Flowering has started on my Pinot Noir vines. You’ll see that some of the flowers have emerged; others still have their caps on. These browning caps can cause botrytis later in the season if they remain trapped in the bunch, as they can act as a focus of infection. Organic products such as Botryzen look to colonize the decaying caps with good fungi that don’t then infect the grapes, which is a smart solution to this potential problem.
