The problem with a manual coffee shelf

If you drink specialty coffee, you have more bags than you should. There's the new arrival from last week, the half-finished comp pack you opened on Tuesday, two single-origins from a subscription, and a competition lot you're saving for the weekend. Half of them are aging without you noticing. The other half — you can't remember the roast date because it was on a sticker you peeled off when you decanted.

A spreadsheet would work for two weeks. A Notes app might last a month. Neither survives the chaos of actually using the coffees daily.

What inventory tracking actually looks like

• Visual rings. Every bag has a ring that visualises remaining weight. A full bag is a complete arc; a near-empty one is a thin sliver. The ring turns red under 40 g — a glance tells you what's about to run out.
• Automatic deduction. Log a brew with a 17 g dose? Seventeen grams come off the bag automatically. You never key in remaining weight manually.
• Days off roast. Set the roast date once. The bag carries it forever. Days-off-roast updates daily so you can see what's freshest and what's past its window.
• AI bag scanning. Point the camera at the label — name, roaster, origin, process, variety, tasting notes auto-fill. New bag added in under five seconds.
• Origin + process metadata. Every bag carries the data that lets Insights group by country, process (washed, natural, anaerobic), variety (geisha, bourbon, sl-28), and altitude.

How AI bag scanning works

Modern specialty bags carry a lot of structured information — name, roaster, origin, farm, variety, process, roast date, tasting notes. Typing all of it in for every bag is the main reason most coffee tracking apps get abandoned within a month.

HomeBarista uses on-device vision plus a coffee-specific model. Hold the bag up, the camera reads the label, and the new-coffee form arrives pre-filled. You confirm or edit, then save. The first time you try it on a bag with a complicated cooperative name and a six-line tasting note, the time saved sells the feature.

The brewing connection

Inventory only matters when it's connected to brewing. HomeBarista links every brew to the specific bag it came from — so the brew log shows which coffee was used, and the bag shows every brew it produced.

That connection enables a few things:

• Cost per cup, accurately. Set the bag price once. Every brew computes its cost from dose × (price ÷ bag weight). Insights show your monthly coffee spend and average cost per cup.
• Reference brews per coffee. Mark the brew that nailed a coffee as the reference. Next time you brew that bag, you start from the recipe that already worked.
• Days-off-roast vs. score. Over time, the data shows you the window where each style of coffee peaks for your palate.

Frequently asked questions

Is there an app to track my coffee bags?

Yes — HomeBarista. Every bag tracked with visual rings, automatic dose deduction, days off roast, and AI scanning to auto-fill bag details. Free on iOS.

How does coffee inventory tracking work?

When you log a brew, the dose is deducted from the selected bag automatically. The visual ring updates instantly. No manual updates needed.

How does AI coffee bag scanning work?

Point your iPhone at the bag's label. HomeBarista's AI reads the printed text and auto-fills name, roaster, origin, process, variety, and tasting notes.

Can I track multiple coffee bags at once?

Yes — unlimited on PRO. Each bag appears on the Coffees tab with its remaining-weight ring. The free tier supports a smaller limit.

Does the app track when coffee is going stale?

Yes. Days off roast updates daily from the recorded roast date. Most light roasts peak 7–21 days off roast; HomeBarista shows the current age on every bag.
