Greetings fellow brewers, below is my first attempt at assembling a PM/BIAB recipe using BeerSmith2 (which is a completely awesome program...) This will be my fourth brew and the first departure from extract/specialty grain. I currently only have a 5 gallon kettle at my disposal (as well as a smaller 3 gallon) and the idea of conducting a partial mash/brew in a bag seemed like a great idea!

My beer will be a California Common. As a SF native I have drank up and down the entire Anchor offering (and done a tour of the brewery to boot!). I made an extract/specialty grain version which turned out delicious but after learning more I realized I underpitched my yeast, using just a single vial of White Labs CA common strain- no starter. I have since upped my game using starters for subsequent offerings.

What I am after with this common recipe is a crisp, almost golden to light amber beer, with a great hop aroma and mild bite. In an attempt to obtain this, half of my NB hops will be used later in the boil/flame out and the light DME is left to the last 20 minutes of the boil.

I think that I have the BIAB process dialed in on BeerSmith, although I am a little unsure. This will be a partial boil with a topoff at the end. According to beersmith, I will be topping of with a little over 2 gallons of water and then pitching my entire starter.

Thanks in advance! :mug:

You can heat up your oven. Most get to about 170 as the lowest temp, But you can heat it up. turn it off and place the pot in there. I do that for my partial mash brews and it holds temp perfectly. Always within one degree.
