Tincture Making Failure


Tinctures with vinegars and alcohols, oil macerations and glycerites have been filling my stockroom and taking lots of lab time for well over a year now. It's because I have been doing a pile of research for of some upcoming publications (more on that soon).

Today, we're going to look at a tincture making blooper.

Above: a lovely herbal tincture in vinegar from earlier this year. At the time I started this brew, there were so many jars and bottles in use, I mindlessly grabbed what was on the shelf - a glass pickling jar with a metal lid.

You've probably already figured out what's coming, but it took me a while before I realized my mistake.



Ever wonder why vinegar is often packaged in plastic? Because vinegar will interact with metal.

And when it does, undesirable gunkiness*  happens.

(*highly scientific term)

The undesirable gunkiness has the amazing ability to find its way into every little nook and crannie of the lid and gunks up** your lovely tincture.

(**another highly scientific term)



Before discarding this tincture, I thought I'd share it with you.


Tip: use metal-free containers and lids when making vinegar-based infusions. Do you only have a glass jar with a metal lid? No worries! Place a piece of waxed paper over the jar opening before pacing the lid on. Voilรก - no metal contact!

You're welcome.

(isn't it great when you can learn from other peoples mistakes?)
