Testing and evidence

Sounds too good to be true? That’s why we tested it.

You shouldn’t have to accept our claims about wine on trust.

Testing by Plumpton College’s Wine Research Centre evaluated 36 wines in triplicate. Under the tested conditions, it reported statistically significant differences in selected chemical metrics and concluded that Vinalchemy accelerated ageing-related reactions.

Signed conclusion

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

Wine-specific responses matter.

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

Significantly different. Preferred by 13 of 15 participants.

The Technical Data Sheet reports a double-blind triangle sensory test on Plumpton Sparkling Rosé wine, comparing treated and untreated base wine.

13 of 15Preferred the Vinalchemy-treated wine

87%preferred the Vinalchemy-treated sparkling wine in this reported test.The brochure identifies the preference question as anecdotal within the test.

The 87% result refers specifically to 13 of 15 participants in this test and should not be generalised to every wine or audience.
