To maximize extraction and minimize harmful oxidation of the mash, an AEGIR mash tun is built with the following features:
Grist hydrator with strike water to grist ratio programmable by recipe
- Bottom agitator to eliminate the possibility of contamination from above and a low shear blade to reduce oxidation of the mash
- Variable speed drive that allows adjustment to optimize agitator speed and minimize the chance of oxidation from this potential source
- Direct steam injection the allows rapid, optimum heating rate, minimizes energy input, eliminates possibility of burn-on that can occur with jacket heating
- Temperature control system that allows precise, automatic adherence to the brewing diagram for each recipe
