Thanks, it turned out ok, I could fit the grain and Mash water in ...pretty close to the top, just did not have space for the “Mash out” water, which I don’t usually bother with as any time I have tried it, it never seems to raise the overall mash temp to that higher range.
It was pretty close though today. Definitely taught me a lesson. I don’t brew big batches of big beers often enough to get a larger mash tun. If my older son did not want to split it with me I would have scaled it back down to 5 gal. I am really interested to see how it comes out, 9 different grains plus 7 oz of molasses. I guess it will be either really good.... or a dumper. It will be a beer to have when you are only having one though (abv around 8.5%), at least for me,
This is my third porter brew in the past couple of months so I think its time to change the channel after this one and try another style.
