We're broadcasting from Monday Night Brewing's Garage this week.  Does your homebrew blonde ale continually have an underripe apple taste? Or is there a rancid butter taste in your porter? Does your IPA taste more like band-aids than tropical hops?  This is the show for you. BJCP Grand Master beer judge Mike Castagno was an award-winning homebrewer before going pro at Decatur, GA's Twain's Brewpub. And BJCP Certified beer judge Nate Watkins is another award-winning prolific homebrewer. We talk about some of the mistakes homebrewers make, the off-flavors that can crop up, and how to fix them. We discuss some of the things you can do before you brew to minimize the risk of off-flavors as well as sharing some details on common off-flavors such as acetaldehyde, diacetyl, chlorophenol, fusel / alcoholic, DMS (dimethyl sulfide), esters, oxidation, and the much-dreaded skunking.  Mike and Nate also share some info on homebrew clubs and ways you can train your palate to recognize off-flavors.   Plus, we talk to Michael Lowenberg of Modern Hops about the upcoming Day of the Juice festival.See omnystudio.com/listener for privacy information.Thanks for listening to Beer Guys Radio!
