Testing and evidence
The evidence from centre confirms Vinalchemy significantly improves colour density, optimises phenolics and tannins, harmonises acidity and reduces volatile acidity and produces wines statistically closer to naturally aged exemplars.
Plumpton evaluation - tested & certified
Test context
Within the tested conditions
The evaluation reported statistically significant treatment differences at p < 0.05 in selected chemical metrics and concluded that Vinalchemy accelerated ageing-related reactions under those conditions.
Operational meaning
The Plumpton evaluation reported different responses and estimated chemical-age changes across example wines.
That variation is operationally important: a programme should be developed for the actual wine, not assumed from a different wine or vintage. However once in use over several vintages, certain parameters can be recalled and applied, reducing testing times.
The VL250 sits between evidence and production, allowing the winery to test, taste, refine and approve before scale.
Double-blind sparkling sensory test
The Technical Data Sheet reports a double-blind triangle sensory test on Plumpton Sparkling Rosé wine, comparing treated and untreated base wine.
The 87% result refers specifically to 13 of 15 participants in this test and should not be generalised to every wine or audience.
A wine-specific starting point
Read the summary, then test the actual wine and let the winery’s own sensory and analytical review decide whether the result should progress.
