Good chance your BDSA took so long to carbonate because of the %ABV and not because of the cold crashing. How strong was the ABV?
Normal %ABV PAs and IPAs will carbonate just fine with 2-3 wks in the bottle even after 6 days of cold crashing. If you cold crashed for longer, say, a month or 2 then I would be more concerned.
My 9.2% RIS took 2 months to fully carbonate in the bottle.
Agreed
