Just went out today myself and got 2 metres of a polyester material that is probably the wrong stuff and spent an afternoon ineptly sewing it into a pillow case shape. Why?? Next time (or when the damn thing breaks) I will certainly go for one of these.

Edit: The ebay link will eventually go dead, but the sale is for "Huge mashing and sparging bag home brew beer" and the seller will post worldwide.

For the record, I think I used polyester charmeuse instead of voile. It does the job but drains rather slowly.

I haven't had the greatest success so far but I am still loving the brew bag. It definitely lowers the barrier to all grain brewing/stilling.

I am using the same boiler to mash and distil, but I suppose if I was being really lazy I could ferment in it as well! I guess a stainless boiler would be better suited than my copper though.

The damn thing duly broke when my flaked barley mash wouldn't drain, so I made a new one. I didn't buy one because I wanted it to be gigantic rather than merely huge.

The material I used was for net curtains and was called "Sue". It is 100% polyester with a weighted hem on the bottom, which made it easier to sew up, and a "slot pocket" on the top through which a draw string could be threaded. 48 inch fabric cost me 2 GBP per metre.

Used it once so far and very happy with it.

i have 2 more loads of flaked barley--- the first mash had to be squeezed by hand because the grain bag clogged. now i will try my modified mash tun. if it works and the wort is cloudy i cal always allow it to settle or use super clear.

Yes I had to squeeze the flaked barley too. I found it helpful to cinch the bag with a triclamp. Cloudy wort is fine to ferment I reckon.

:doh:I made a mistake here, i forgot that it was to be fermented next. It will be fine . A little cloudy might even be better for fermenting.----I was thinking of going right to distilling with the cloudy liquid-- After fermentation a bit of settling and racking will do the trick before distilling. :mg:

Do you do anything to sanitise the wash after all the mucking with it mate?

Sounds like a rife plot for infections. :?

I figure it's not necessary as long as you mash out to a high enough temperature.

Well I guess I figured wrong because I got what looked like a lactic infection after 4 days. The yeast had already gone dormant. It was a flaked barley/malt mash and I had presoured the barley with L. acidophilus. Hmmm.

WHEN I DONT WANT TO DISTILL RIGH AWAY, i treat the fermented liquid the same way i do a wine. i add potassium sorbate and sodium metabisulfat at the prescribed rates and just tag it and leave it in the sealed carboy. i have done this many times.


I believe that mashing out is just to denature the enzymes and whateve if you are making beer---i dont make beer so what i do may not be good for the beer taste.

i dont have a clue there :(
