The Poulsard vine tends to buds early, which makes it prone to the viticultural hazard of early spring time frost. In some vintages, "coulure" can set in and affect yields (which are usually very low to begin with). Additionally the vine is very susceptible to various grape diseases including downey mildew, grey rot and oidium. These issues, coupled with its low phenolics and coloring pigments, have contributed to the grape's decline in overall plantings, though it still maintains its presence in Jura.
