When it comes to vinyards a lot of them started selling grape juice. some even sold their grape juice with dire waring labels that explicitly noted the conditions under which the grape juice would ferment into wine.

Another loophole that allowed for the sale of actual wine, rather than grape juice, was that sacramental wine was exempt from the Volstead act. This resulted in everything from some rabbi's turning a blind eye to sacramental wine being sold off to a rush of hundreds of 'self ordained' rabbi's appearing in San Francisco. Apocryphally at the end of the 20s before this was cracked down on, rabbi's outnumbered jews two to one! http://www.jweekly.com/article/full/65526/then-and-now-prohibition-gave-shuls-license-to-pour-freely/ Although the home grape juice market and sacramental wines kept a lot of vintners running the lack of legitimate markets did drive a huge amount of them bankrupt and they were simply abandoned. For the last 15 years or so there's been a cottage industry in California rediscovering abandoned vineyards and putting them to work again. Zinfandel was a very popular grape in the late 1800s and was popular due to it's hardy vines and robust fruity taste. These 'old vines' from pre-prohibition are highly sought after. http://en.wikipedia.org/wiki/Old_vine#Old_vines_across_the_globe

Whiskey manufacturers found legal loopholes to be rebranded and licensed as 'medicinal' alcohol. In fact one of the greatest rise and fall stories from this era and inspiration for Jay Gatsby was a pharmacist called George Remus who could legally buy cases and cases of medicinal whisky and then have his own trucks hijacked so he could sell them on the back market! Despite this the industry was crippled during the period and didn't fully recover until after WW2

So I'm afraid they didn't "shut down and reopen" for the most part they shut down and never reopened. The ones that survived were the biggest breweries and distilleries that could retool themselves for 'health tonics' or medicine and weather the storm until 1933.
