I brewed my first all grain batch today with brew in a bag. Here is the recipe I used (Denny Conn's Vanilla Bourbon Porter):
This was a pretty heavy grain bill for 5 gallons, but I figured if my efficiency was terrible it would still turn out OK. Everything went surprisingly well. The bag held up, despite a LOT of weight, and didn't melt (I took an angle grinder to a camp grill to make a false bottom of sorts). My propane burner is a frikkin' upside down missile! I heated 8 gallons of tap water to 162 in 15 minutes! I ended up turning the stove all the way down, which was enough to maintain a full rolling boil. The IC worked great and was helped by a fair amount of ice in my garden hose.
Now, when it comes to efficiency, I came out at 53% with an OG of 1.065. Now the recipe calls for an OG of 1.092, but this is a porter so I'm pretty happy with what I came away with.
The only mishap was in raising the bag out of the pot. I constructed my bag like a pillowcase, which allowed the grain to form in one long tube when I picked it up. The ends of the bag spilled out over the kettle, and I lost probably half a gallon. So maybe that would put my efficiency in the 60-65% range, which is perfectly acceptable to me for BIAB.
Things I learned:
Sew the bag in a teardrop shape, so it drains from the bottom of the bag
Buy a decent lighter with an extended tube (lighting that thing takes nerves of steel)
Don't brew in 20F weather.
Plan better for grain absorption and evaporation (I lose a LOT up here in CO).
