We recommend filling your mash vessel to no more than 75% of gross capacity. This will allow sufficient space for dough-in
and sparge arm. The chart at the end of the manual includes water to grist ratios for reference. The chart also recommends
lauter rates to reduce sticking the mash and provide consistency. A typical mash lauter should take 45-60 minutes. Also
included in the chart is the max recommended flow rates for RIMS or HERMS systems in the cart. Of course, each RIMS
and HERMS system and grist crush will affect flow rate, so you will likely need to experiment with your system.
The button louver false bottom is extremely resistant to plugging, however, most stuck mashes are usually the result of
drawing too hard on the mash, causing it to compact and reduce permeability. Too finely crushed malt and air in the mash
from raking too vigorously are the most common causes of a stuck mash. Additionally wheat, flaked barley, and oats are
particularly problematic due to lack of husks, higher protein and/or gluten content. Rice hulls are recommended for beers
with these ingredients.
Note:
You can use the level gauge as an indicator that the mash is beginning to stick. If the wort level in the level gauge
drops below half the height of the liquid level in the inside of the kettle, you are drawing too hard and should reduce the
lauter rate.
If you have stuck the mash, close the valve and gently scrape the compacted grains from the bottom of the mash. Allow ten
minutes for the air to dissipate from the mash then vorlauf (recirculate) until the wort clears. Then you may begin lautering
again at a reduced rate.
Optional HopBlocker
™
The HopBlocker™ is an optional accessory for the BoilerMaker™ brew kettle and is
intended for use as a hop and trub filter in the boil kettle ONLY. It is not suitable or
recommended as a mash screen. Please refer to the HopBlocker™ manual for
detailed instructions on use and installation.
Optional Mash False Bottom
The button louver false bottom (shown in Fig. 9) is an optional accessory for the BoilerMaker™ brew kettle and is intended for
use as a mash filter only. It is not suitable or recommended for use as a boil screen since it will impede the convective flow of
a full rolling boil and may lead to scorching of the wort. To install the false bottom, remove the dip tube. Place the false bottom
on the stepped bottom of the kettle with the “buttons” facing upward and the support feet down (
shown in Fig. 12
). Note that
the 7.5 &10 gallon false bottoms do not have support feet on the bottom. Install the large washer on the dip tube and place
the dip tube in the bulkhead fitting (
shown in Fig 13
). Position the hole in the false bottom close to the dip tube and rotate the
dip tube until it engages the hole, rotating the assembly into place (
shown in Fig. 14
). Push the dip tube into place and slide
the washer down to cover the hole (
shown in Fig. 15
).
