Hey. There are a few pics of the 4 bags I sewed in the Beginner AG Forum under the topic - My First AG Adventure.
They are basically a fine mesh curtain material, cut into long rectangles, folded long ways, then sewed along the long edge and one end.
The top is folded back on itself to create a hole through which to pass some strong string.
They size about 60cm deep, and 25cm diameter. Each one holds about 2.5 to 3 kgs of grain and we use all 4 for a 50L brew.
This seemed usefull to start but sparging is difficult, as is squeezing the bags to strain all the liquid out. Definately requires 2 people. Also a pain to clean. Whinge, whinge, whinge...
Bought a metal mesh wastepaper bin this week to sit in the tun for the mash rather than the bags.
