignin and oak lactones are the product of the dehydration of acids present in wood. Medium toast corresponds to the maximum synthesis of these volatile compounds.
The most potent contributors to the overall oak aroma are the compounds related to oak toast: vanillin, furfural, and 5-metzylfurfural. An important interaction between the perception of sweetness and the volatile compounds of the oak is also shown. The perception of sweetness is more noticeable with higher levels of lactone compounds, eugenol and vanillin. The levels of these compounds are positively correlated with the perceived intensity of the vanilla aroma. The overall woody character is positively correlated with the levels of guaiac, methyl guaiac, eugenol, syringaldehyde, lactones and vanillin, which is reasonable as the feel of oak wood is complex and is influenced by the presence of various wood extracts with active odor.
For example, the lactone in whiskey is an attribute that accounts for a woody and coconut character. The perceived pungency is closely related to the eugenol content, which is logical, since pure eugenol is described as similar to cloves.
French oak wood is abundant in aromatic compounds with a spicy and balsamic character. The high concentrations of eugenol (aromas of spices) and maltol (aromas of roasted, caramel…) are characteristic.
Its application in spirits involves:
• Increase in the aromatic complexity of spirit due to the transfer of vanilla and spicy aromas.
• Respect for the fruity character of the spirit due to a slow and progressive release of the characteristic aromas of the wood.
• Contribution of structure in the mouth due to its content in ellagitannin.
FRENCH OAK MEDIUM TOASTED
Rich in volatile compounds such as eugenol, guaiacum and isoeugenol, compounds that give the spirit aromas of black pepper, cloves and liquorice.
FRENCH OAK DARK TOASTED
It is characterized by aromas of dark chocolate, caramel, coffee, roasted, subtle spices, characteristic of noble wood.
American oak wood is richer in volatile compounds derived from the thermal degradation of lignin, but contains less ellagitannins. It contributes to improving the organoleptic qualities of spirit, due to the transfer of characteristic compounds, such as cis-whiskylactone (vanilla).
Its application in spirits involves:
• A minimal modification of the tannic profile of the spirit due to the low contribution of ellagic tannin. Less impact on the structure in the mouth than European oaks.
• High short-term organoleptic impact as it is rich in volatile compounds.
• This wood quickly gives off the characteristic aromas of wood.
AMERICAN OAK MEDIUM TOASTED
Abundant in polyphenols and phenolic aldehydes, originating from the thermal degradation of lignin and responsible for spicy aromas. The prized cis and trans whiskylactones provide an intense vanilla aroma.
AMERICAN OAK DARK TOASTED
It stands out for the presence of glycosidic polymers that give rise to toasted, caramel, roasted nuances, notably increasing the aromatic complexity of the spirit.
