Vat or VAT may refer to:
Synaptic vesicle membrane protein VAT-1 homolog is a protein that in humans is encoded by the VAT1 gene.
Synaptic vesicles are responsible for regulating the storage and release of neurotransmitters in the nerve terminal. The protein encoded by this gene is an abundant integral membrane protein of cholinergic synaptic vesicles and is thought to be involved in vesicular transport. It belongs to the quinone oxidoreductase subfamily of zinc-containing alcohol dehydrogenase proteins.
In melanocytic cells VAT1 gene expression may be regulated by MITF.
Vat 69 is a Scotch blended whisky created by William Sanderson & Son Limited of South Queensferry, Scotland, now part of Diageo. The whisky was at first bottled in port bottles.
William Sanderson was born in Leith, Scotland in 1839. He started an apprenticeship with a wine and spirituous liquors producer at the age of 13. By 1863, he already owned his own business producing liqueurs and whisky blends. In 1880, his son William Mark joined the business and persuaded his father to bottle various blends of whisky.
The iconic Vat 69 bottle with its bulbous neck was introduced to the market and was not changed for the next hundred years. In 1882, William Sanderson prepared one hundred casks of blended whisky and hired a panel of experts to taste them. The batch from the cask (or “vat”) with number 69 was judged to be the best, and this provided the whisky's brand name. The whisky was at first bottled in port bottles. In 1884, Sanderson bought the Glen Garioch distillery. It was situated in the middle of a barley field. The distillery was meant to ensure the delivery of grain whisky.
