I realize it's probably too late to sour a pumpkin ale for this year. I was thinking about possibly making a 10 gallon batch though, having having 5 gallons un-soured this year, and then souring the other 5 for next year...
To be honest though, I'll probably split it into two batches because I think the sour recipe will be a bit different than the normal one. I may keep the recipe the same though, and just vary the amount of spice mix added to each one??? Either way, I'll probably split them up into two batches.
I was looking for some recipes and stumbled onto this thread...
