Some warm weather has hastened flowering. Here's a shot of a Pinot Noir vine, one of the earliest to flower.
You can see the small inflorescences just beginning to show the white flowers. There is a delightful scent of honey as you walk the rows. It's important to get stable weather during the flowering period so that all the flowers can get fertilised and grow into berries.
A close-up shot shows the flowers in more detail:
I have marked this vine and I will take regular photos to show the development of berries and bunches as the season progresses. Right now, it all looks pretty good.
