You'll be able to learn about the following:

- Fermentation: The first step in creating any spirit involves fermenting grains or fruits with yeast. In this case, barley is typically used for whiskey production.

- Distillation: After fermentation comes distillation - this is when alcohol levels are increased and impurities are removed through heating and cooling processes.

- Aging: The final stage includes aging the distilled product in wooden barrels, which contributes significantly to its flavor profile over time before bottling takes place.

Island Distillers is another great option to explore. They produce vodka from Hawaiian honey and have plans for future whiskies. Whether you're a whiskey enthusiast or just looking for a unique activity, visiting a local distillery is a great way to spend a rainy day in Oahu.
