Planning your first Run

So your wash is fermented. Now comes the fun part, making your first run. This article is intended to help plan your first run. This is for a pot still, but the ideas relate to a reflux still.

Plan your work, work your plan, clean as you go.

Mental Preparedness

Distilling is dangerous. You need to be alert the entire time. It can take 2-5 hours for a run. Plan your time appropriately. You should never leave your still once you turn it on until you turn it off. Don't do this drunk. Seriously. It's a really bad idea. Late night runs can be bad too. You need your wits about you in case something starts to happen. You should plan your run when you are least likely to be distracted. If you ever need to walk away from your still TURN IT OFF.

Choosing a location

When you are planing your run there's a few things to understand. Safety needs to be key.

Fresh Air

Ethanol vapors are highly flammable. While you should not get any vapors out of the still but you should plan for that regardless. Having a supply of fresh air and moving air around while distilling is a good idea to keep any ethanol vapors below dangerous levels. A small fan near the still will be fine. It does not need to be pointed at the still.

Heat

Distilling creates a lot of heat for a long period of time. You'll want someplace that has a the ability to vent heat so that the room doesn't get too hot. Think of boiling a pot of water for 2-4 hours. That is equivalent to what you'll be doing.

Gas Heat

If you are using a propane burner you will need to be in an area that you can get tons of fresh air. Carbon Monoxide if one the things in distilling that can actually kill you. An open garage door is fine. Outside is best.

Electric heat

With electric heat you'll be taxing the circuit. If you plan on running anything else on that circuit you may overload it. Since you're working with water it should be GFCI. If it isn't you can get a power strip with an overload breaker. Any extension cords should be heavy duty.

For 220v make sure you have enough cord length to reach where you want to put the still. For 220 make sure you have the proper wiring put in place. Swapping out a 30amp breaker for a 50 amp doesn't mean you're ok. You need to have the correct wiring for it.

Cold Water Supply

You'll need a supply of cool water for the condenser or worm and dephlegmator if you have one. This will vary based on your still size. Most smaller still will need small amounts of water. This water does not need to be potable (drinkable) as it will not touch the distillate. A hose run from any facet is fine.

Hot Water Removal

A little more complicated is removing the hot water. The water coming out of a condenser will be hot. It can reach 160f-180f. It is not a good idea to put this water directly into a sink or drain. You can drain it into a metal pot or bucket and dump it someplace safe once you collect a couple gallons. If you have two pots/buckets this works well. If you're in the garage you can drain it into the driveway. Be careful with draining it into a yard. That hot of water will kill grass or other plants. Or if you have enough containers you can wait until they cool to ~120f and then dump it in a drain.

Prep your equipment in place

Put your still where you want to make the run. Assemble it without anything in it. Start hooking up everything. Make adjustments as necessary. Think about all the different piece there are to a run - collection, water on/off, adjusting the heater, charging the still, emptying the still, air flow, etc. Some basic questions:

Is anything close to where you are flammable or would melt?

How easy will it be to access everything once the still is too hot to touch like: Will you burn your self trying to get to the water flow?

Is anything touching the still that will be damaged by the heat?

Does the hot water have an easy path out? Will it flow easy or will it get backed up?

Where are you going to put the collection jars/flasks/etc that is SAFE and can handle the weight of the vessel plus the liquid? This is both for when collecting the product as well as before and after.

When are you going to charge it? Before or after everything is in place?

How are you going to charge it?

Prepping your still

Clean it up

Make sure everything is clean. It doesn't need to be sanitary. The heat and high alcohol content will do that. Get any dust or left over grime from previous runs off so that it can't affect the operation of the equipment or negatively affect the flavor.

Ensure the vapor path is open

The still needs to have an appropriately sized opening. This ensures that pressure does not build up in the still as it is operating, and does not collapse as it is cooling down due to vacuum pressure. Stills operate with very little pressure. It can build up and become dangerous. If left unchecked it can explode.

Hoses and connections

On the cold water side the hoses you use aren't super important. The hot water side is very important. If you use a standard water hose it can melt. Silicon works well but can be easy to kink. Fittings are not a huge concern. Small amounts of leaking is fine as long as it doesn't get into your distillate. Once hooked up pressure test everything at full pressure. While it is unlikely you'll use full pressure you may accidentally open it to full pressure. If hoses pop off then you will be scrambling to fix it in the middle of a run.

Still Setup

Put your still together in the location you want to use. Hook everything up as you were going to make your run. Make sure you have all the hoses hooked up. Pressure test everything. Make sure none of the hoses are touching the still.

Vinegar Cleaning Run

For a new still it is best to run a mixture of 50/50 vinegar and water through the still to clean off any residues from construction. It is a good time to check for leaks. This run will not mimic a run with alcohol. Vinegar has a boiling point above water. Use this first run to start playing with the condenser/worm. Don't let the condenser overheat. Feel the heat of the condenser tube from the bottom to the top. A well balanced will be cool at the bottom and too hot to touch at the top. If it's cold at the top you're putting too much water through it. One word of advice - it's going to stink. Make sure you have lots of fresh air for this.
