One and a half tonnes of grist are transferred
to our stainless steel semi-lauter mash tun and three waters
are added, each one following at a higher temperature. The waters
dissolve the soluble sugars in the grist, creating a sugary water
called wort. The first two waters produce 7,500 litres of wort,
which are transferred to the wooden washbacks. The final water
produces a very weak, sugary wort, which is retained as the first
water of the next mashing. The grist residue, now known as draff,
is removed and used as animal feed. |
