This does not look like Aloe castilloniae, which has short, recurved leaves and sideways to downward growing stems. More likely a hybrid. I see a bit of in the mix, maybe. In any case, I would like to propose moving this image to the genus entry.

Aloes (Aloe)

Inviting the contributor and @ketsui73 to comment in case they know the name for this plant. The hybrids of castilloniae tend to be dominated by castilloniae (especially with regards to leaf shape) so I think it may actually be unrelated (except as a distant cousin).

Hello both
Nice plant
I agree with Baja that this is not aloe castillioniae and probably not a direct hybrid of it . The plant does not jump out as any of the most common named ones I have seen, but it can be difficult some times with the same hybrids showing quite different colours and forms depending on growing conditions.
There is quite a decent galleries here and on agaveville

I have many hybrids, some you ID quickly , others take a little longer and still others you never find out, so it's best to enjoy the guessing game and try not to worry too much about it 👍
