Craft Brewer Mashing Systems
Craft brewers use two types of systems in brewing. The first is the traditional "American" style mash/lauter and kettle combination and the other is the "European" style mash/kettle, lauter tun, and whirlpool combination.
Craft brewers throughout the United States and Canada commonly use combination mash/lauter vessel and kettle systems. The advantages of such a system are that it is simple to operate and costs less than other systems. Rice or corn cannot be used with this system; only sugar or some kind of pregelatinized extract can be used as an adjunct.
A combination mash/kettle, lauter tun, and whirlpool system allows for a more complicated brewing operation (Figure 9.3). The kettle becomes a multi-purpose vessel that is first used as a mash mixer and mash cooker. After mash-off, the mash is pumped to the lauter tun for sparging, and the kettle is quickly rinsed in preparation for the boil.
