WLT 150 is highly versatile and can be used in anything from virgin spirit right through to a fully matured spirit simply requiring additional balance and slight oak character. Thus, factors like the initial profile, desired profile, and the process stage at which WLT 150 is applied could all affect which dosage is deemed most suitable. Furthermore, the optimal WLT 150 dosage rate will ultimately vary based on the distiller’s preference.
Recommended dosages, as utilised by many distillers, are typically between three and 15 mL of our product per liter of spirit at distillate strength. Once you have an indication of what dosage of WLT 150 should meet your needs, our dosage calculator is a convenient tool to estimate which volume of WLT 150 you might require.
For optimal results, if this will be your first time using WLT 150, we recommend that distillers carry out a simple trial by combining small batches of their own spirit (post barrel) with different concentrations of WLT 150 to identify their preferred dosage rates. We can provide a step-by-step proposed trial protocol for this simple test, should you require it.
As a homogenous liquid , WLT 150 readily combines with spirit at any stage of processing, and therefore dosing thereof is simple and practically effortless. Where barrelling is employed as a part of the distiller’s traditional manufacturing process, dosing should be after this stage and before bottling.
To ensure proper integration of WLT 150 into spirits, we do recommend that the treated spirit is gently agitated to ensure thorough integration . Although this step is not strictly essential, it can improve process efficiency and accuracy by introducing small volumes of oxygen which can accelerate the rate of integration of WLT 150 phenolics with the spirit. By ensuring that WLT 150 is well blended an entire production run can be more easily and accurately compared.
WLT 150 integrates with the core spirit on a molecular level, and this process is relatively quick – especially when the treated spirit has been blended through pumping over or gentle agitation. As with any barrels the interaction between the oak-derived molecules in WLT 150 and spirits results in smoothing and adds character to spirit. With WLT 150, these effects are observed more quickly than with the addition of barrel chips or staves. This contributes the development of the spirit and assists in accurate final blending. However, on full batches, we always recommend that distillers allow for at least two weeks before assessing the result of dosing.
WLT 150 is provided in 5 L, 25 L and 1000 L containers. For sampling purposes, 1 L and 30 mL bottles are also available.
