Booze in sigg bottles...

[domd1979]

Instructions say don't put alcohol in Sigg (or other aluminium) bottles. I'm tempted to ignore them and bung my sloe gin in one anyway (required for weekend walking/hostelling trip!!) as can't see any reason why not to..... Unless anyone knows any different?

Something to do with the coating on the inside? Alcohol may react with it and remove it?

According to Sigg, it's because in hot weather, the alcohol meay ferment & build up pressure.

Interesting... Sigg bottles seem reasonably substantial - they must be able to withstand a certain amount of pressure. Guess its OK so longs as you open carefully...

The alcohol reacts with the aluminium. I'd been using a Sigg bottle for several years as a fuel bottle and kept meths in it. I ignored the sludge and discoloration of the meths and used it without concern. Then I spotted someone's comments about alcohol and aluminium not being a good combination because of corrosion problems. Googling unearthed the fact that methanol is the worst culprit of the alcohol family.

Can't imagine a secondary fermentation with most alcoholic drinks that are decanted into the Sigg esp spirit based ones.

The bottles are lined, so guess your meths ate the lining first....!!

No there two types of Sigg bottle, lined (for use with fuel) and unlined for drinking from...

Ask Andy in Sigg... he'll know.

There are two types - but the drinking ones are definitely lined.

Not only back, but back in form.

Still using my original 1987 Sigg bottle, it has many dents to prove it age.

Don't put anything other than water into your Sigg, you will be tasting it for ages to come

Mine was a fuel bottle and I wrongly thought it was suitable for all liquid fuels.

If the lacquer lining was intact, not damaged by dents, most liquids should be fine. However some drinks will attack unprotected alumiunium, not because of the ethanol but because of acidity. Have you ever seen red wine or coke in contact with marble or onyx?
