Old public domain from Librivox "Brewing" by Alfred Chaston Chapman (1869 - 1932) https://librivox.org/brewing-by-alfred-chaston-chapman/
Welcome to the BA site, fbt. This book was written so long ago that I wonder how close it will come to current brewing methods and technology, but I downloaded it to give it a listen when I have 2.5 hours available. Have you listened to it yet? Enjoy your time on the site, and hang out here in the Homebrewing forum as long as you'd like.
