I can't answer your question, but why do you do a stripping run to get the 45%? Isn't low ABV wash usually boiled and fed straight into the column?

Some European barrels have that extra piece to prevent the head bulging out. Their barrels are designed to last a lot longer than your bourbon barrels.

This how quite a few in Australia rack our barrels. I will add another layer of smaller barrels. Note gravel floor in my new bond store

13mm are very common in Australia. Email me pbignell@belgrovedistillery.com.au I might be able to express post to you. Take a photo to make certain we are talking about the same thing.

Thanks Jedd, I am trying to work out how to reformat

My barrel store is finally built, but before I put the barrels in I did an experiment BOND STORE FIRE. I had to go to great lengths with maths and physics to convince my fire engineer and the Tas Fire Service that a porous gravel floor is much safer than a bunded concrete floor in my new Belgrove bond store. Now that it is finally built it is easy to prove. There is a concrete pathway through the middle of the shed where I poured 700 mL of 90% abv heads, I poured the same amount on the gravel to the left. You may need to put your glasses on to see the flames on the gravel section. Please let me know if the link won't open. EDIT, IT DIDNT OPEN, SEE A LINK OF THE 2 FIRES SEVERAL POSTS DOWN

tenorbrew, "I don't use the built in pump, I have a separate pump outside the building. "

The biggest potential problem I see is the electric vacuum pump close to flammable liquids. I don't use the built in pump, I have a separate pump outside the building.

I have had discussions here before about micro bubbles of entraped air. The bubbles can get caught on the bottom of glass hydrometers, spinning the hydrometer can help get rid of them. The hand held Anton Parr snap series electronic devices certainly give false reading if small bubbles caught up. What range are your hydrometers? Are they certified? Before Anton Parr I did have a glass hydrometers with a very small crack in the glass bulb, took a while to figure out why readings kept drifting. Also floating a glass hydrometers in a narrow cylinder gives inaccurate readings. I think you are stirring for way too long. I use a paddle for a couple of minutes maximum. What is your pneumatic stirrer? Is it a high speed propeller driven by compressed air, or do you mean using air bubbles to agitate? High speed propeller could cause cavitation and bubbles of alcohol vapour. Following this topic.

In my opinion a turbity meter is unnecessary for checking the finished product. I shine my phone's flashlight through the bottom of the bottle, if I can't see any turbidity then neither can the customer.
-
For my information, what do you use a turbidity meter for?

The reason these burn slowly is because the liquid ethanol is below a layer of pebbles. This layer does 2 things, it keeps the flame heat away from the liquid so keeping it cooler, and oxygen can't get down through the small gaps in the pebbles to accelerate the fire.

From what I have found, ethanol is not classified as an environmental hazard in Australia, but in reality that would depend on the size and location of the spill. A flat concrete slab with coving(raised edges) that contains a spill would be a very dangerous situation. Have you ever seen a gas / petrol station area around the pumps like that? Imagine a fuel spill and your car is sitting in a pool of very flammable liquid. They all slope to the perimeter into a drain that goes to an explosion proof containment. Concreted barrel stores should be the same. 60% ABV ethanol that is soaking into gravel floor will, in most situations, be too cold to produce vapors any where near LEL (Lower Explosive Limit) whereas pooling on a concrete floor is more likely to produce LEL. If ethanol spills onto a gravel floor and catches fire it will burn very slowly. Ethanol fireplaces and fire pits in homes are examples of safely burning ethanol.

No replies yet. A simpler question to answer, what type of flooring you have seen in barrel stores?
