Who We Are

1962 – The Idea
On a beautiful summer evening enjoying a glass of wine with his friends, Franz Tschappu saw the difficulties waiters had uncorking expensive wine bottles with the traditional corkscrew. That evening he came up with the idea to invent a corkscrew that is very easy for anyone to handle. In particular, the tearing and crumbling of the cork in expensive wines should be avoided. This was the spiritual birth of the “CORKY, made in Switzerland”.

1962 – Patent Application
After thorough product development and prototype testing, Franz Tschppu filed his patent for a “pneumatic Entkorkungsgerät”. Two years later the patent was issued to Franz Tschappu.

1965 – Start of Production
In 1965 the company Gisberger & Tschappu (later Girtag AG) located in Glattbrugg, Switzerland began producing and distributing the unique “CORKY, made in Switzerland” worldwide to more than 80 countries.

2007 – Acquisition
After more than 37 years of successful production and worldwide distribution, the owners were ready to retire and pass on the philosophy of “Swiss Made Quality”. Despite several takeover attempts by international and domestic companies in the wine industry, the right successor was found in the person of Franz Oeschger. Since April 2007 his company, “Franz Oeschger, Import – Export”, located in Oberflachs, Switzerland is sole owner of the pneumatic uncorker product “CORKY, made in Switzerland”. To date the existing customers and partners worldwide are supported and supplied with the product quality “CORKY, made in Switzerland” with the usual Swiss reliability. Franz “Oeschger, Import – Export” is a small family owned business located in the small Swiss wine community Oberflachs.

2015 – Website
Corky goes online with a brand new website and a new product design.
