Airline cutlery goes to good home Ive been doing some lab trials for our 2010 white wines (Riesling and Pinot Gris) to determine the level of Bentonite that will be required in order to make the wines protein stable. Its a fairly essential step as a wine that is not protein stable and stored too warm, can throw a fairly unslightly haze in the bottle that would make it practically unsaleable. So I set up a small bench trial with varying levels of Bentonite addition of a stock solution to a set volume of wine. This is usually in the range of 0.5 to 2.5 g/L. Each wine is then sterile filtered via that syringe at the bottom of the photo and then sat in a heated (80C) water bath for 6 hours. I find most of my wines tend to 'pass' at around the 1.0-1.5 g/L level. As I was setting up the filter I noticed that the knife I use to handle the filter sheets is in fact a piece of airline cutlery. Its from Ansett Airlines, whcih used to fly between NZ and Australia. Historians could probably date the piece. These days the thought that airlines routinely used to supply its passengers with small metal serrated knives is hard to believe.
