If I recall correctly (it's been a long time) the smell was off-putting, but in the interests of science we pressed ahead. (Note: we. Something odd happens when teenage males gather, they loose 10% of their IQ for every additional one present.)
The taste ... now that did put us off.
For once we learned quickly. The experiment was not repeated. On reflection that might be considered bad science. We have to get a large sample set. Damn, that means I've got 99 more glasses of bhong water to drink.
