Scott’Tan™ Complex is a proprietary cellaring and finishing product. It is a blend of proanthocyanidic (exotic woods) and ellagic (oak) tannins. It enhances structure, aids color stabilization and provides anti-oxidant protection. It is less reactive and more polymerized than some other tannins, thus it integrates well and provides balance. It is particularly useful in wines with up-front fruit or where smooth tannin structure is lacking.

Recommended Dosage

Prior to Barrel Aging Red Wine
50-300 ppm
50-30g / hL
0.42-2.5 lb/1000 gal
Prior to Bottling (3-6 weeks)
30-100 ppm
3-10 g/hL
0.25-0.83 lb/1000 gal


During transfer or racking add Complex into the wine. Mix well to assure homogeneity. Following organoleptic evaluations, 2–3 further additions can be made subsequent to rackings. First additions should be made at least 3-6 weeks before bottling to allow for polymerization and settling.


Dated expiration. Unopened, the shelf-life is 5 years at 18°C(65°F). Once opened, keep tightly sealed and dry.

Product Notes

Note: Complex is best used prior to barrel aging. This encourages tannin integration in the wine over time. It may also dramatically improve a red wine when added prior to bottling. At this stage, Complex should be added at least six weeks before bottling to allow reaction and polymerization. Successful additions can be made closer to bottling, but this may result in less throughput during filtration.
