Mash filter press

The best kept secret in the industry

Mash press filtration, the go-to lautering method for large scale breweries, is now available to craft brewers. A typical craft brewery uses a false bottom in their mash or lauter tun to filter the spent grains from the wort. While tried and true, this approach comes with some limitations. Every brewer has had to deal with a stuck mash when the false bottom clogs, especially true when brewing with grain bills high in adjuncts such as wheat, oats, or rye. This method of separation can also take an hour or more, extending your brew day and limiting your ability to double batch, and might achieve an extract efficiency of 85%.

Enter the mash press, the lautering method that was historically used up through the 16th century. Instead of relying on a gravity feed to drain the mash through your false bottom, the entire mash (grain and all) is pumped directly from the mash tun into the filter press. As the mash is pumped into the press, the inner chambers (between each pair of filter plates) fill to capacity. Once the chambers are full, the wort begins to pass through the fabric filters, capturing the spent grain and allowing the wort to continue on to the boil kettle. Once all of the mash is pumped through the filter, air pressure is used to inflate the internal bladders, squeezing the grain and removing nearly 100% of the liquid (and in some cases over 100%!)

OK, I'm listening...so what's the advantage?

Incorporating a mash press into your brewery has a lot of advantages over the use of a traditional false-bottom tun:

But what about...?

There are a number of questions we hear about the mash press from brewers. Let's take a look:

"Sounds industrial...is this really craft brewing?"

"More equipment sounds expensive."

"Squeezing my grain? What about tannins?"
