four Rousseau 800-liter French-oak mash tuns

Recommended Posts

Four open-top, 800-liter (211 gallons), French-oak mash tuns from Tonnellerie Rousseau are now available.  Have been used successfully for many malt and grain mashes, but they have been replaced with larger fermenters.


These are clean, water-tight and ready to be put to work in your mash house.  A full 1.5 inches thick with heavily galvanized hoops!

$3200.00 for all four, or 1000.00 per piece.  Ships from Dayton, Washington 99328.  Thoroughly shrink-wrapped and palletized prior to shipment.

Call 'The Proof Prof,' Rusty Figgins, and reserve these handsome mash vessels today!

Not just any barrels!  

Each is an 800-liter foudre, or also called a demi-muid.  They are made from 1-1/2" thick Limousin oak, the forest closely associated with the Cognac region.  They were custom-ordered in 2008 to be built without their heads for the express purpose of being used as mash tub. 

They were not fitted with valves or a bottom drain because the intention was to fill and evacuate each vessel  a using a racking wand, which always drained them completely after a slight tip to one side.  A quick rinse with very hot water, and a second evacuation makes them ready to use for the subsequent batch.   If you request it, the stock bungholes can be threaded to 1.5" NPT to accept a TC fitting, upon which you can install a racking cane and butterfly valve, but the point of an open-top fermenter is access from the top. 

As is commonly known, fermentations in contact with wood do not only have an esoteric appeal, they produce better flavors and aromas over stainless steel because of the presence of wood tannins.  Additionally, the same is true if used for fruit mashes. 

Each could be fitted with a drum dolly having a one-ton capacity, if mobility is desired.  They have always been used in stationary mode at two distilleries so far in their lifetime.  Lots of life left in these beauties!

Thank you for your interest, and all the very best,
