Abstract: The invention relates to a system configured to monitor fermentation activity in a brewing vessel, the vessel comprising a gas internal region and a liquid internal region, in use, and a gasses outlet fluidly connecting the gas internal region to the environment, the system has one or more sensors configured to determine the level of the liquid region of the vessel; a gas flow sensor fluidly connected to the gasses outlet and configured to output a signal indicative of the mass or rate of gas flow though the gasses outlet; a controller configured to determine a change in specific gravity based on: the one or more sensors configured to determine the level of the liquid region of the vessel, the signal from the gas flow sensor, an initial specific gravity measurement; and wherein the controller is further configured to generate an output, display and/or store a fermentation activity signal based on the determined change in specific gravity.
