Irish Stout Partial Mash

[gpx]

Just finished an Irish stout partial mash comprising of 1/2 grain and 1/2 extract kit, realised I mashed the roasted barley for too long, around an hour. Will the beer be too acrid/bitter?
Cheers

Ok well it’s going to be however it is, but that kit was designed to be made up with a plain fermentable like sugar or malt extract. To do it with a partial mash you only needed base malt no extra flavour.

Mashing the roast barley with the rest of the grain won’t be the issue if it is too strong in taste.
