Understanding Whiskey
Like Duolingo, but for Understanding Whiskey. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through In the Glass and At the Shelf and Bar. It starts from scratch.

Key ideas in Understanding Whiskey
- Keeping your mouth slightly open allows strong alcohol vapor to escape past your mouth instead of searing your nasal passages
- Deeply sniffing whiskey with a closed mouth pulls concentrated ethanol straight into the olfactory receptors, temporarily dulling your ability to smell
- A small initial sip coats the tongue and triggers saliva, buffering against the high alcohol content
- The first sip shocks unprimed taste buds, while subsequent sips reveal the whiskey's actual flavors instead of pure burn
- A few drops of water break the whiskey's surface tension, releasing volatile aromatic compounds into the air
- Water tones down the alcohol vapor barrier so subtle grain, fruit, or oak flavors become noticeable
- Ice numbs the tongue, while room-temperature water opens the aromas without chilling away flavor
- Aggressively swirling whiskey releases massive amounts of volatile ethanol, creating an intense vapor cloud at the rim
- Heavy ethanol fumes overpower the delicate barrel notes and grain flavors in the glass
- Coating the mouth and swallowing gently precedes the breath out
- Exhaling softly through your nose and mouth after swallowing drives aromas back up through the palate, showcasing lingering flavors rather than raw throat burn
- Gasping in air immediately after swallowing pulls ethanol fumes straight down the windpipe
- Bourbon must be distilled from at least 51% corn, providing inherent sweetness
- Aging in brand-new charred oak barrels imparts intense vanilla, caramel, and toasted wood flavors
- Other whiskey styles frequently reuse casks rather than using fresh charred oak
- Rye grain produces a peppery, spicy, and dry flavor profile
