Duca di Salaparuta chooses the most suitable cork for each type of wine, its longevity, its sensorial characteristics and the type of bottle used. One-piece corks in natural Portuguese cork for still wines, agglomerated cork stoppers for white wines to drink young, and ‘birondellato’ twintop corks for sparkling wines… Every wine has its own cork. Each small batch of corks is verified using chemical and microbiological checks, and by our Technical Team tasting panel. Acceptance of the batch of corks is based on the combination of all the checks carried out, all of which aim to guarantee the highest quality and to minimise the risk of defective cork odours. The choice of the best supplier is fundamental but not sufficient in itself: the corks must also be analysed using oenological, analytical, critical and innovative techniques, based on latest generation technologies.
