The reason folks recommend not running anything over 40% is for safety. If you have an issue with your boiler (leak,etc..) and it is filled with 40% low wines you now have flammable liquid all over…..If the low wines are under 40% or under you just has a bunch of wash to mop as under 40% is not flammable.
If you run the brandy again you might lose some of that great flavor- I’d personally just proof it down with some good distilled water.
When I do a stripping run I always collect everything- I run hot and fast and collect down to 10%.
