TANNIN
TANIN VR SUPRA®
Instantaneously dissolving (Instant Dissolving Process, IDP) ellagic
and proanthocyanidic tannin preparation for red wine vinification
SPECIFICATIONS
TANIN VR SUPRA® combines the effects of different tannins, which are selected and prepared for optimal technological
efficiency, without adding bitterness:
• Wine structural improvement by supplementation of the midpalate.
• Inhibition of natural oxidation enzymes (laccase, polyphenol oxidase) during harvesting of Botrytis-affected vintages
(more efficiently than SO 2
).
• Anti-oxidant action providing protection of the must and pigmented matter.
ŒNOLOGICAL APPLICATIONS
• Vinification of grapes that show a phenolic maturity deficiency or an unfavourable tannin/anthocyanin ratio for colour
stabilisation.
• Protection and vinification of grapes affectedby Botrytis cinerea.
• Improves fining.
EXPERIMENTAL RESULTS
• Inhibition of laccase activity on Botrytised harvest: up to 55% reduction of laccase activity after 4 hours compared with
only a 20 % reduction in the case of proanthocyanidic tannins alone.

• Protection and stabilisation of colour: combined (stabilised) anthocyanins, total phenolics and colour intensity are
enhanced for wine treated with TANIN VR SUPRA®.

PROTOCOL FOR USE
ŒNOLOGICAL CONDITIONS
• High anthocyanin content and/or tannin deficiency,
where the tannin/anthocyanin ratio 2 U/mL.
IMPLEMENTATION
The IDP process enables perfect solubility in wine and thus imposes no preliminary dissolution of the
tannins in water. Homogenous introduction into the bulk of the must or wine is, however, advised. It is
recommended to carry out a systematic pump-over or other homogenising action during the application.
TANIN VR SUPRA® can also be dispersed directly into the must in an intermediate tank during a pump-over.
• On sound fruit: add the total dosage during the first pump-over at the start of alcoholic fermentation.
• For cold pre-fermentation macerations (cold soaking): add the total dosage during the first pump-over at the start of
alcoholic fermentation.
• On a Botrytis-affected harvest: add the total dosage after crushing, little by little during pumping of the must. If
necessary, homogenise in the tank.
STORAGE
In sealed packaging. Use within the “use by” date.

Oenological Use
Properties : specific tannin of red wines encouraging the stabilisation of the colouring
matter by creating tannin-anthocyanin bounds and inhibiting the laccase activity.
Dosage : 10 to 50 g/hL (100 to 500 ppm).
Preparation : before use, prepare a 10 % water solution or add directly into the wine.
Incorporate during pumping-over to achieve optimum homogeneity (check the label and
commercial data sheet for guidance).
Remarks :
• Use an inert and clean container.
Storage & Optimal Date of Use
- Store in original packaging at room temperature (0 to 22° C) in a dry and odourless
room.
- Optimal date of use : 4 years after packing date. 4 months after opening (if the bag
is properly sealed).
