Certainly possible...
Roaring Forties:
"All Roaring Forties Products are made from 100% cane or grain, and have no preservatives, chemicals or artificial flavours added.
Absolutely no whey alcohol is used in the production of any of our spirits. Our methods are all of a traditional nature, which produce a high quality spirit, fit for the "Roaring Forties" label.
All aged products are stored in oak casks for flavour and maturation. "
Age not specified, but a clear statement of purity. I'd love to try this one, especially as it was made by da'rums buddies. Perhaps he's had a taste?
Koloa:
Koloa cites only double pot stilling (standard pot still procedure), but no mention re additives or not, nor of aging. Turkey shoot.
Wild Days:
"The molasses is fermented for 2 - 3 months, slowly converting the natural sugars in the molasses into alcohol. "This wash is then distilled, first in a pot still to keep the natural flavours of the brew, then reflux distilled to produce a high purity alcohol at approximately 90 per cent alcohol. The alcohol is immersed in activated charcoal, then filtered through heavier charcoal. Finally the finished product is put in French Oak barrels to age.
Our rum sits and waits in a temperature controlled environment, slowly getting better. When it is ready for bottling, we add oak chips to every bottle, to have the aging process continue right through till you open the bottle."
This sounds quite experimental. Oak chips is a daring move, and runs the risk of over-oaking (but remains to be seen). The fermentation is amazingly long, which adds many flavors, but which are partially removed by the distillation (to 90%) and moreso by the double charcoal filtering. Additives are neither confirmed nor denied, and the actual age (or type of oak) is not identified. A turkey shoot.
