Robert Scott "Wino" Weinrich (born September 28, 1961 is a doom metal guitarist and vocalist. Active since 1976, when he started his first band War Horse, Wino is best known for being the frontman and guitarist of the influential doom metal bands The Obsessed and Saint Vitus. His raw and deep vocals in Saint Vitus, as well as his guitar work in The Obsessed and his projects Spirit Caravan and The Hidden Hand, made him a big personality in the metal scene and one of the most influential vocalists/guitarists in the doom metal genre overall. Wino is also a solo artist, having released Punctuated Equilibrium in 2009.

Wino contributed vocals and guitars on the track "The Emerald Law" for Dave Grohl's project, Probot. He can be seen playing guitar in the Probot video for "Shake Your Blood," which features Lemmy on bass and vocals. He has also collaborated with ex-Death SS guitarist Paul Chain for some of his solo work. Wino was also the frontman for Lost Breed for a short time, a collection of recordings of this line-up has since been released, titled 'Wino Daze'. Wino worked with Black Sabbath bassist Geezer Butler, Sabbath drummer Bill Ward, Fight guitarist Brian Tilse and Judas Priest vocalist Rob Halford in the band Bullring Brummies, who are featured on the Nativity in Black Black Sabbath tribute album. He also played guitar on a demo for the band "Gypsy Moth" and can be found singing and playing on the Mystick Krewe of Clearlight split CD with Acid King. Both The Obsessed and Spirit Caravan have released anthology-type albums featuring rare tracks, Incarnate (1999) and The Last Embrace (2004) respectively.

Since 2009, Wino has been touring with the reunited Saint Vitus. New material from the band is a possibility, but so far, there are no concrete plans. If any new material is released, it would be Saint Vitus' first since 1995's Die Healing and its first release with Wino since 1989's V. Currently, Wino can be seen touring the world with his new band Shrinebuilder. The band's origins were established in 2006 when Wino contacted Al Cisneros and proposed that they form a collaborative band. They enlisted Neurosis frontman Scott Kelly on guitar and Al's drumming partner from Om Chris Hakius on drums.

As time passed word and anticipation began to gather about this newly proposed supergroup via internet blogs/forums. Shrinebuilder were a well known collective entity yet nothing had been heard regarding the act. In early 2008 drummer Chris Hakius decided to retire from playing music and as a result the Melvins' Dale Crover was drafted in to replace him. Over the next year the band continued refining their material and rehearsed in various configurations in Baltimore, San Francisco, Ashland and Los Angeles.
