Every working bar has an inventory. Professional bars count theirs constantly — bottles weighed, levels checked, orders placed. Home bartenders usually track nothing at all. That's how you end up with three half-empty bottles of triple sec, a sweet vermouth that's been open for eight months, and no maraschino liqueur even though the recipe everyone wants calls for it.
The Bar Cabinet sits somewhere in between.
It's not a restaurant inventory system. It's not a spreadsheet. It's a working list of what's actually on your shelf.
Get the bottles in. Get the major mixers in. Add the rest over time.
That's the whole job.
What goes in the cabinet
Four kinds of things live in the Bar Cabinet.
Bottles
Spirits, liqueurs, vermouths, amari, bitters. If it comes in a bottle and shows up in a cocktail recipe, it probably belongs here.
Mixers & accoutrements
Juices, syrups, sodas, shrubs, oleos, tinctures. Some you'll buy. Some you'll make yourself.
Garnishes
Citrus, herbs, olives, cherries, salts, sugars. The most temporary part of the cabinet. Lemons come and go.
Glassware & tools
Coupes, rocks glasses, Nick & Nora glasses, julep cups, shakers, jiggers, strainers, peelers. The tools that make a drink possible.
Recipes reference all of these things, and the matching engine can use them. Tracking your tools and glassware lets The Bar Book know, for example, that you can't serve a julep if you don't own a julep cup.
Categories, not brands
The Bar Book does not need a perfect database of every bottle ever made.
It needs to know what the bottle is.
If you add Buffalo Trace and mark it as bourbon, The Bar Book can use it as bourbon. If you add a bottle from a local distillery and mark it as rye, it can use it as rye. If you add an orange liqueur, it knows where that fits.
That is what makes the cabinet flexible. You can add familiar bottles, obscure bottles, local bottles, and bottles The Bar Book has never heard of. As long as they are categorized correctly, they can still be used.
The same idea applies to mixers, syrups, garnishes, and accoutrements. Once The Bar Book understands what something is, it can use it throughout the rest of the app.
Building your cabinet
The first setup is the only part that feels like work.
You can add things manually as you use them. You can spend fifteen minutes walking through your shelf and entering everything at once. Or you can take photos of your bottles with the labels showing and use an AI assistant like ChatGPT or Claude to help identify what you have.
That is usually the fastest way to start.
Take a few photos. Let the assistant read the labels. Then use that list to build your cabinet. You still need to confirm the categories, but you are not starting from a blank page.
The goal is not to create a museum of your bar.
The goal is to give The Bar Book a useful picture of what is actually available.
Bottle levels
The Bar Cabinet tracks enough quantity to be useful without turning into inventory accounting.
A bottle can be full, half, low, or empty.
That gives you a way to mark the difference between a fresh bottle of gin, the last pour of Cointreau, and something that needs to be replaced. It also lets The Bar Book surface ingredients that are running low without asking you to measure every ounce.
This is the right level of detail for a home bar.
You do not need to know that you have 187 milliliters of Angostura bitters. You do need to know that your bottle is almost gone.
Mark the level honestly and move on. The cabinet should take seconds to update, not minutes.
Why the cabinet matters
The cabinet helps determine the shape of the rest of The Bar Book's abilities.
Once The Bar Book knows what you have, it can start helping you use it.
Let's say you add rye whiskey, sweet vermouth, Angostura bitters, and a lemon. The moment those ingredients are in your cabinet, The Bar Book can begin matching recipes against them. Some drinks become available immediately. Others become one ingredient away.
That is the practical purpose of the cabinet.
The more accurate your cabinet is, the more useful The Bar Book becomes.
The purpose of this chapter
Honest tracking, not perfect tracking
You do not need to catalog every dusty bottle you have owned for ten years.
Log the bottles you actually use. Log the syrups you actually make. Log the citrus when it is in the house and remove it when it is gone.
The cabinet is a working tool.
Treat it like the grocery list on your refrigerator. Its value comes from being current, not from being perfect.
Spend ten minutes adding your spirits. Spend another five minutes adding the mixers and syrups you keep around. Ignore glassware and tools for now if you want. Add them later when recipes start calling for them. Do not worry about garnishes until you make a drink and realize you are out of lemons.
By the end of your first week with The Bar Book, the cabinet should be taking shape. By the end of your first month, it should be genuinely useful. After that, it mostly takes care of itself.
