03A new cellar is empty, so paste a prompt that adds three bottles before you ask anything else.
Takeaway 4
04Drinking windows the connection returns are estimates, and storage and taste still decide when to open a bottle.
To connect Cellared to ChatGPT, create a Cellared account in the iPhone app, find Cellared in the ChatGPT app directory, choose Install plugin, then sign in on Cellared's website and pick the permissions you want to grant. The whole connection takes a few minutes. After that, you can ask ChatGPT about the bottles you actually own, such as what to open with dinner, how two vintages compare, or what you thought of the last bottle you poured.
This guide walks through each step, explains what each permission screen is asking, and shows how to avoid a common problem: connecting to an empty cellar and getting nothing useful back. If you want the short version with every capability listed, the Cellared in ChatGPT page has it. What follows is the longer walkthrough and the reasoning behind each choice.
Before you start: why a Cellared account comes before anything else
ChatGPT does not hold your wine collection. Your bottles, quantities, regions, tasting notes and ratings live in your Cellared account, and the ChatGPT connection reads from and writes to that account. That means the connection has nothing to work with until the account exists and contains at least a few bottles.
Download Cellared on iPhone and sign up. The free plan holds unlimited bottles, so you do not need a paid plan to connect. If you already have a cellar in the app, you are ready for step two. If you are starting from nothing, you can still connect, and step four covers how to fill the cellar from inside ChatGPT. You can also bring an existing list across with the CellarTracker import or a spreadsheet before you connect, which gives ChatGPT a real collection to reason about from the opening question.
A practical note on names. Several wine apps use the word cellar in their branding. The Cellared connection is the one listed as "Cellared, by Cellared, LLC" in the ChatGPT directory, with the description "Your cellar, in conversation." Confirm the publisher before you install anything that will see your collection.
Step one: find Cellared in the ChatGPT directory
Open ChatGPT and go to the app directory, search for Cellared, and choose Install plugin. OpenAI has changed its labels for connected tools over time, and its help center notes that the directory is now presented as a plugin directory, so your menu may say Apps or Plugins depending on your account. The listing is the same either way.
Installing adds Cellared to your available tools in ChatGPT. It does not yet give ChatGPT any access to your cellar. Access begins when you sign in to Cellared and approve it, which is the next step. OpenAI's help center describes the same pattern for connected apps in general: the provider's authorization screen lists the services and permissions requested, and ChatGPT may ask for approval before reading information or completing an action.

Step two: sign in on Cellared and choose permissions
When you start using Cellared in a conversation, ChatGPT sends you to Cellared's website to sign in. This is a standard sign-in flow built on OAuth, the authorization method the Model Context Protocol specification requires for protected servers. In practice, it means you sign in on Cellared's own page, Cellared issues an access token to ChatGPT, and ChatGPT never sees your Cellared password.
On the connection page you choose what the connection can do. The choices fall into two groups.
Reading. With read access, ChatGPT can search the bottles you own, compare vintages and the drinking windows Cellared calculates, explore pairings from your own bottles and saved tastings, and show your recent tastings and ratings. Access to your saved palate profile follows your plan.
Changing. With write access, and when you explicitly ask, ChatGPT can record an opening or undo one, save a 5-point rating and notes, add bottles, edit a bottle's quantity or region, and remove bottles from active inventory. If you would rather keep ChatGPT as an advisor that cannot change anything, leave write access off. You can change the choice later.
Starting with read access is a reasonable default for a collector with a large, carefully maintained inventory. Starting with write access makes sense if your cellar is empty or small and you want to build it by conversation. The privacy and permissions guide covers the tradeoffs in more detail.
Step three: check what you granted
Before you ask a real question, confirm the connection does what you expect. You can review or revoke permissions on the Cellared connection page at any time, and you can disconnect from inside ChatGPT too. OpenAI's help center explains that disconnecting an app stops future access through that account, and that it does not delete existing conversations or saved memories. Cellared's privacy policy says the same thing from its side: disconnecting prevents future connector access and does not undo changes you asked Cellared to save.
That second point matters when you use write access. If you ask ChatGPT to add three bottles and then disconnect, the three bottles remain in your cellar. They are your data, in your account. Disconnecting changes who can reach them next, and leaves what already happened as it was.
Step four: start with three bottles
A new cellar is empty, and an empty cellar gives a question like "what should I open tonight?" nothing to work with. The fix takes one message. Paste a prompt like this into ChatGPT, swapping in bottles you own:
Add these 3 bottles to my cellar: 2018 Ridge Monte Bello, 2016 Produttori del Barbaresco Barbaresco, 2020 Domaine Tempier Bandol Rouge. One bottle of each.
This needs write permission. Three bottles is enough to see how the connection behaves, and it takes less effort than typing details into a form. If ChatGPT asks a clarifying question about a bottle, such as which bottling or size you mean, answer it. A precise bottle gives a more useful answer later, because a drinking window depends on the specific wine and vintage, not on the producer name alone.
Once the bottles are in, try the questions the connection was built for:
"What from my cellar should I open with steak tonight, something younger?"
"Compare the calculated drinking windows Cellared returns for my Cabernet vintages."
"Show my recent tastings and ratings."
Each question draws on your own inventory. A general chat can name a style that suits steak. A connected one can name a bottle you can walk to, and say where that bottle sits in its calculated window. For more on asking this way, see what to open tonight from your wine cellar.
What the drinking windows mean
Every window the connection returns is an estimate. Cellared calculates it from the bottle using the Cellared Ageability Index (CAI), and the methodology page describes the inputs. A window is a range of years in which a wine is likely to taste its best, and a range is not a deadline.
Wine Spectator describes a drink window the same way: it suggests when a wine is likely to be at its best, it is based on a taster's experience with that type of wine, and you can adjust it for your own taste. The same publication notes that published ranges tend to be conservative, so you may enjoy a wine after the listed window. Storage changes the picture too. Heat speeds maturity, which means a bottle kept warm may be ready earlier than its window suggests. Treat the connection's answers as a well-informed starting point, then let the cork, the glass and your own palate settle the question. If you want to understand how heat shapes the decision, read how heat and humidity age your wine.
Troubleshooting a connection that returns nothing
Three problems can leave a new connection returning little.
The cellar is empty. The answer will be thin or absent. Add bottles as described above, then ask again.
Write access was left off. If ChatGPT cannot add a bottle, check the permissions on the Cellared connection page and grant write access if you want ChatGPT to change your cellar.
The wrong account is signed in. If you have more than one Cellared account, confirm which one you approved. The connection follows the account you signed in with.
If none of these applies, disconnect, reconnect, and run through the four steps again. Questions that stay unresolved can go to support@cellared.ai, and the team responds within one business day.
What ChatGPT will not do
Cellared does not buy or sell wine, in the app or through ChatGPT. The connection also does not change your cellar without your permission and your explicit request. It answers from your inventory and your saved tastings, and it labels drinking windows as estimates.
The best way to decide whether it earns a place in your routine is to run it for a week. Connect, add a few bottles, ask what to open on two or three real evenings, and record what you actually poured. If the answers match how you would have chosen, you saved time. If they surprise you, you learned something about the cellar you own. If you are still deciding between cellar tools in general, the best wine cellar apps guide lays out the options by collection size.
Keep your saved bottles and available drinking-window guidance together. Free Cellared accounts support unlimited saved bottles; estimates require sufficient bottle and vintage information.
