I'm 54, and my wife bought me a brew kit 2-1/2 years ago. I was in school at the time, and way too busy to brew beer. So I would have to say 2 years ago. My first few batches were drinkable, but not great, so many more hours on HBT, and my beer has gotten much better. I just bottled 5 gallons of Taddy Porter, have 5 gallons of American Stout cold crashing, 5 gallons of Amber ESB finishing up and ready to cold crash, and a Strong Scotch Ale waiting for a spot in my fermentation chamber so I can brew it.
