Take a look at this rare glass defect that our QC folks caught on the bottling line! It's a washer from the forge imbedded in the bottle wall. Normally, the difference in thermal expansion coefficients between the metal and glass would cause the bottle to weaken and break as it cooled. That it survived and was filled is astounding. #foodscience #enology #wineindustry #packaging #glassblowing #latergram #thermodynamics #allthewine
