Some advice on a couple of brands

[curiousbridetobe]

I'm getting married in less than two weeks and my husband's family is Italian. We want to get good Italian wines, a friends of ours can get some wines for us on a discount. I was curious to know about some particular brands that she had mentioned, quality and reputation. The wines are:

Fontanassa Gavi di Gavi 97

Castelcosa Tocai 95

San Rustico Amarone 94

We weren't able to find them in wines stores we visited today, we're wondering if anyone has information on these?? Your advice is greatly appreciated!
