Made a Munich Helles 11 days ago, it just finished its diacetyl rest and I transferred to secondary. However while I may sure the secondary carboy would fit in my extra fridge for its lager period, I did not measure with the airlock! Can I just cover loosely with tinfoil? I left Carboy cap on, so only have to cover airlock hole.
