It’s fall in Queens, and I could brew something at 50-60 degrees in my garage. Any recommendations on a recipe that makes a good beer at that temperature?
Any recipe could be good in that temperature range. It would depend on the yeast used, not the recipe. Nottingham dry yeast works good (and clean) down to about 55F. Look at the temperature range of the yeast you want to use. Hint: It is much easier (and cheaper) to raise the fermentation temperature a few degrees than to cool it. No refrigerator needed, maybe an aquarium heater to warm it just a bit.
I'll add I've had good results every time with common yeasts like Safale 05 US Ale and 04 English Ale, both down to 50 ambient temp with no extra equipment. Since you might see those for sale most commonly.
Since any recipe will do, this is what I am brewing this weekend, I just did the math today so it is at my fingertips. It's (ahem) a "smaller" 5% ABV adaptation of "Putin is a d#*@" from Pravda brewery.
