I suppose I could put a heating blanket in the tub with the fermenters, though I’m not sure about temperature control since the blanket has auto shutoff.Adding heat to a fermenter is tactically easier than removing heat.
Ask at that brewery, maybe they'll share some tips for a CDA? Likely have to go during the day to find the actual brewer.
As for the brewery that makes the delicious CDA, they’re a few hours drive northeast of us. I have looked at their website, which lists the malts and hops, though not in their respective proportions. There are guidelines to work with, so I’ll go the recipe builder route while trying to stay within those guidelines.
We are lucky to have The Bier Stein, a tap house and bottle shop that has an ever changing list of local and international beers on tap. Funny thing is I was hoping they would have a CDA on tap - I was in luck.
