Quality Checking Vinegar Tinctures: The Meaning of Cloudiness
There have been a lot of vinegar tinctures and infusions ongoing in the LisaLise lab for quite a while now. Some of it has been research, some of it is product development, and all of it continues to be fun and exciting work.
Although using vinegar as a solvent might seem brand new to some, it is nothing new.
Vinegar tinctures and extracts have been around for centuries. Most of them have been made for internal use, but sometimes also for external use (check this post for a bit of history about the use of 4 thieves vinegar).
Vinegar Tincture as a Cosmetic IngredientEven though tincture making has been around for ages, I'm happy to experience such a rapidly growing interest in making vinegar tinctures specifically for use as cosmetic ingredients.
And with growing interest comes an increase in questions.
Some questions have come from folks who bought this book, some have popped up via my Instagram account, some via Facebook, and some are from regular readers of this blog.
And because we're going to be doing a few skincare projects that include vinegar tinctures on this blog in just a tic, I decided to get busy with a little Q-&-A-type-series about vinegar tinctures and infusions to answer your questions in one place.
Defining CloudinessCloudiness is used to describe any vinegar (or alcohol-based) tincture where the liquid is opaque. If you can't see through the liquid in the bottle, then you've got cloudiness.
To illustrate, the top of this post shows a cloudy tincture.
The picture was taken shortly after straining and bottling. This tincture was made with distilled white vinegar and crushed juniper berries.
A Cloudy Tincture Isn't Necessarily BadAn opaque tincture doesn't necessarily mean it is wonky. As you can see from the picture above, even a freshly made tincture can be cloudy.
Here are a couple of the most common reasons for cloudiness.
1. Type of Vinegar UsedOne reason for cloudiness could be the vinegar. Not all vinegars are the same.
In this post I showed you you to make a vinegar tincture using coconut vinegar. If you remember, my description of the coconut vinegar was 'frosted white'. If the vinegar isn't crystal clear to begin with, the end product won't be either.
2. Material UsedAnother possible reason for cloudiness is the material infused. Some herbs and plant materials disintegrate into particles that are so fine they become difficult to remove even after straining.
Juniper is one example. To extract the most from juniper berries, it is recommended to crush or grind them before infusing.
And that's what I did. These were whacked with a rolling pin prior to infusing.
Note how opaque the liquid is in the picture at the top. Despite being strained through several layers of muslin and followed by 2 passes through paper filters, the liquid is still cloudy.
If the material is the cause of the cloudiness, to all you need to do is let the tincture stand undisturbed for a while.
Below is one of the bottles (after some use) and a couple of undisturbed weeks in my ingredients fridge.
Seeing residue settled at the bottom of a bottle might look worrying, but in this instance, it's a bit of good news.
The clear liquid that took 14 days to achieve by letting nature take its course might have been achievable with advanced filtering equipment, but that's not even necessarily the case.
Even some commercially produced tinctures will have residue. I've experienced this on more than one occasion.
Tip For Using Tinctures With ResidueIf your requirement is a crystal clear tincture and you have a very steady hand, it is possible to carefully pour off the clear liquid into a new bottle. Use the remainder of the tincture in a product that doesn't require a clear liquid.
Coming UpNext time we look at vinegar tinctures, we'll take a look at which vinegars to choose and what kinds of results to expect from different types of vinegars.
