1. By Christina Alehem, Dieter Fuchs, Derya Kücükgöl, Peter Perskull The new wine stopper

2. Cork oak, Quercus Suber The cork oak grows in the western Mediterranean region Portugal accounts for 50% of world’s cork production Cork is derived from the bark of the tree The oak has a life span of 200 to 250 years The virgin bark is cut when the tree is 25 to 30 years old After that the bark is harvested every 9 to 12 years

3. Introduction Does a good wine need to have a natural cork stopper? Cork production cannot meet the demands of the industry, leading to a higher prize of cork Need to find an equivalent substitution to cork stoppers Existing alternatives: plastic stoppers, silicon and metal caps Have the disadvantage of preventing wine from breathing during maturation time in the bottle

4. Goal We want to introduce a good alternative to cork with all it’s positive attributes but to lower costs.

5. Characteristics of Natural Cork Stopper Elasticity Lightness Impermeability Positive attributes Negative attributes Cork taint in wine Increasing prize in the future It does not rotten

6. Characteristics of StrigoNovo Elasticity Lightness Impermeability Positive attributesNegative attributes No cork taint in wine Low prize It does not rotten No natural cork

7. Plastic cylinder with plate Grease-proof paper Collagen and Laminin Final product StrigoNovo

8. Collagen type IV from Danio revio Makes fine fibres Forms a natural barrier to cell migration Allows breathing

9. Laminin with its four binding-sites

10. Cellulose compared to heparin Cellulose

11. Heparin binding-site of laminin

12. Expression System EasySelect TM Pichia Expression Kit by Invitrogen Pichia pastoris is a methylotrophic yeast Methanol can be used as sole carbon source Promotor is induced by methanol High expression levels (up to 12 gram/litre) Product secreted Adaptable to fermentation (to 10.000 litres) No CO 2 incubators or tissue hoods needed Licence needed

13. Positive aspects of StrigoNovo Grease proof paper is already culturally accepted The paper absorbs a little bit of wine StrigoNovo can be produced everywhere StrigoNovo will not cause a cork taint The paper is brown Brown, granulated plastic cylinder

15. Test market StrigoNovo is primary intended for middleclass wines which constitute ~70% of the total wine market. The initial test markets will be in Switzerland, Sweden and probably the USA. We think that the population in these countries are more susceptible for changes regarding wine, compared to Italians, French or Spanish.
