I've been a chef for 15 years and have been brewing with my girlfriend for a much shorter period of time now. However I am intrigued by the idea of incorporating the culinary ingredients I am so familiar with into brewing. We decided on a stout with flaked barley to enhance the creaminess with vanilla beans. Living in NYS we have an abundance of maple syrup in the coming months, and we want to add it in as well, to both add apv, but also as a flavoring and aroma ingredient. My question is where do we add it? I was think 15 minutes before the end of boil.
