Notes

With over 25 lbs of grain, this grain bill likely pushes the limits of your mash tun. It's a good idea to have several pounds of light extract on hand in case you don't hit your numbers. Higher OG beers require a bit more oxygenation as they do not absorb oxygen as easily. You should also consider oxygenating twice, once at pitch, and once 12 hours later. For those without an oxygen tank, set a timer for 5 minutes and vigorously shake your fermenter to acheive desired aeration. If using oak chips: Soak the chips in bourbon while the beer is fermenting. When fermentation is mostly done, add the bourbon and oak to the beer.
