Possible brewing uses could include: getting and keeping strike water at temp, direct use (with a filter bag in a mash tun or BIAB mash), maintaining temperature for sour mashes and getting to a boil more quickly (or helping to maintain a boil) for both all grain and extract batches. Contact the manufacturer with questions about suitability for your application.
I have a Sous Vide Cooker from Anova (completely different model). Check out my First Looks Post on that. Anova also has an article on their website about brewing with the Anova One.
