Mix Acid is the acidification proposed by AEB for musts and wines. Mix Acid are formulations based on malic, lactic and tartaric acid that confer taste roundness to the wine, avoiding the appearance of acid lacks of balance caused by the prevalence of only one compound with regard to the others. These preparations by AEB have the characteristic of prolonging wines’ longevity and drinkability, strengthening the endogenous anti-oxidizing power of wines thanks to the lowering of the pH-value. The utilization of Mix Acid TLM showed that the total acidity and the stability of the natural tartaric acid is higher than the only addition of tartaric acid, sometimes even 30% more, thanks to the synergy of the three acids composing it.
