Project Goal: Wine Vault is a blockchain-powered platform that simplifies fine wine investing through tokenization

Think index investing (like S&P500) but for fine wines. You buy the token, Wine Vault takes care of the rest.

Project Info:

Wine Vault is a company that aims to simplify fine wine investing through a blockchain-powered, ETF-like wine fund. By utilizing blockchain technology, the company aims to lower transaction costs, improve accessibility, and increase market liquidity. Their goal is to make fine wines a top asset class for investors worldwide.

Wine Vault offers a unique digital stablecoin called CORK, which is fully collateralized by a diverse portfolio of fine wines. The value of each CORK token is tied to the market value of the collateralized wines, and as the value of the wines increases, so does the value of the CORK tokens.

Wine Vault offers its members the unique option to exchange their CORK tokens for NFTs representing specific wines in our cellar, allowing for targeted investments. By acquiring the NFT, you secure the wine at the current price while it remains stored safely with Wine Vault. You have the flexibility to sell your NFT at any time or choose to have the actual bottle delivered to your home. NFTs provide a convenient way to invest in particular wines, catering to your personal preferences and interests, while still benefiting from Wine Vault’s storage and expertise.

By investing in Wine Vault, investors can diversify their portfolio, benefit from expert knowledge in the fine wine market, and access rare or allocated wines that may not be available to individual collectors. Furthermore, the platform offers greater liquidity and convenience compared to building and managing a private wine collection.

The CORK tokens are tradable on multiple exchanges and can be bought directly from Wine Vault. The company also partners with LIV-EX to provide real-time data on market pricing for their wine portfolio.

Why invest in fine wines?

Fine wine investing offers a unique and rewarding opportunity for investors seeking to diversify their portfolio with a historically stable and high-performing asset class. With fine wines demonstrating an average annual return of 18% since 2004, investors can capitalize on this lucrative market while also benefiting from its tangible and luxurious nature. The increasing global demand for fine wines, coupled with climate change impacting production, creates a compelling case for investing in exceptional vintages now. Wine Vault harnesses blockchain technology to make fine wine investing easy, accessible, and transparent, ensuring you can fully embrace the potential of this promising asset class.

If you would have started to invest in the Liv-ex 1000 (the S&P 500 of wines) in January 2004 and made a $100 investment every month, today you would have $98 000. Would you have chosen to invest that same money in an index fund following the S&P 500, you’d have $34 000.

Oh great we have another real life investment opportunity here. Great job and welcome.

We had one in our 1st season #VersacBricksquad from @TuruGlobal where you get the opportunity to invest in real estate.

How is this going to work, I mean the packages involved? For instance #VBS fractionalized the real estate into bricks so you can be a fractional owner


Bienvenido a este S4, el proyecto que está presentando recuerdo haberlo visto hace sobre 2 años, anunciando la venta de su token, eran ustedes o es otro proyecto que se creo con anterioridad.

Hi, no Wine Vault is a completely new business. There are other types of wine projects but not any operating with a fund structure (at least to my knowledge).

Wine Vault operates as a “fine wine fund,” purchasing and occasionally selling wines. As the value of the wines appreciates, the portfolio’s value increases. The CORK token is backed by the wines held by Wine Vault but is not tied to any specific wine in the portfolio. However, CORK tokens can be used to purchase Wine Vault NFTs that represent specific wines.

For example, upon launching 200,000 CORK tokens at $1 each, the collateralized cellar value would be $200,000. As the wines’ prices increase, the collateral value rises, causing the value of the CORK tokens to grow.

The classification of wines as commodities (not securities) presents a unique opportunity to create an investment product like Wine Vault.

Wine investment is slept on and one of the best performing asset overtime irl, bringing wine investment into web3 is intriguing to say the least. As this isn’t my first encounter with this topic, I’d like to know;

How would the team outsource the wines to be stored in the cellar? From retailers or producers?

How will the team Incentivize users to continually use the platform?

How will the Wine Vault project ensure that investors receive returns through wine appreciation and price appreciation?


thank you so much for the explanation.

Hi @manfred_jr, thanks for the great questions!

How would the team outsource the wines to be stored in the cellar? From retailers or producers?
We collaborate with some of the world’s leading wine traders to source our wines. Our wines are either acquired 1. directly from the producer or 2. purchased from other traders or collectors.

  1. Approximately 60% of the wines in our current portfolio come directly from the producers. Having been in the business for almost a decade, we have established a solid relationship with top manufacturers and secured a significant amount of annual allocations. About 70% of the wines we buy directly from the producers are “En primeur” (a method of purchasing wines early while still in the barrel), while the remaining 30% consists of later vintages released by the producer.

  2. The remaining 40% mainly comprises later vintages that we buy from other investors and traders.

All wines are stored with professional trade houses to ensure proper storage and insurance.

How we incentivize users to continuously use the platform?

Wine Vault is designed as a set-and-forget platform, primarily focusing on managing a fund rather than relying on massive transaction volumes. CORK serves as an ETF-like investment instrument for those looking to diversify their investments into fine wines. As the value of the wines in our cellar appreciates, the token’s value increases as well. Similar to an ETF or any investment, many members have expressed interest in making monthly investments ($10, $100, or $1000 per month), and CORK enables us to easily implement such mechanisms.

How will the Wine Vault project ensure that investors receive returns through wine appreciation and price appreciation?

Our strategy involves integrating with the Liv-ex wine market API to provide token holders with real-time insights into the cellar’s market valuations. This enables members to determine if the portfolio is undervalued or overvalued compared to the token price. This data serves as the foundation for market-making and offers attractive arbitrage opportunities for interested parties. Arbitrage will be the natural mechanism for maintaining the token price’s stability.


Thanks for taking time out for explain, I can’t help but get excited reading through them. But I’ve further questions;

How will you incentivize users to continue investing in CORK after the initial investment? Will you offer any loyalty or referral programs, or provide any exclusive access or benefits to long-term investors?

How will you ensure the accuracy and reliability of market valuations provided through the Liv-ex wine market API? Will you conduct any independent audits or verification of the data?

Can you provide more information on how the arbitrage opportunities will work? How will you balance supply and demand to maintain the token price’s stability?


Thanks for the follow up questions!

REG your first question: I guess my point earlier was that token holders can be as active as they want. Some want to trade frequently, some just hodl. Fine wines are a great hedge for inflation so it obviously makes sense to buy early and then hodl as long as you can/want.

For the more active wine lovers we are creating the NFT product. This will allow members to buy out individual wines from the portfolio and keep them stored with WV until they are ready to drink. This is a great feature for e.g. restaurants. They can buy en primeur wines but don’t have to worry about storing them until they are ready to drink. Many top tier Bordeaux wines take 10 years to mature before they hit peak for serving and can be drinkable for 60 years.

Wine Vault also creates opportunities for individuals to create “sales businesses” on top of our platform. A member could check our cellar and start contacting restaurants to sell them the wines in advance and then just mint those bottles they’ve sold into NFTs.

We will have to think about different loyalty or referral programs - the business margins are very small with a fund like Wine Vault, but that was the whole point when creating it. Typically managed fine wine funds have large initial investment requirements ($1000 - $5000), an annual management fee (incl. storage and insurance) and they charge a 20% exit fee if you want to sell any of your holdings.

REG Accuracy of Liv-ex market API - Liv-ex is like the Bloomberg of fine wines, they sit on most market data and there isn’t anyone who can really compete with them. Their market data API is what every reputable trader / merchant uses so we will just have to follow the market here.

We will be introducing a cellar audit, to ensure Wine Vault actually sits with the wines it claims but that’s obviously not the same thing.

REG Arbitrage opportunity. In it’s simplicity, if you see that price of CORK (token price * supply) is lower than the total cellar valuation, there’s clearly an opportunity to buy a token that’s collateralized by more than it’s value. You buy the token and then you can sell it once the price goes up. Wine Vault keeps 15% of it’s assets in “money” in order to maintain liquidity, AKA to be able to “buy back” tokens if the CORK valuation drops and to be able to pay out to holders who want to sell their tokens. It’s a no brainer for WV to buy it’s undervalued tokens because it can re-introduce the supply later at a better market price.


Hola, tengo otra pregunta, si ustedes comercian directamente con los productores, cuando alguien quiere realizar la inversión se cual sea la cantidad, antes de invertir, ¿dispone de una catalogo de vinos?, ¿con toda la referencia a estos?. Ustedes comentan que compran vinos tempranos que están en barrica, ¿Se tiene en cuenta la añada de ese vino? Si fue muy buena, buena, regular, etc.

You invest in the CORK token - this is like a stable coin that’s backed with the whole cellar of Wine Vault. Market cap of token = total cellar value (when token is priced perfectly by the market).

We will provide a detailed list of every wine in the cellar with their individual values which allows you then to mint an NFT (at the cellar value) for a specific wine.

En primeur wines are already priced by the bottle but they just haven’t been bottled yet. This is like a “wine future” because even if wine critics have already scored the wines, their rating might still change as the wine continues to age in the barrel. When you buy En primeur you basically buy the bottles before they have been bottled.

Welcome to the TRON hackathon season 4 !
Very unique project !
I would like to know more about your wine storage. Will you provide more information of the trade houses ?
All the best for the product launch and hackathon !

We will publish a “cellar content list” on the new website which includes every bottle WV has and yes, we will also list the largest merchants. We don’t want to list everyone - it’s kind of a trade secret :slight_smile: These partnerships are a big part of the secret sauce.


Great to know that you will list that largest merchants ! And understandable that you don’t want to list every trade house. All the best for the hackathon !
