Infusion or Tincture

[Eckardt M]

Good day everyone, hope all is well and that some good Rum is being made.

I have a question on making a spiced Rum.

Is it better to make tinctures of various spice flavors and flavour the rum by adding a little bit of the tinctures to the rum or is it better to infuse the rum with the spices?

If the infusion is better how does one filter out all the unnecessary powder bits?

Why I am asking this is we have infused the spices with the rum. We filtered the spice rum through 1 coffee filter. The next day when one look through the bottle you can see some bits floating around in the rum. We have only used powdered spices, Cinnamon, ginger, nutmeg. We had to filter the spiced rum 4 time more to get everything out.

Your help will be appreciated.
