Joaquin JimenezJordi Estapé Canal, and Mike Barrow, were in full representation of Openvino at the Barcelona Blockchain Breakfast, hosted by ctech.

Here is a good intro to the blockchain from the event for Catalan speakers.

Recently, Manuel Ponce Peñalva met with the CNV (Comisión Nacional de Valores) in Argentina to discuss the legality of our ICO. The response was positive, as the CNV does not see the MTB18 as a speculative token. We will continue to work with them as we move towards the "You Drink It, You Own It" security token. 

We have added (again) bitcoin as a payment method on

In the past we accepted BTC as payment in our shop (since 2015), but we had to change the payment module, because before we were using the module which now has a limitation of $100 USD transactions per day. 

We are still billing in Argentine Pesos (ARS), but can accept bitcoin as payment. This has a 


Today we successfully finished our first ICO crowdsale. We continue to sell tokens through for those etherless wine buyers, and this week, we plan to add ETH and BTC support to our shopping cart.

Also, we now have the MTB18 token icon registered on etherscan:

Final Token Numbers!

Yesterday evening we finished the final press, so we know the total amount of wine for the 2018 harvest. And therefore, we can calculate the number of available tokens.

Here is the breakdown:

The final tally is 12,570 litres of MTB 2018. We co-fermented the Malbec / Petit Verdot / Cabernet Sauvignon, so this is ALL the wine for the year.

12,570 bottles is the equivalent of 16,760 x  750ml bottles.

However, we expect to lose between 2-3% of this volume during bottling, and from breakages, etc.

So, we are going to issue 16348 tokens.

16348 is a nice number, because it is 2 to the 14th power. in: 1024 * 16

a very computable number, and easy to remember.

We will keep approximately 11,000 litres in one stainless steel tanks, with the remaining amount stored in oak barrels.

All the wine will be blended back together before bottling next year.

We are still working on the pricing breakdown, but this will be online at the time of the launch on Sunday.


We have 6 of our 7 videos online, and our animation, and they are beautiful!

El vino y las criptomonedas en la Universidad de Cuyo

La Diplomatura en Comunicación Digital y Trasmedia es un espacio de estudio, investigación y análisis de las tendencias en el mundo digital y los nuevos canales de comunicación con los usuarios. En el cursado participan tanto estudiantes de comunicación, diseño y cine, por nombrar algunos, como profesionales de la radio, la televisión y medios gráficos y online. Uno de los objetivos es acercar a los estudiantes a los referentes en distintos temas y por eso aceptamos con mucho entusiasmo la invitación a contarles de qué se trata Open Vino y conversar sobre criptodivisas, IoT, el marketing y la filosofía Open Source detrás de MTB.

Durante casi 2 horas nos sumergimos en las ideas, conceptos y expectativas sobre este experimiento que estamos llevando adelante. Los estudiantes mostraron muchísimo interés, realizaron preguntas y se mostraron curiosos porconocer más sobre este proyecto (!y participar de la ICO próxima!). Queda abierta la posibilidad de encontrar más articulaciones con el ámbito académico en Mendoza y en todo el mundo, por el interés que despiertan las cryptomonedas y por la posibilidad de seguir sumando colaboradores en este experimento.


I met many great people today at the Lydia Capital LATAM Blockchain Summit, held at the Algodon Winery estate in San Rafael and presented Openvino to the group.

Nice meeting this morning in Valladolid, discussing Openvino and innovations in Castilla y León. Interested startups, come to Valladolid!
