To flavour schnapps, vodka or whatever base spirit you choose, you get the best result, if you use natural ingredients like...
...herbs, fruits, berries, nuts, spices, leaves, sprigs, roots, seeds, peels, blossoms, beans, pods, barks, etc.
Also, it does matter whether you use home-growns or plant material from the supermarket or local grocer.
Not that you get a bad schnapps or liqueur from commercially produced plants. Far from it. But a schnapps or liqueur based on home grown plants or plant parts is usually so much more aromatic and tastes better.
If you can't get home grown or wild plant material, it's a good idea to buy organic if available.
Very often it also matters whether your plant material comes from wild or cultivated plants.
Many wild herbs, fruits and berries have much stronger taste and aromas than cultivated ones.
So, whenever possible you should use wild edible plants or plant parts for your schnapps and liqueur making.
Wild plants grow in woods, heaths, field boundaries, dunes, meadows, hedgerows, wetlands, sandy areas, hillsides, etc. Some wild plants are easy to find.
Others you must look for - that's just part of the excitement.
Just remember... NEVER use plants or plant parts you don't know. Never!
They could be unhealthy or even poisonous. Use a plant identification guide or local flora to find out.
You can dry your plants or plant parts for later use.
Just be aware that plant flavours will either change, be more concentrated, or even disappear during the drying process.
This can be good. Or bad.
It all depends on what kind of flavoured schnapps or liqueur you want to make - and what suits your taste.
Some plant materials keep their colours and flavours better if you freeze them instead.
Just remember to defrost them in the spirit when you make your flavoured schnapps or liqueurs or they will loose too much of their flavours.
