    Dear Pedro,

    Your maths really caught my eyes. Congratulations on the wonderful post.

    Interesting numbers,

    So how does that translate into how many bottles of Port can be produced from an average vine at Q. Vale d’Agodinho?

      Andy, I will help Pedro with these numbers!!!

      - Quinta Vale d’Agodinho (QVA) has around 50,000 vines
      - it has an average production of 90 pipas, this is 67.5 tones, or 1.35 kg per vine
      - with 1.35 kg we can make around 1 liter of must
      - a bottle of Port has 80% of must and 20% of brandy
      - the brandy is not made with grapes from the QVA but obtained externally
      - so a vine at QVA can produce an average of 1.67 bottles of Port, excluding the brandy!

      Not much… these ladies think they are nobles…

    Hi there, nice blog! We were wondering if you could hel us…
    We are 4 students of the School of Economics and Management (UCP Lisbon) conducting our MSc. Dissertation.
    An important part of our work will be based on a Survey involving 400 UK consumers. In it, we ask questions about wine, in particular about Port Wine.
    This is the survey address:

    We would really appreciate it if you would participate it, and if possible, mention it.
    Thank you. Pedro
