Is possible to farm blood without killing the human?
Is it possible to store this blood for future drinking, and how long?

Is there any rules or lore book talking about it?

I'm new to WoD, so if you can provide sources allowing me to look for more details, please do.


It’s possible to store blood for later use.

Page 212 of the Vampire 5E core book discusses the difficulties of using bags of blood. If it comes from the hospital and has already been processed, then it can only be consumed by vampires with the Iron Gullet Merit. If it's raw, unprocessed blood in a bag, vampires of Blood Potency 2 can drink it and gain sustenance from it. It loses its Resonance after 15 minutes.

If you're drinking from stored blood regularly, you probably have the Bagger predator type (page 176), with all the benefits and drawbacks inherent thereto, including getting the Iron Gullet merit as part of the package.

You can safely draw blood using the Medicine skill.

  • \$\begingroup\$ Thank you. So it's not possible to store blood for a long period of time, is that correct ? \$\endgroup\$ – Dorian Turba Jul 13 '19 at 21:32

    \$\begingroup\$ @DorianTurba It can be stored in hospital conditions for a long time, but raw blood will clot and coagulate, eventually becoming unusable. \$\endgroup\$ – Jadasc Jul 13 '19 at 21:33

    \$\begingroup\$ @DorianTurba Yes. Of course, the Bagger predator type gets Iron Gullet as part of the deal. \$\endgroup\$ – Jadasc Jul 13 '19 at 21:55

    \$\begingroup\$ If you want real world data on storing blood, then blood for transfusions can be stored for 35 days (red blood cells): blood.co.uk/why-give-blood/demand-for-different-blood-types But a recent study says it is past its best after 21 days: telegraph.co.uk/news/health/9908613/… \$\endgroup\$ – DrBob Jul 14 '19 at 14:25

    \$\begingroup\$ @DorianTurba I think the correct paper is this one: ncbi.nlm.nih.gov/pmc/articles/PMC3744176 However, if you go onto Google Scholar and search for "blood storage times" you'll find lots of papers. Google Scholar is at: scholar.google.co.uk \$\endgroup\$ – DrBob Jul 15 '19 at 13:46
