Yes, but as technique improved, there was less blood introduced on average and the pistachios would not be evenly coloured. To preserve the impression of quality, the farms then adopted the policy of wringing the worst performing worker of each batch of their blood to cover the batch in red homogeneously. This motivated improved performance batch on batch (less blood) and eventually, two workers had to be wrung, and at some point the remaining workers got so good that no blood was introduced and a drastic policy change had to take place.

That or automation.
They really should do an episode or How It’s Made on this. Super fascinating!
