Looks like it could be AQ-1 since the panicle is longer than usual.
It's hard to tell, a lot of suppliers sell regular Aquatica clones as AQ-1
When I grew AQ-1 there was purple on the flower, too.
That is common for Phalaris though.
I've had pretty good brews from purple-tinged grass.

"...From a morphological point of view its
characters are included in the variability limits of the species [cf. Baldini 1993], apart from the
panicle tending to be a little longer at the plant maturity. However, its habitat is quite particular
AQ1 is in fact widespread on the calanchi, that is big furrows dug by the eroding water on clay hill
soils, in general showing a very typical and interesting flora."
Panicle-A panicle is a much-branched inflorescence. ... The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth.
