Natural Aqueous Tannins (NATAN®)

Oak Wise 100% Natural Aqueous Enological Oak Tannins represent a quantum leap in the science and efficacy of oak additions for beverage production. They are a family of liquid oak tannins which give winemakers, brewers and distillers complete control over all the organoleptic and structural elements that oak provides to beverages.

Our tannins are suitable for use in beverage production and comply with 27 CFR 24.246 of the Alcohol, Tobacco Tax & Trade Bureau (TTB) Electronic Code of Federal Regulations e-CFR when used at our recommended dosage rates.


Premiere is a range of structuring aqueous oak tannins. In wine, they can be added at primary or malolactic fermentation and aging. Premiere will assist in binding pyrazines, aid in color fixation, and tannin polymerization. In wine, the recommended dose rate for Premiere is 0.2 ml/L – 5.0 ml/L added as late as 48 hours prior to bottling. In spirits, Premiere can be added before bottling or during alcohol dilution prior to barrel aging.  For use in spirits, we recommend using Premiere up to 20% of the makeup of water volume.


Finissage is a range of clear finishing tannins for use in finished wines or to adjust the astringency in cider, beer or spirits. Finissage will soften mouthfeel and increase the fruit aromatics. In wine, the recommended dose rate is 0.2 ml/L – 5 ml/L. In beer and spirits, we recommend adding Finissage to the finished product between 0.5 ml/L to 5 ml/L. Finissage can be added up to 48 hours before filtration or bottling.


Premiere CT is a range of concentrated aqueous oak tannins. CT will assist in increasing the aromatics of oak characteristics such as toast, spice and the complexity of any beverage. CT will help produce a final product that denotes extended barrel aging. Dose rates from 0.1 – 2ml/L
