Blueberry Herbal Vinegar {a brain food!}
Beautiful blueberry herbal vinegar features ingredients that are good for your brain and body!
Learn how to make blueberry vinegar, plus how to turn it into a brain boosting oxymel (herbal sweet and sour syrup).

This recipe was inspired by an interesting study I read about blueberry vinegar and its potential to improve cognitive function.
“…The BV [blueberry vinegar] group showed significantly restored cognitive function in the behavioral tests. … “
Since I’ve spent my life struggling with attention and memory issues, and I unfortunately have the “Alzheimer’s gene”, I’m always on the lookout for things that are brain-beneficial.
With fresh blueberries in season, this is one I had to try!
In addition, I included a handful of herbs in my vinegar for added benefits. Feel free to leave them out, or add your own favorite herbs to the mix.

Brain-Friendly Culinary Herbs
Here are the herbs I added to my vinegar and why I chose them.
Following each herb is a link to a related scientific study that may be of interest. (I also consulted favorite herbal books, since science has barely touched what herbs can do!)
I chose fairly common kitchen or garden herbs and used just a small amount of each, similar to the amount used when cooking. Still, if you have any health concerns, are on medication, pregnant or nursing, check with your health care provider before using home remedies like this one.
- basil (I used purple) – high in antioxidants (STUDY: improves memory & motor skills after stroke)
- borage flowers – protective of memory, adrenal support (STUDY: borage & Alzheimer’s disease)
- rosemary – a classic herb to improve memory (STUDY: rosemary & spatial memory; STUDY: benefits of low doses)
- thyme – anti-inflammatory (STUDY: thymol from thyme neuroprotective)

How to Make Blueberry Herbal Vinegar
- Fill a jar about half way with fresh blueberries.
- Add several pinches of fresh herbs, if you’d like.
- Pour vinegar into the jar until it’s almost filled.
- Stir with a knife or chopstick to release air bubbles, then add more vinegar if needed.
- Cover with a non-metallic lid and let steep for 1 to 3 weeks.
- Strain and store the finished vinegar in your fridge for about 4 to 6 months.
- Alternatively, infused vinegars can be processed in a water bath canner for 10 minutes to increase shelf life to 9 months to 1 year.
Tips when infusing vinegar:
- For the vinegar portion, use white wine, red wine, or apple cider vinegar.
- Place a layer of parchment paper or plastic wrap between metal lids and vinegar to prevent corrosion, or use a non-metal top.

How to Make a Blueberry Herbal Oxymel
An oxymel is an herbal sweet and sour syrup that’s used for medicinal purposes.
They’re often used for respiratory issues, but in the case of this blueberry oxymel, I’m using it for brain benefits.
(Read more about oxymels in my article: How to Make Medicinal Vinegars & Oxymels.)
- Combine equal parts of honey and strained blueberry herbal vinegar in a small jar.
- Taste to see what you think of the balance of sweet and sour.
- If you feel the mixture is too sweet, add more vinegar. If it’s too sour for your taste, add more honey.
- The amount is flexible since both honey and vinegar act as preservatives, so you can’t mess up with this recipe!
- Stir the honey and blueberry herbal vinegar together; it might not blend well at first, that’s okay.
- Store in a cool place or the refrigerator for around 6 months.
Take oxymels by the spoonful. I try to take 1/2 to 1 tsp one two times a day, with a meal. (I just guessed on that dose, you may want to take more.)
You can also stir a spoonful of oxymel into a beverage such as lemonade.

Ooh I love this idea! I get scattered at times too and feel like as I get older, my brain has trouble focusing. I wonder if this could be used as a base for a shrub even.
Hi Lisa! So happy you like the recipe! That’s a wonderful idea to use it as a base for a shrub! :)
Jan, you’re the BEST! I am so inspired that I’m going to self-teach about herbal healing – just for my own education/knowledge.
Warmly,
Michelle
Hi Michelle, That’s amazing to hear! Self-education is such an important part of life – continually learning and enjoying new ideas is the best! Happy herbal adventures! :)
Thank you! I appreciate your taking the time to share your amazing discoveries!
And bless you for adopting those kittens and their Mamma!
Hi WinterWren! So happy you like the recipe! We are so in love with the kittens & mama cat – they are enriching our lives too! :)
Hi Jan,
Since this is using fresh berries should it be steeped in the refrigerator?
Thanks!
Melody
Hi Melody! You could infuse in the refrigerator if you’d like, but it’s not necessary. According to my Ball Blue Book of canning & preserving, you can store vinegar while it’s infusing in a cool dark place for up to 4 weeks.
This makes a very tasty oxymel! I just finished my batch today. We typically make (and take) an anti-inflammatory oxymel (“fire” cider), so this one intrigued me especially since I grow all of the herbs in this recipe and I can always use a brain boost. Thanks so much!
Hi Amy, So happy to hear that you like the recipe! :)
Hello Jan:
Thank you for sharing your story with us. I do have one question would this vinegar oxymel work using frozen blueberries and if so would you let them thaw before mixing in with the dried herbs and vinegar (in winter)?
thank you and enjoy your kitties
Yvonne
Hi Yvonne! Yes, you can make this with frozen blueberries. I would let them thaw & drain the extra water off before mixing in with dried herbs & vinegar in the winter.
Homespun Seasonal Living has a great article on this: 😊

This is so very interesting and easy to do.
How can this blueberry vinegar be used?
Hi Sue! I mix it with honey to make an oxymel (sweet and sour syrup), but berry vinegars are also really good to use in vinaigrette or marinade recipes.
I have a few ideas in my blackberry vinegar article – just use blueberry in a similar way:
