is there a reason the mash process should be closed lid other than to not lose any water vapour? im doing a lager and will be topping up after the first 30 of 90 min boil. to keep the temp somewhat constant i have the lid open a lot (for when i turn on the heat and stir and hold the bag off the bottom of the kettle). it's cold outside
