I have a few questions and queries, (rambling musings perhaps is more apt a description!) please…I hope it is what you were looking for from your post?!
There are many different colours and shades of glass used to make wine bottles…clear glass for rose, to show off the colour I suppose, and which is generally consumed soon after bottling so not expected to be kept very long, so a tinted glass isn’t needed to protect the wine over many years from spoiling due to uv (assuming that coloured glass is used for that reason, and for no other, although if a wine is kept in a dark cellar I suppose it doesn’t matter what colour the glass is.) However, wines expected to be drunk young are sold in tinted glass bottles too, and I imagine it would take a few years for a wine in clear glass exposed to sunlight to spoil in anycase (or maybe not?) so why not sell them in clear glass? Is it a cost thing, is clear glass more expensive to produce than green or brown?
Is there a set rule to determine whether green glass or brown glass (and many shades of those colours) should be used? German Riesling for example tends to be in brown glass bottles, but sometimes green, so is it as I suspect random and up to the owner what he uses?
Also, is there a set rule to determine bottle shape used for different types of wine, or has it just evolved over the years and become the expected standard for a particular grape or region? If a traditional claret shaped bottle was used for a Burgundy wine it would taste the same, so is it purely historical why certain regions and countries use certain shaped bottles? It helps the consumer know what wine is on the shelf based on the bottle shape, so from a marketing and style perspective it is the way it has been done for years and there is no need to change?
Would it be possible to have red wine produced in a bottle where the colour could be assessed, to see how it was ageing? If it is in a dark green bottle that is impossible. Maybe with advances in technology and production methods a bottle may be produced in 98% green glass with a 2% window or ring in clear glass to see what colour the wine was? Or would that be a waste of time as the colour of wine is only a hint of how mature and ready to drink a vintage is, and so not worth the expense?
