We buy most of our wine online so am out of touch with what is good from supermarkets. Going to friends for supper tomorrow, asked what colour wine they'd like us to take and was told white matches the first two courses - with the added info that one of the hosts only likes Sauvignon Blanc. We don't have any in our current box of wines. Due to a pretty full day tomorrow, the only supermarket I can get to is Tesco. I could just choose one randomly but if anyone has any recommendations I'd appreciate it. Thank you .
