I have some local hops, which I found in an online herb and spice store and I don't even know their type. They were cheap so I decided to give them a try. I'm planning to brew a small batch and add them to boil at 60 min / 30 min / 15 min / 5 min and dry hop the rest to get the full bitterness/flavor/aroma. I don't know how they were kept/dried and they have a lot of leaves/branches which I tried to seperate mostly but still there are some micro grind pieces left in the bag. I'm concerned if they might contaminate or ruin the beer, although it's a small batch I don't want to risk it. Also if it works fine I will use them in my regular batches. So I came up with this idea, I can boil them in a hop bag for a couple of minutes, cool and add it to the bucket after it's done fermenting. My question is, will I still get the aroma or will it be lost in sterilization boil? Or is it safe to add them as they are? Will alcohol protect the beer from contamination? What do you guys suggest?
