Hey guus I'm planning on making a mango puree for a saison that I recently brewed. I was looking for recipes online and am having trouble finding recipes that involve boiling water. Is a boil necessary or would the beer be fine if I made a puree without heat to kill bacteria?
You probably don't need to. Just sanitize all the tools you use and freeze the fruits. And don't call me Gus.
Or go to Wallyworld and pick up some frozen ones. I have found when I make mango sorbet that it is actually isn't much difference in cost to buy the frozen over the fresh, and your sanitation issues are pretty much already taken care of.
Any particular reason you want to make a puree, rather than just using cut up/smushed mangoes? Making a puree might theoretically allow faster/more complete extraction of sugars and flavors, but I've never had issues with non-puree'd fruit. I have used canned purees, bur generally avoid them, because they seem to cause more racking problems than more solid fruit.
I've used quite a few different fruits, but not mangoes. My post was just wondering why the OP wanted to make a puree rather than just using the fruit.
Not sure if this helps but I just brewed a pawpaw cream ale. I froze the fruit for a good two weeks to help kill any wild yeast etc., pealed the skins off (while frozen makes it easier). Then I pasteurized them by adding a little water and heated them up to 170 degrees maintaining the temp for at least 20 minutes. As it was warming I separated the seeds from the flesh and mashed them with my hands (wearing nitrile gloves). Let it cool to room temp then added it to primary about 3 days in. Then I racked it on day 7, so far so good no unwanted funk and an awesome aroma and taste.
I use frozen fruits added to secondary. It works great, and I would assume mangoes would translate to a peach for amounts. I always start with one lb per gallon with fruit. Except raspberries, them bastards are potent.
Mostly, but not necessarily. But this is the point I was making to the comment that seemed to question organic and sanitary as being incongruous.
