Thanks to my kids, I have a ton of marshmallows at the house that nobody is going to use. Anyone ever brewed with them? If so, what style and at what point in the brewing process? How do you account for them in your recipe ( in terms of sugar)? Thank you in advance.
They won’t add a lot of flavor in me experience. Marshmallow extract flavoring is all IU ever found that works.
No hands-on experience, but I listened to a podcast once (if they said it in a podcast, it must be true, right?) where they described brewing a marshmallow stout with real marshmallows. Expect them to expand and take forever to mix in when you add them to the hot wort – a big sticky mess IIRC – but it did work.

Recreate the experience, not the ingredients. You will get nothing from marshmallows.
Maybe if you toasted the marshmallows that toasted marshmallow flavor would be present? I think untoasted marshmallows would be like adding table sugar.
As are toasted. The main flavor in marshmallow is vanilla.
Article in Craft Beer & Brewing about exactly this. Consensus is that if you can deal with the mess they create with equipment then try them but as Denny said, mostly vanilla flavor is what you are really after.
Been seeing a lot of these around lately. Maybe look into weldwerks bubble wrap variants.
I was going to suggest vanilla.
Maybe prime with meadowfoam honey.
Seems like the general takeaway is big mess, low value. I’ll compost them. Thank you!

This is what I think about marshmallows in general anyway. They’re gross.
