Comment & Help Needed: What is Red Icewine?

[SN]

I recently receive a gift: a bottle of 1997 Pinot Noir Red Icewine made by Summerhill Estate Winery of B.C. Canada.

I previously thought that there is only white icewines. Would somebody tell me what red icewine is?

Should I keep it for a few more years or consume it right away?

Thanks for your help.
