Yes there has been a lot of work on histamine and other amines in wine
and cider in recent years. It brings an extra dimension to the hangover
story. As far as cider is concerned, much of the work has been in Spain
because of their relatively uncontrolled lactic fermentations during
cidermaking which are important for the Spanish flavour profile.

There is a good deal on fusels wrt different yeasts in Fred Beech's
review paper from 1972, at a time when the UK industry was moving away
from "wild" and "natural" to much more control.

I don't offhand know of any more recent work (unless there is some from
Spain again). The presence of phenylethanol and other fusels
pre-existing in the apple as glycosidic precursors was not known in the
1970's and only became apparent in the mid 1980's. There are at least 3
different biochemical routes to fusel alcohol production each of which
could be affected by many things. The route to methanol is different,
since it comes from pectin breakdown, but again there are many factors
which could influence that.
