Liquid gum arabic for colloidal protection
IOC Flashgum R Liquid™ helps reduce the risk of colloidal deposits in bottled wine and cider.
-
Protects color in reds, rosés, and fruit wines
-
Gives perception of sweet and soft characters on the palate
-
Reduces astringency and increases the perception of volume and fullness in the mouth
-
Especially usefully in unfiltered wines, where it can minimize colloidal sediment
-
Can be added 24-72 hours before bottling and does not impact filtration throughput (if filtering)
-
Gum arabic derived from Acacia seyal
Stage of Winemaking: Pre-bottling
Requires Racking: No
Impact: Colloidal protection, sweetness
Format: Liquid
Formulation: Gum arabic
Frequently used in: Reds, whites, rosés, fruit wines, cider
Recommended Dosage: Bench trials recommended
Wine 400–1200 ppm (40–120 mL/hL) (1.5–4.5 L/1000 gal)
Usage: Flashgum R Liquid should be the last commercial product added to the wine.
Flashgum R Liquid should be added to wine that has already been protein-stabilized and pre-filtered (DE, lenticular, sheet filtration, or crossflowed) just prior to bottling. If available, it is best to use an inline dosing pump to incorporate Flashgum R Liquid into the wine. If an inline dosing pump is unavailable, add product and mix well to obtain even distribution.
If the wine will be filtered at the time of bottling, it is recommended that the addition be done 24–72 hours prior to bottling to allow for proper integration. Flashgum R Liquid is able to pass through final membrane filters (0.45 μm) found on most bottling lines, though filtration is not required after adding Flashgum R Liquid.
It is strongly recommended to conduct bench trials to assess Flashgum R Liquid’s potential impact on filterability and to ensure accurate dosing for colloidal stability.
Storage: Dated expiration. Store in a cool, dry, odor-free environment. Reseal opened packaging immediately.
