For the Partial Mash brewers, this is a tube of fabric that is 15cm in width and 75cm long.
Steep specialty grains at 67 degrees celcius for 20 - 30 minutes to add wort complexity and freshness, but use extract to provide the bulk of the fermentables. Partial Mash brewing is great for brewers limited space for large pieces of equipment, or Kit and Kilo brewers looking to get into entry level grain brewing.
Both ends are open for easy cleaning and can simply be tied closed while being used. Perfect for grain or hops
