The trick to an efficient and easy mash is the right equipment. I suggest using those 10gal GOTT or Igloo water coolers you can buy at Home Depot, Lowes, etc or just buy the ‘kit’ that can be found at home-brewing supply stores.
As for the extract ‘twang,’ you’re right about that and was the reason why I moved away from extract after my second batch. Mini-mash is a good in-between but to be honest, it’s not that big of a leap to a Decoction Mash.
I did not start off kegging at first, that’s the main advise I give to people looking to start brewing. The initial up-front cost of kegging is well worth the hassle and flexibility using kegs, especially if you have a dedicated fridge/freezer to dispense. BTW, look for something call “The Carbonator” which is a cap you can use with all soda PET screw-cap soda bottles. This is a great way to take beer with you from your kegs to a friend’s house.
Cheers.....
Oh I forgot about the Carbonator! I have had several occasions where Ive taken growlers that go flat quickly, I need to get a counter pressure bottle filler for that though. I do have my cooler/ mash tun but I dont have the room to get my AG system set up yet, so partial mash is it for now. My neighbor still manages to enjoy a good portion of my beer though!!
