Alright homebrewers, i'v done 4 extract batches and i want to start all grain. I can't decide if i want to go with a 3 tier gravity fed with a cooler mash tun or a single tier with a kettle mash tun. I have been researching pros and cons of both but can't decide. I don't want to go with one and wish i went with the other. I have not brewed all grain on any system before. I'm just looking for some feed back from more experienced brewers. The summer is only so long in NEPA. Thank you in advance.
