Lauter Tun A modern type of Mash Tun which incorporates improved rake gear and is self-venting of the draff. Sugars are washed off the grist solids by elution.
Leaching (US term) One of the most common terms applied to the filtration process carried out in the production of Tennessee whisky. Also known as "Charcoal Mellowing" and the "Lincoln County Process".
Lincoln County Process See "Leaching".
Liquor Hot water used for the mashing process.
Lomond Still Peculiar column-shaped still with a refluxing coil in its head which enables the still to be "tuned" to produce a lighter or heavier spirit allowing a distillery to produce two distinctly different malts from the same set of stills. It works on the same principle as a normal pot still. Found at one time at a number of Hiram Walker (Balantine's) distilleries, it is now not in favour.
Lost Distillery A distillery which has been permenantly closed down and its buildings either demolished or converted for other purposes. There might just be a small stock of its whisky still available at a premium if it closed comparatively recently but stocks in the older lost distilleries will have become exhausted.
Lowlands One of the four whisky-producing regions of Scotland, the Lowlands is a region to the south of the "Highland Boundary Fault Line", roughly a line drawn between Dundee and Glasgow (see "Malt Whisky Regions Map" ). There are four main districts in the Lowlands Region :-
The Western Lowlands covering the distilleries around and to the north-west of Glasgow.
The Central Lowlands covering the distilleries between Glasgow and Edingurgh and north of there.
The Eastern Lowlands covering the distilleries to the east and south-east of Edinburgh.
The Borders covering the distilleries to the south of the region, bordering on England, around Girvan and Dumfries).
Traditionally, the triple distillation method which produces a lighter style of whisky was used in this region. Auchentoshan and Rosebank are examples of triple distilled whiskies; generally fragrant, floral whiskies with some fruity notes (compare with
"Islay", "Campbeltown" and "Highlands" region characteristics). An operational Lowland malt distillery is now a rare thing. Many have been closed down over the years. Rosebank and Bladnoch in 1993, Linlithgow in 1983, Inverleven in 1992, Kinclaith in 1975 and Ladyburn was only in production for roughly ten years . However, as the dividing line is geographic, some Lowlands distilleries near the "Highland Boundary Fault Line" show characteristics of the Highlands region and vice-versa.
Bladnoch reopened again and the first distillation was completed in 2000. Rosebank is also being brought back from oblivion, but has to be rebuild again, because the old distillery was stripped and demolished.
Low Wines The retained output of the distillation of the Wash in the Wash Still which is typically at about 15% alcohol by volume. The unretained part is sent to waste as it is just distilled water. Confusingly, in the US, this retained output is known as high wines.
Low Wines & Feints Charger The Low Wines and Feints Charger is a collecting vessel to collect the wanted output of the Wash Still (the alcoholic cut - the low wines) and the unwanted output from the Spirit Still (the first and last cuts - the foreshots and the feints) prior to them being passed into the Spirit Still for (re-)distillation. This vessel is sometimes known as the low wines receiver.
Low Wines or Spirit Still Traditionally, Scotch malt whisky is distilled in pot stills which are large, onion-shaped copper retorts used for distilling batches of malt whisky. The Low Wines or Spirit Still (sometimes called a doubler) is the still in which the second stage of double distillation (and third stage in triple distillation) takes place. Of the output, the first cut (the foreshots) and third cut (the feints) are returned to be re-distilled next time round and the second stage (the middle cut) goes forward to be casked-up to become malt whisky after maturation. The second (or third) chamber of the Spirit Safe is used to direct the flow to the appropriate destination.

LPA Litres of Pure Alcohol - the EU standard measurement of a distillery's capacity which is replacing the use of proof gallons. One proof gallon is 2.59 LPA. See "Proof".
Lyne Arm The part of a pot still extending from the top of the neck down to the Worm Tub or Condenser (sometimes called the lye pipe or swan neck). There is considerable variation in design of these and distilleries will vigorously defend their own design as contributing something unique to their final product.
