I thought I'd use the hive mind for this question -
We have a client that wants a very specific blend of our rums. It is 97% fresh column rum and 3% rum aged 3 years. The resulting blend has a very nice aroma and flavor profile that they approved, but after approval, they asked if we can de-color as it does have a yellow-gold color. Well, the client is always right so...
We used our activated carbon filter and gravity filtered the blend. It took 3 passes, but the resulting liquid was as clear as water (and very smooth). While the customer was happy with the transparency, they did not approve the sample because the aromas changed (well....duh!)
Anyhow, any ideas on how to filter out color without changing aroma? Or, how to add the aromas back in? We are going to do a rum essence of the aged rum in our rotovap to see if we can dose the aroma and flavors back into the filtered spirit....I don't have high hopes for that approach, but have to try.
Any other ideas?
Thanks!
