Soak them in water for a half hour or until plump. You could also soak them in elderberry wine to heighten those flavors before use. If you are putting them into a mash no rehydration would be needed (at least I think).biberbauer said:Since we're still in winter (I'm not an elderberry specialist, but I have a hunch the harvest was quite a while ago), do you think it might be possible to rehydrate dried elderberries? Is rehydration as simple as it sounds?
I shot an email to the owner/brewer of Otto's Pub & Brewery to ask him a few questions about how they use elderberries in making their brew. (Is that the pub you're referring to?)mdf191 said:I have had elderberries in several kinds of drinks. Elderberry stout being one of them. A local brew pub brews a batch every winter. The taste of the berries in their stout is very mild. I am not sure how much they use, but I think I would have a liberal hand if I used them.
