For what it is worth, my small batch story:
I started brewing back in the late 1970s. Bought a book and plastic trash bin to ferment in and a few brewing equipment things I found a 5 gallon glass Alhambra water bottle and used mostly what was available in the kitchen to make extract brews. A few turned out good; several had weird flavors I did not like. We did not understand sanitation well. The bad flavors discouraged me and I quit brewing. Over the years I expressed to my wife that I would like to buy some better equipment and try this again.
Fast forward 40 years. SWMBO bought me a small batch brewing kit from
Man Crates last Christmas. The Centennial SMASH turned out great. The yeast is US-05 for anyone that ends up here searching for that tidbit. After brewing the first batch I started researching small batch brewing on the interwebs, including this thread, and decided to try a BIAB second batch. It turned out good and I tried some more. Feeling adventurous I found a 28 barrel (882 gallon)
Double Brown recipe from Biess and scaled it down to 1 gallon. It worked! I made 9 small batch beers before stepping up to 4 gallon batches using my old 5 gallon glass carboy. I’m 13 finished batches in and have not had a bad one yet. The small batches gave me a lot of experience while producing a volume of beer that I could drink without spending a lot on ingredients. I think I will cut back on batch size from 4 gallons because I don’t need several cases of beer lying around waiting for me to drink them. That is just me.
With planning I can use the carboy that came with the kit to make a 1.3 gallon batch which equals 2 six packs. My next brew attempt will be to make a 1.3 gallon California Common using methods described in this
Warm Fermented Lager thread. I will then use the yeast from that to pitch into a 2.5 gallon Doppelbock. Small batch is good for me.
Here is my small batch version of the Briess Good Humans double brown recipe that I like. It is stepped up and might better be described as a Baltic Porter (8-9%). I got 8% and was unable to get it to dry out as much as the recipe calculator predicted.
Double Brown Trouble
LB
3 2 row pale malt
.6 brown malt 70L
.4 Vienna 3.5L
.4 Munich 10L
.2 Briess Victory Malt 25L
.1 Caramel Malt 80L
.05 Black Malt 500L (Used Black Barley)
Grams
5.67 Amarillo (8% AA) Pellets 60 min
8.5 Willamette (4.8% AA) Pellets 30 min
8.5 Cascade (6.6% AA) Flame out
8.5 Willamette (4.8% AA) Flame out
Procedures:
9½ quarts water heat to 164º. Add 4.75 LB malt bill (I use a bag). Mash at 156ºF for 75 min (maybe mash lower for better attenuation and I think 1 hour mash would be fine). Drain and squeeze the bag. 9 quarts wort into 60 minute boil. 1.5 gallons post boil – cool to 70º. 1.3 gallon into fermenter. 1 gallon into secondary. (I would skip the secondary now.) Adjust starting mash water volume according to your equipment to end up with 1.5 gallons post boil.
