And considering that his calculations didn't account for the now repeatedly demonstrated principle that the majority of thujone is not recovered the distillate, no we can't.I used "didn't specify" to simplify this, "However, Arnold failed to mention the wide variations in the oil content of wormwood and the even wider variations of the thujone content in the oil...". Considering that they list variations that go up to the percentage used by Arnold, we can substitute his calculations for actual examples.
Arnold didn't use any wormwood (or absinthe), he used a calculator.
We can accept that his calculations of the thujone concentration in the primary macerate were more or less accurate, but that's where Arnold left off, before doing any practical research on the behavior of thujone during distillation. At least none that he's talking about.
I know this thread is 4 months old and I am not at all knowledgable in distillation but a simple observation must be made and hasn't been. Maybe it is just understood in this astute and calculating congregation.
1. Are the oil and thujone concentrations in A. absinthium the same today as they were 120 years ago?
2. Have deliberate farming and possibly genetically selecting seeds altered the end product? As we
have seen in other potentially "potent" crops.
