I got burned out on brewing because of a guy that wanted me to brew for him commercially, and then well he wanted everything on the cheap, and didn't want to do a proper brewery. Anyway I'm getting back to the point where I want to do some batches. I really was able to hone my skills and use some cool equipment ie Sabco Brew Magic. Now I am back on my batch sparge equipment and I am excited to start brewing again. I looked through all my ingredients and I have enough grain for at least 1 10 gallon batch maybe more. I have enough hops for a long time. Problem is everything is 4 years old including several refridgerated packs of S05. What would you do? Double the amount of hop pellets to make up for age. These are unopened big bags of pellets. Would you do a yeast starter with dry yeast to make sure there is anything living? Grain was in sealed totes still in their bags and smell good.
