The last stop of the Irish study tour for me was Teeling distillery. Most people went on to Whiplash brewery afterward but I had to meet my cousin's husband so on this occasion you won't get to see me acting like a maniac.
Teeling Distillery was built in 2015.
They have a wet mill and do single infusion mashes in a lauter tun at 66°C twice a day. Malt and pot still whiskey is made, the pot still being 50% raw barley with added alpha amylase and beta glucanase enymes.
A mix of distiller's yeast and white wine yeast is used for fermentation, along with lactobacillus and wild yeast.
A single brew fills the wash still which takes 8.5 to 9 hours to make the low wines at 30% ABV. Two wash runs fill the low wines still and one low wine run goes to the spirit still which comes out at 82% ABV. The stills are heated by external plate heat exchanges and the lyne arms have a 5° slope.
The new make spirit is cut to 66% ABV for barrel filling. In Ireland the barrels don't have to be made of oak. Losses are 5% in the first year (2% from filling), 3% each year after that and 2% on emptying. The whiskey is cut to 46% ABV for bottling and is not chill filtered.
