Ambra Automatic Resin Stabilisation Plant

Ambra is a tartaric stabilisation system operating at ambient temperature through the application of cationic resins. The ion exchange treatment consists of passing the wine through a column containing resin in cationic form.

The resins may be charged with sodium (Na+) or hydrogen (H+), or a mixture of Na+ and H+. When the wine is treated with resin in sodium form, Na+ is exchanged with K+ present in the wine; when the resins are charged with H+, the acidity of the wine would increase due to the exchange between the H+ ion (from resin) and the K+ ion (from wine).

This may be suitable for treating low-acid wine, which would benefit from increased acidity while being stabilised.


  • One or more cationic columns

  • 1 unit for wine supply to the column, drawing directly from your storage tanks

  • 1 unit for the automatic RO water supply to the column

  • Flow meters (magnetic type)

  • Conductivity meter

  • Pressure sensors

  • Complete automation

Sizes Available: from 100L to 1,500L of resin.
