wort
/wəːt
/- St John's wort is an ancient herb, and was known to the Greeks and Romans as an astringent to be rubbed on wounds.
- As many might know, one of the worts' herbal properties is as a calmative.
- Purified water is first used to cool the boiled wort (the beer after boiling but before fermenting), becoming heated in the process.
- Waste heat recovered from the boiling kettle and from wort (unfermented beer) as it's cooled down is used to heat water for brewing and for cleaning the tanks.
- Instead, we recover heat from the boiling kettle and from wort [unfermented beer] as it's cooled down from boiling temperatures to fermentation temperatures.
Origin
Old English wyrt, of Germanic origin; related to root1.
root from Old English:
This is an Old English word related to Latin radix (see radical) and wort, which is used in the names of plants such as St John's wort. Root and branch, used to emphasize how thoroughly something is dealt with, goes back to the biblical book of Malachi: ‘The day cometh that shall burn them up…that it shall leave them neither root nor branch.’ See also money. Root used of an animal turning up the ground with its snout in search of food is a completely different word, that may ultimately be linked to Latin rodere ‘gnaw’ (see rodent). Someone backing a candidate for a post may be said to be rooting for them—perhaps with the idea of trying to dig up further support through their efforts.
