Summary:The invention discloses a distilling method for reducing fusel oil in baijiu. The method comprises the steps: firstly, distilling ripe mash at a slow speed under 0.2 to 0.3MPa steam, gathering fusel oil in foreshot and collecting the foreshot; rectifying the foreshot to remove the fusel oil to obtain base liquor. According to the method disclosed by the invention, the fusel oil can be gathered inthe foreshot through slow-speed distillation, so that only 10 to 30% volume foreshot is rectified in a following residue removing procedure, and 70 to 90% volume heart cut is prevented from being treated; thus, a rectifying amount is greatly reduced. as the alcoholic content of the foreshot is higher, enrichment and separation of the fusel oil are facilitated, and a rectifying reflux ratio can bereduced. Comprehensive results are that steam and electricity consumption is saved, a residue removing efficiency is improved, and easiness in production application is achieved. 本发明公开了种降低白酒中杂醇油的蒸馏方法，该方法首先将成熟醪液进行慢速蒸馏(蒸汽0.2-0.3
