From when boiling started to when you first drew off spirit, how long did you allow for the still to stabilize? I havent done any refluxing distilling, but it seems important to allow the various fractions to "stack up" before drawing off. This could take hours. Can you describe your setup?
- The heads will smell similar to your wife's nail polish remover as it contains high amounts of acetone. The hearts (body) will smell like something good to drink. The tails will have an unpleasant smell not unlike a wet dog or wet cardboard. You can guesstimate the amount of hearts based on the amount of mash and its ABV (using initial and final specific gravity readings from your hydrometer). I would collect in small jars until you become familiar with your setup. Did you have a cold when you ran the still?

Subject: [new_distillers] Heads, body and tails
Hi I am new to the group and to distilling
I built a reflux still and on my first try I could not destinguish when the heads were finished and the body commenced. Both smell and tongue tip taste remained the same throughout
I could destinguish the tails because of the rise in temperature
Please could anybody help???
- Does that mean its boiling away for an hour ... or are you saying you slowly ramp up speed and it takes an hour to start drawing off?
I guess I read to read up on the "stacking up" stuff!

- I ramp up the initial wattage to about 2500w to heat the wash (15 litres). When I feel the bottom of the column getting hot ie the hot vapour has heated the sides and "roof" of the boiler and is now hitting the column, I turn down the boiler to 1200W as it slowly climbs the column. You know when the vapour is at the top when your thermometer starts to shoot up, if you left the boiler at 2500W at this stage the vapour could shoot right out the top bypassing the condenser. As its refluxing I put a glass jar above the column outlet to check no vapour condenses on this and is retained in the column Obviously if the temperature at the top of the column does not go up you need to add more heat. If the vapour condenses above the column reduce the heat. Once set and the temperature remains constant (+-0.1c)for 1/2 hour I then start take off.
