How to Make a Strawberry Glycerite with Preservative

Lise

Today, we’re making strawberry glycerite.

You: Lise, it’s not summer, and there are no strawberries available.

Me: It’s summer in Australia right now, so somewhere on the planet, this is a timely post.

Important: Use the ripest, plumpest, freshest (organic) strawberries available to you for optimal results. If that means you have to wait for summer, then wait. Trust me when I say it will be worth it.

Because we are using fresh strawberries (which are about 92% water), there is no need to add any water.

Ingredients

  • Fresh strawberries

  • Glycerine

  • Preservative (I used benzyl alcohol)

Water to Glycerine Ratios

One of the most common ratios of water-to-glycerine for an extract with preservative is 50/50. It’s easy to work with too.

I generally start by seeing how much preservative is recommended, choose a dosage a little higher than middle, then calculate ‘backwards’ to find how much glycerine and strawberry to add. I used benzyl alcohol in this extract which has a recommended max dosage of 1%. But because glycerine is ‘aiding’ the preservative, I chose to use less than max: 0.6%. I made this pictured batch some years ago and it performed beautifully so if I were to repeat this today, I would use the same amounts.

Strawberry Glycerite with Preservative

Ingredient %
Preservative 0.6
Organic Strawberries 49.7
Glycerine 49.7

Method

  1. Sanitise the jar and equipment

  2. Place the jar on a scale and set to 0

  3. Slice or chop the strawberries

  4. Add strawberries to jar to desired weight

  5. Set scale to 0

  6. Weigh up glycerine to desired weight

  7. Weigh and add preservative

  8. Place lid on jar (TIP: If your lid isn’t in pristine condition, place a protective layer of food-safe paper or plastic between the lid and jar)

  9. Place jar out of direct sunlight at room temperature. I find putting a tea towel over the jar works well.

  10. Gently agitate the jar once a day for 7-10 days. The strawberries will start to look a little ‘spent’ and ‘tired’ when the mixture is ready for straining.

You Might be Wondering…

If we are using a preservative, can we add it after straining instead of before infusing?

Yes you can. To do so, weigh up the amount of strained liquid and then calculate how much preservative to add.

Why I don’t do it this way.

I prefer adding preservative at the beginning because the water to glycerine ratio is lower than when making a self-preserving glycerite (read: the preservative is working while the infusion is ongoing), and I just find it easier (and makes for less math) all around.

Straining

  1. Sanitise your equipment

  2. Place funnel in receptacle

  3. Place filter/ lining in funnel (1-2 layers of clean muslin, cheesecloth, or suitable paper filters)

  4. Pour mixture into funnel and allow to strain

  5. Decant into bottle

  6. Label and date the bottle

  7. Store the extract cool, and use within 6 months.
