- Reduced structuring and maturation turnaround time
- Enhanced anti-oxidation effects
- No need to filter out chips or wood powder from tanks
- No volume loss in the tank and no top-up as typical with barrels
- Improved ease of stock volume administration.
liQuerc Liquid Oak Concentrate
A natural wood concentrate for improved wine, beer, and spirit making outcomes.
The liQuerc product provides the same mouth feel, structure, flavour enhancement, with increased stability and longevity (through its strong anti-oxidative properties). It also has significant production benefits because of its liquid form and thus rapid integration.
Benefits of liQuerc
- No absorption or adsorption loss of colour or flavour as the wood is in solution and there is no sticking to the wood particulates
- Authentic wood associated mouthfeel, structure and mid-palate richness
- Repeatable quality product year after year – no wood or cooperage variations
- Extremely cost competitive when compared to staves or other new wood treatments
- Shortened production times and thus tie up of working capital
- Extended shelf life through wine stability and oxidation protection
The liQuerc Process
liQuerc makes two main products – MONO and POLY and a newly released Bourbon product. The MONO and POLY names refer to the molecular structure of the molecules formed by their respective uses in the beverage industry.
The MONO extract is made by curing the wood so that the sawdust flavor is removed and the molecules remain in a monomeric form. Polymerization is restricted and the monomers react immediately with the beverage constituents to form short molecular chains.
The POLY extract is a toasted selection of French and /or American wood, expertly blended to remove some of the tannic constituents.
The Bourbon product is an extract made from oak wood that has been toasted and the bourbon flavor developed to match that of American bourbon.
Dr Woolf Katz is the visionary scientist behind liQuerc’s range of products and applications. A doctorate in microbiology and a medical scientist, he perfected the art of extraction and concentrating during his tenure as the lead scientist at the Biovac institute. Dr Katz has spent the past 25 years working on the formulations presented as liQuerc Mono and Poly with a range of application.
Having originally approached the problem from a sustainability angle (not enough trees to supply the wood needed by the wine and spirits industry) he quickly realized the further production and quality benefits achievable by use of his ‘liquid wood methodology’.
Dr Katz having started his experimentation in the early 1990’s first supplied then up and coming wine maker, Neil Ellis in 1995.
We thankfully acknowledge and pay tribute to Neil Ellis and subsequently his son Warren who has been part of this story for over 20 years, and have remained loyal to the use of this product to the point of adapting their wine making style around the use of our products
Other respectable SA winemakers whom Dr Katz have worked with over the years include Ken Forrester, Martin Meinert, Guy Webber, and many more.
Working with such great wine makers have allowed Dr Katz to continue learning, developing, and refining these formulation to where we are today – the culmination of 25 years of work.
