Every bottle in your collection. Every pour you've logged. Every tasting note you meant to remember but didn't. KillerBourbon keeps your whiskey collection and tasting journal in one place — organized, sharable, up to date. Built for collectors who take the shelf seriously. YOUR BUNKER Add bottles by search, barcode, or manual entry — or scan the label and let it do the typing. Track every bottle on its own: sealed, open, or finished. Record what you paid, where you found it, and how much is left. Add your own photos. Two of the same bottle stay two bottles, each with its own price, date, and fill level. THE TASTING JOURNAL Rate on a 0.0–10.0 scale and write the note while it's still in the glass. Pours are private by default — nothing is shared unless you choose to share it. Fill tracking updates as you pour, so you always know what's left. WHAT'S ON YOUR SHELF, AND WHAT IT'S WORTH See shelf pricing on catalog bottles alongside an editorial estimate of market value where we have one. It's a reference point for your own records, nothing is ever bought or sold in the app. STATS WORTH LOOKING AT Collection Score, average rating, pours logged, ounces poured, and how your bunker has grown over time. Filter by type, style, and characteristic — bourbon, rye, scotch, single barrel, bottled-in-bond, wheated and more. SPOT AND BE SPOTTED See an allocated bottle sitting on a shelf? Spot it so other bourbon hunters can find it. Spots record the store's location, and you can mark it still available or gone so others know. BRING YOUR PEOPLE Follow collectors, add friends, start a Group, and share what you're opening. Compare weeks on the Barrel Board with your circle. Create Group Tasting Events, sahre and rate the bottles at each tasting. FREE, AND WHAT'S NOT Pour (free) includes search and manual add, the full tasting journal, reviews, social, Groups, basic stats, and data export. Your data is yours; take it with you whenever you want. Barrel Proof adds AI label scanning, Bottle Match recommendations, unlimited bottles and lists, multi-photo and video, Shared Bunkers for collaborative collections, wishlist spot alerts, Hunt Mode, and the full Collection Score breakdown.
