Well, the alky presumably was shipped in full tanks / barrels /
whatever, so we can hope it's undiluted.

But, it is _very_ difficult (it takes some expensive chemistry tricks) to
get all of the water distilled out of alcohol, in other words, stronger than
around 98% alcohol. Is that all the alky producers go for, or do they use
the expensive tricks to get the last two percentage points of water out of
the alky?

It would be pointless as 100% alcohol would immediately start absorbing
water from the air.

In another post I said alcohol would absorb about 2-3% by volume. A web
search gives numbers in the range of 2-4%.
