Mountjoy prison officers seized a substantial amount of homemade alcohol or hooch, along with various other contraband items.
The jail’s operational support group uncovered the 60 litres of hooch fermenting behind radiators in cells and common areas of C wing yesterday.
Heroin, cannabis and 14 phones were also uncovered in the operation which was directed by intelligence gathered by prison staff.
All cells in C Wing are single occupancy, meaning the prisoners cannot deny owning the contraband items.
Prison officers say that the search got underway at 7am yesterday and that the inmates caught red handed will be internally disciplined within the jail.
As well as the 60 litres of hooch, officers seized: 14 mobile phones, 19.5g of cannabis resin, 19g of herbal cannabis, 6 sim cards, 11 chargers, 21.5 g of heroin and 421 assorted tablets.
Prison hooch is simple to make using fruits or fruit juices, sugar and bread; the concoction is usually brewed in plastic bags or cups.
The haul is the biggest since 30 mobile phones, modems and a number of USB keys were seized in Portlaoise Prison in August.
