<jats:title>Abstract</jats:title> <jats:p>A gas chromatographic method for the determination of alcohol in citrus juice by analysis of headspace is described. The volume of juice is not critical, but the bath temperature for samples must be constant. Juice samples should be analyzed as soon as possible, or kept refrigerated to avoid alcohol production by contaminating organisms.</jats:p>
