I’ve made a tincture with fresh ripe berries as well, and in that case I simply filled my jar with berries, then filled it with alcohol. I believe I used brandy as well.

Take a clean glass jar, -
I use honey or jam-type jars.

Fill it half-full(ish)with dried berries.Cover the berries with high-quality spirit, eg. brandy. Cap.

The jar will look to be be about 2/3rds full now.

Set to steep somewhere. Keep an eye on it.

The first few days, those dried berries will
swell as they re-absorb moisture, and you may need to add more spirit to keep ‘em covered.

Just keep them covered, and leave as long as you like.

After a month or two, the tincture should be usable. You might then decant the fluid.

It may improve with age + longer steeping, I don’t know.

It is not a highly – specialized nor regulated process.

Some folks like to do the berry extraction using a red wine.

I recall a Scottish doctor writing about the heart patients whom he kept alive into their 90’s, using only the tincture of the hawthorn berry.

He followed, of course, in the footsteps of many a wise healer; and I recall that it was a Doctor Greene, of Ennis in Ireland whose many famous cures popularised it’s use in more modern times.

Berry Good Health!
