You can use cultivated strawberries, but the wild ones are much more tasteful and aromatic. So use them if you can.
BUT - if you decide to use cultivated strawberries it's important that you infuse them in vodka or other spirit that has an alcohol content of minimum 40% (80 proof).
That's because cultivated strawberries contain a lot of water that will dilute the alcohol content - and high alcohol content is necessary to extract the full taste and flavours from berries that contain much water.
Remember - the strawberries must be fully ripe when you pick them.
Direction:
Rinse the strawberries carefully.
Leave them to dry in the shadow - on paper towel.
If your berries are frozen - defrost them in the vodka.
Use a clean glass jar with tight-fitting lid.
Fill 1/2 - 2/3 of the jar with berries.
Fill up with clear, unflavoured vodka - 40% (80 proof).
Steep for 3-4 months in a dark place at room temperature, 18-20°C (64-68°F).
Shake lightly and taste it from time to time.
Strain and filter your infusion into a clean glass bottle or jar with tight-fitting lid.
You can serve your strawberry schnapps after it has settled for a couple of days. It has a fresh, fruity taste.
Or you can store (age) it for 4-6 months in a dark place at room temperature before serving.
The flavours will change rather much during storage. For the better I think. But it's a matter of taste.
Some prefer the fresh, fruity taste - others prefer their strawberry schnapps after shorter or longer storage.
Note: If for some reason you are not satisfied with your infusion, there are ways to adjust both taste and flavours - click here to see how.
Serve your strawberry schnapps at room temperature in suitable glasses. And remember to keep your schnapps bottle tightly closed and in a dark place before and between servings.
