My plan for my 10 gallon barrel is Old Ale, Barley Wine, Quad, Flanders Red, then Lambic, Lambic, Lambic. I plan on getting at least 3 clean beers out of it then souring the barrel and using it for an extended time.
I had a full size whiskey barrel that had a crack/leak so I could not use it for aging beer. I broke it apart and saved all the wood. I made tap handles with some of the staves, I made two plaques (awards) for my local homebrew club from the top. I used more of the staves in the smoker. I cut up some staves into cubes and gave them to fellow brewers as a gift/grab bag item. I used some of the cubes in my own beers (oak aged oatmeal stout was delicious). I still have some staves left so I may have to come up with some other ideas.
