Malt as whisky material

 It's germinated dried barley. Malt whisky uses only malt without any other grains but almost all grain whisky contain malt in mash together with other grains because only malt has enzymes for converting starch in grain to sugar.

 Malt is dried and removed root just after germination to stop further growing up. Some malt is dried by peat and it makes peat flavor whisky.

 There are 2 type barley, 2-raw and 6-raw. 2-raw barley Malt has good balance of starch and enzyme for malt whisky. 6-raw barely Malt has more enzyme than starch. It can covert not only starch in Malt but also starch in other grains to sugar. It is used for grain whisky sometime.

 Rye malt is also used rarely for rye malt whisky.
