Just so we're clear, I'm not saying it's not safe but I don't know anything about the chemistry and reactive properties of various types and grades of plastics. However, if a reputable manufacturer produces a product, like the Essencia Filter System, that they say is specifically designed for Ethanol up to 55% then I will accept that product as being safe for the intended purpose.

Just wondered as I was thinking about fashioning a funnel out of a unused hdpe milk type bottle.
I was thinking,
Cut the bottom off,
Invert said bottle,
Use a bored demijohn cork with a short length if symphony tube
To my EZ inline filter which would then feed into a demijohn below.
This should probably now be in the filtering section but wanted to know about the hdpe first.

I only use glass or stainless steel so I'll never find out if it's safe or not.

So is hdpe safe for short term 40% storage?!

Chill AM,
I think we both paddle the same boat.
I too only collect and store high ABV spirit in glass,(I don't have the option of stainless storage).
And were I able to distill at 95.6%,no way would I let it drip into plastic.
The point that I was trying to make was that if the big distilleries,with their chemistry backing,feel that it is safe to bottle into PET plastic,which I grade as one below HDPE,then my short term use of HDPE,for low ABV ,I consider safe.
I also want to challenge the "laws" oft quoted from that other distilling site.
Equally,every shrink-wrapped package from a supermarket that I have consumed in the last many years,and all the bags of frozen peas etc may have contaminated my body.
I live on an organic farm, no chemicals used here for more than 25 years,and we produce much of our own veg,fruit and free range meat.

Perspective and reality.
Robert.

I understand where you're coming from but just because someone is paranoid doesn't make them wrong!

There are all sorts of plastic containers out there and I, for one, have no idea where they've come from or whether the markings on them are genuine or what they were used for in the past. ...my paranoia

For me, the document you posted uses too many instances of "not very soluble in ethanol..." and "...resistant to most things... to be considered a definitive reference about the safety of using plastics in contact with ethanol intended for human consumption and, in the absence of qualified, absolute assurance, it is perhaps safer to look to alternatives where the qualified, absolute safety assurances are available.

If the alternatives to plastics were so wildly expensive and/or unavailable I'd be more inclined to consider their use but I'm not an industrial chemist so I don't know for sure that it's totally safe to use plastics with ethanol up to 95.6% ABV and for that reason I err on the side of caution and recommend everyone who asks to do the same.

I know I can absolutely clean and sterilise glass or stainless steel and I know for certain that nothing will 'weep' from those materials into my ethanol.

For me it's "better safe than sorry" everytime

Just my two cents worth on this topic,as I suspect many folk are too paranoid.
I never worried about just how much 'plasticiser' could be be squeezed into the 12 gram plastic spout of the Smart still when it was my only means of distillation,which may then leach out,into the many litres of alcohol,and poison me.

I cheerfully store tails in MDPE.I have even collected strip in it,but not stored.
From there it is collect and store in glass.
This summer friends that I taxied from the airport presented me with a bottle of my favourite blend,Famous Grouse,duty free,in a PET bottle.It tasted as always,and I didn't notice the nasties,if they were there.

This is just a little sensibleness that I found online.
It is your body,be responsible for it.
But for goodness sake don't be a-feared by the scare-mongers.

Robert.

I have a friend at work that love's his westons cider .. which comes in rather nice 2.1 litre mini demijons with hand on the side ...

The odd one passes back with something nice in it .. and it's amazing how many I have accumulated lol !!!

I have a 50l SS keg with just a drain tap fitted that I use for storage of low wines and four 19l Cornelius Kegs for ageing spirit on oak. Before I acquired this collection I had to use 3l preserve jars and it was a right pain I the bum

Stainless steel milk cans (50L)work great. I have 20 of them and use them for everything except fermentation. And they dont break.

As always, glass is the best, as is stainless steel.
I have friends save all their empty wine bottles. (I have a lot of drunken friends).
I too sometimes have the need to store feints. I hate using my aging jars for this.
If you must store alcohol in HDPE, make sure it is low proof and only for a short period.

A couple of weeks ago Amaark raised the question of using HDPE for distilling.

His statements related to the general use of the materials for distilling and I replied with a negative response due to certain components of the distillate being at a high perentage and a high temperature.

Your question is somewhat different due to the low strength and lower temperatures that you will encounter.

The following table is an extract from a study of lots of countries and their current usage.

S = Suitable
NS = Not Suitable
L = Limited Usage

From the table it appears that HDPE would be suitable for low strength low temperature storage, but dont get over confident and stick one of them under your column output.

As an aside - I was at the local dump/recycling plant dropping off some building rubble. There was a skip for glass, next to the skip was a sign which said words to the effect "Please put wine demijohns on the floor outside of the skip" I asked what the sign was all about and was told that one guy came round every now and again to take them away, a couple of calls later 10 demijohns at £2.00 a pop.
