Summerfield (California)

[On_The_Pond]

My daughter is getting married in May and the caterer's house wine she is pushing is "Summerfield" (not the expensive Summerfield from Australia, but a California version from I believe St. Helena area). I've found a couple references to the California Summerfield and it seems to run about $5-6 a bottle regardless of variety (so far I've only run across a merlot and a chardonay). If I buy my own wine they charge me a $15 corkage fee. Money is an issue, but I also don't want to serve terrible wine at the reception. Has anyone run across Summerfield and have an opimion? I can't find it locally (Indiana) and need some advice as I have to commit shortly. Thanks in advance.
