Maintaining accurate sparge water temperatures can significantly improve the quality of your beer. By keeping water between approximately 75–78°C during sparging, you can maximise sugar extraction without overheating the grain bed.

The built in thermostat automatically cycles the heating element on and off to maintain your chosen temperature, while the keep warm function ensures hot liquor is always ready when required.

Constructed from high quality brushed stainless steel, the Keg Craft Sparge Water Heater is designed for years of reliable home brewing. The robust construction resists corrosion, is easy to clean and looks fantastic alongside any modern brewing setup.

The integrated sight glass lets you monitor water levels at a glance, while the large dispensing tap allows controlled filling of your mash tun or brewing system.

Whether you’re brewing a crisp lager, rich stout, hoppy IPA or classic bitter, having dedicated sparge water available makes the all grain brewing process smoother, more consistent and more enjoyable.
