In cooperation with the best Italian winemakers, Gamba has developed a 500 litres puncheon for fermenting the best "premium" red wines. Gamba cooperage developed a 500 litres puncheon for fermenting the best "premium" red wines all over the world, thanks to the installation of a 316 stainless steel top door and to the construction of a support with wheels to allow the rotation of the puncheon during fermentation.
In particular, the research recognized that oak staves act like ideal and diffuse micro-oxygenators making it possible to:
• Eliminate unpleasant reductive aromas caused by stress due to lack of oxygen in the yeasts. An oak vat has proven to create ideal conditions for enhancing cellular reproduction and yeast activity.
• Allow the oxygen and oak tannins to immediately enter the complex chemical process, thus leading to the proper combination of tannin anthocyanins and as a consequence, greater color retention.
• The oxygen uptake on young wines and musts is beneficial for better color through anthocyanin stabilization and rounder wines through polymerization of tannins resulting in softer and longer chain of tannins and age worthy wines.
• Decrease the reduction of the tannin - anthocyanin content with respect to fermentation that occurs in other non-oak containers.
