IMO I think you would be fine but I'm not 100% on this. I mean if you washed it if course it would be better but I've heard people brewing like this for barley wines all the time. I would say go for it.
Welcome to the community and the awesome hobby of home brewing. Your wife will learn to hate it lol. She will have created a monster lol. Welcome buddy! Enjoy yourself and have a blast.
My first years! Willamette, small cascade and 2 centennials. Not getting hopes up at all on comes but a few are growing nicely. Cheers. Any advice would be great
