Bubbles......

The Blessed Bubbles from Champagne... An initial burst of effervescence occurs when the champagne contacts the dry glass on pouring. These bubbles may form on imperfections in the glass that facilitate nucleation. However, after the initial rush, these naturally occurring imperfections are typically too small to consistently act as nucleation points as the surface tension of the liquid smooths out these minute irregularities. "Contrary to a generally accepted idea, nucleation sites are not located on irregularities of the glass itself. The length-scale of glass and crystal irregularities is far below the critical radius of curvature required for the non-classical heterogeneous nucleation." The nucleation sites that act as a source for the ongoing effervescence are not natural imperfections in the glass, but actually occur either: where the glass has been etched by the manufacturer or the customer. This etching is typically done with acid, a laser, or a glass etching tool from a craft shop to provide nucleation sites for continuous bubble formation (note that not all glasses are etched in this way); or, to a lesser extent, ......On cellulose fibres left over from the wiping/drying process as mentioned by Gérard Liger-Belair, Richard Marchal, and Philippe Jeandel. It is widely accepted that the smaller the bubbles the better the Champagne. Dom Perignon was originally charged by his superiors at the Abbey of Hautvillers to get rid of the bubbles since the pressure in the bottles caused many of them to burst in the cellar. As sparkling wine production increased in the early 1700s, cellar workers would have to wear heavy iron mask that resembled a baseball catcher's mask to prevent injury from spontaneously bursting bottles. The disturbance caused by one bottle's disintegration could cause a chain reaction, with it being routine for cellars to lose 20-90% of their bottles to instability. The mysterious circumstance surrounding the then unknown process of fermentation and carbonic gas caused some critics to call the sparkling creations
