Jonathan’s Vineyard Blog - July 2025

GODSTONE • July 1, 2025

A consequence of warm, dry Summers (such as 2025) is the prevalence in English vineyards of a disease called ‘powdery mildew’; unchecked it can devastate the entire grape crop and so vigilance is required in order to prevent it taking hold. It thrives in humid weather and especially where airflow between the vines is limited.


Powdery mildew infection appears as a white, powdery coating on leaves, stems, and fruit. If left untreated it can stunt growth, reduce fruit quality, and even affect the flavour of the wine.


Of the two varieties which we grow at Godstone the most at risk from mildew is Bacchus due to its dense canopy of foliage. Our other variety, Seyval Blanc, is fairly resistant to mildew.


The best thing to do in order to prevent mildew from taking hold is an enhanced programme of canopy management, especially leaf stripping - which significantly improves air flow around the grapes, combined with reducing the amount of foliage.


We rely upon a loyal group of friends who kindly offer their services voluntarily on several days throughout the Summer in order to help us with our canopy management and we are eternally grateful for their help.


Our vineyard will be open on three Saturdays during July and, if you would like to visit, please kindly reserve your spaces using the links below:

11th August 2026 We have been extremely busy in the vineyard, however let's talk about the weather! It's been a remarkably hot, dry Summer in Southern England, you don't need me to point that out, and we are one of the only agricultural sectors who are not suffering as a result of the relentless sunshine combined with lack of rainfall. Vines do not need Summer rainfall, in fact, dry weather is ideal because heavy rain or high humidity close to harvest causes the berries to swell and split, dilutes sugar levels, and triggers fungal diseases such as mildew. Dry Summers generally produce much higher-quality grapes. A grapevine typically requires roughly 10-35 inches of water annually to support their growth cycle, and they prefer to absorb this moisture through winter and spring rainfall stored deep within the soil. Grapevines are deep-rooting plants; whilst the majority of their roots (about 60-80%) live in the top 2-3 feet of soil, their anchor and tap roots can push down to 15-20 feet or more. At the time of writing we do not have a definitive harvest date but needless to say it will be a few weeks earlier than normal. We remain open every Saturday between now and the end of September and always love seeing you. https://www.eventbrite.com/e/summer-in-the-vines-at-godstone-vineyards-tickets-1 987770961455?aff=oddtdtcreator Regards, Jonathan & Robert

17th June 2026 June is usually a busy month in the vineyard and this year has been no exception. Firstly, bud rubbing and shoot selection has been undertaken - removing unwanted shoots from the trunk - done by hand - after which shoot selection, a critical task which is not so much about keeping the strongest shoots but more about retaining the best positioned ones. Good spacing improves airflow, reduces disease pressure, and makes future tasks more straightforward. Early thinning prevents canopy overcrowding later on. Secondly, we moved on to tucking in, because as shoots extend the main priority is keeping them upright. If done properly this tucking in enables the vines to form a neat hedge-like canopy, thereby improving light distribution and keeping the fruiting zone accessible. In July our main job will be tipping and / or topping the vines, followed by leaf stripping. I will let you know how we get on with these tasks in my next edition of these Notes. We always love to see you and the vineyard is open every Saturday until mid September - with free parking, free self guided vineyard walks, and sharing platters of carefully curated local cheeses and charcuterie, it's a lovely way to enjoy a Saturday this Summer ! (Booking is appreciated and greatly assists with our planning …) https://www.eventbrite.com/e/summer-in-the-vines-at-godstone-vineyards-tickets-1 987770961455?aff=oddtdtcreator Regards, Jonathan & Robert
