So I made and IPA with an OG of 1.080ish. It fermented fine. I used Wyeast 1272. After fermentation, I split the batch into two separate 3 gallon carboys to try different dry hops. Only the bottles from one carboy have carbonation. They have been in the bottles for close to two months now. That was probably my 10th batch, so I know how to mix the The first one carbed up in about a month. Maybe I didn't get enough yeast into the first carboy when I transfered. What can I do to fix it?
