Mureddu Sugheri
Since 1938 Mureddu Sugheri is specialized in the production of high quality level cork stoppers.
Who we are
Since 1938 Mureddu Sugheri is specialized in the production of premium cork stoppers. The orientation towards the highest possible quality of product and the resulting radical choices made in this direction make that the Italian market recognizes us as the leading company in the 'quality in use' of the product . We count among our customers the largest wine groups and several of the most famous wineries.
What we do
Ensured the origin of the cork, begins its maturing and eco-boiling stage which is followed by a rigid selection of the semifinished material. Before proceeding to the production the quality control laboratory sets up a rigorous system which provides multiple tests among which excels the organoleptic check of each incoming batch with a representative sample of at least 400-800 stoppers and/or disks. The gas chromatography makes a verification of the analysis carried out by the panel of expert internal tasters and the material, only after the validation, continues the subsequent processing steps. Washes, IGEA and Te.De.Sys treatments, dedusting, turning, facing, electronic, manual and ponderal selection, ink and fire marking, surface treatment and packaging are the latest stages of our complete and unique quality chain.
High attention on quality
The Quality Control laboratory is one of the pillars of the business success. It deals with the analysis of raw, semi-finished and finished materials to ensure the highest quality and safety of the product. Coordinated by the Head of Quality Control there’re six highly specialized people who make multiple product’s inspections that the company always conducts with daily regularity since ever. The Quality Control laboratory is also the base of all Research & Development projects.
Organoleptic controls
Our total respect for the statements in the data sheets is the result of a rigorous system that comes out from a statistical study of Dr. Dallavalle presented in 1996 at the International Symposium of Cork in Pavia (PV - Italy) .
The scientific and representative photography of ALL incoming batch is given by the sampling of well 400/800 stoppers or disks .
Every morning our tasters panel make an olfactory test on each flask in order to detect any aromatic deviations in the product.
GC-MS analysis
The gas chromatographic analyzes are used in advanced analytical chemistry techniques based on the use of a gas chromatograph coupled to a mass spectrometer suitably adapted to their compatibility in order to identify and quantify, through a system of data analysis, the organic substances present in the sample analyzed . Mureddu Sugheri uses specifically the latest generation Agilent 7000 for the determination of T.C.A. and T.B.A. may be present in the cork.
