Sparkling Wine Making
Right now we have an event going on in the Rheingau which is called "Schlemmerwoche" ("week of feasting"). It means that for this week, the participating wineries open their cellars, have special events like this one - a tour about the making of sparkling wine or "Sekt" as we call it - or just put up some chairs and tables in their garages or living rooms and offer food and wine.
What you see in the photo is a cork for a champagne/sparkling wine bottle before it's been pressed into the bottle. You see, it doesn't have the typical shape yet, that we see when we open a sparkling wine bottle. The cork is lying on a "Rüttelpult" (which I'm going to explain later) and in the background you see people tasting the "Sekt".
