In reflection this is one of the cheapest ways to make beer. holy ****. 4 pounds of grain: 5$ 1 packet of dry yeast: 1$, 1.5 ounces of hops: 2$, 2.5 gallon water jug +water: 2$, stopper 1.50$, 3 inches of air tube o.15$
2 gallons of beer + all the equipment to make it: 11.65$
Edited to add.
Oh I just realised you need a mashing tun too. But thats easy you can built a cheapy manifold from a stew pot:
copper tube 1$
syphoning tube 2 feet .50$
Cheapy themometer, 1:50
Cut the slots in the copper tube for drainage. Smash the end of it, attach the tube.
Something like this would be what? 65% effiency.
so roughy 15$ and a little know how. can make you 2 gallons of beer.
