How to Identify and Use Distillation Cuts
Professional distillers rely on precise “cuts” during their runs to ensure only the finest components reach the final product; taking this approach at home could make the difference between success and failure of your batch run.
Practice makes perfect when it comes to learning distillation cuts. For beginners, smaller collection jars (half pint jelly jars are an ideal way to begin), should work best. Stripping runs should use these until temperature begins to decrease while spirit runs need them as soon as the ABV begins rising.
As soon as possible, cut away and discard any heads which contain compounds such as methanol, acetone or aldehydes that could compromise taste or aroma of finished product. It is therefore imperative that they are removed as quickly as possible from production line.
As soon as your hearts are removed from the run, set them aside for further distillation or use in recipes. They contain high concentrations of desirable alcohols and flavors – this part contributes to creating rich, smooth finishes with subtle complexity in high-grade rye whiskey.
