I've been doing extract for a bit over a year and just did my first partial mash brew ( 3.5 - 4 lbs grain in a 2 gal beverage cooler + extract) I did this with just a couple of steeping bags....it is in the fermenter bubbling away. Looking to future batches ( still. Partial boil limited by pot size and stove top...how should I go? 5 gal cooler and paint strainer? 5 gal cooler with stainless tube? Just the 2 gal cooler and paint strainer bags...???
