Oesophageal motility and digestion of cream liqueurs in combination with common alcohol mixers.

When acidic mixers are added to cream liqueur curdling occurs. Oesophageal motility was studied in normal volunteers during ingestion of this mixture and the effect of combining with gastric juice was assessed in a simulated physiological environment. Twenty-four h ambulatory manometry and pH (n=22) and gastric studies (n=7) were carried out. There was no detrimental effect on oesophageal motility. The precipitation is rapidly broken down by the digestive process in the stomach.
