Tracey, I tried to put together some homemade V8 juice, but just couldn't get the quantities of liquid from each item correct. Take for example the Beet Juice. Which kind of beet and how is that juice recovered/processed before it goes into the mix. There are a lot of recipes that can be had on line, but I haven't found one that details the individual components.
Try mixing some gin or vodka with a couple ounces of Margarita mix and then add the V-8 juice. With Vodka, I call it a "Moscow Maria". Cracked ice in a tall glass with a straw. It will take some peppery heat if you care to add some.
There are times when "Grandpa Teddy" needs a lot of "medicine".
