釀酒人札記 - 老藤的迷思---葡萄藤的年紀當真這麼重要？

引言：
因為初入葡萄酒世界，曾經爬過文，說老藤的根比較深，可以吸收更多土裡的礦物質，讓酒的風味更多元，這是淺層新藤所無法達到的，不知對不對？

小的認為, 對也不對
開頭的文章寫到「老藤絕對不是唯一原因，種植密度也影響甚大」
如果是老藤、低密度種植, 根不一定扎得深(西班牙是一例)

至於礦物質多寡, 同樣和土壤、種植方法有關的, 根扎得深, 不一定吸收更多
比如自然動力法的配方 501 裡含有的矽石, 帶有豐富礦物質
又比如 Chablis 的白堊紀石灰岩(Kimmeridge Clay), 本就富含礦物質, 新藤淺根也吸收得到

某些情況下的確是「老藤的根較深, 可以吸收更多土裡的礦物質」
但這不是以一概全的......

您太謙虛了!

能舉出這麼精確的例子! 一定是個行家!

我個人認為! 葡萄酒是"精緻"農業的產品

有相當多的"通則" !

卻有著更多的"例外"

而那些例外或許就是吸引我們的地方吧?

小弟所學實在稱不上行家......只是愛喝的酒鬼罷了
愛喝, 想了解更多, 不知不覺就聽到不少小道消息囉

葡萄酒對小弟來說, 只是一種日常生活用的酒類, 能選擇的酒種也多
(就像小弟也愛喝清酒、啤酒、烈酒之類)
唯有 fine wines 才能走到「精緻」的程度, 但依小弟的財力, 玩不起呀~
那些「例外」也的確吸引我們這些酒鬼, 不停地嘗試......

唉~ 好窮.......

一個提問

有別於玫瑰北極熊大的“ 老幹新枝 ”。

假如是老母株接新枝枒~~~也就是“ 接枝 ”。

台灣的水果大多是接枝而來。

棗子就是用老母株接新枒的方式，才會有大的像蘋果一樣。

Mike,

我覺得您與Kenny都應該多多發表一些您們的看法!

不僅可以讓這個園地更有內容!

也可以讓我們葡萄酒的功力倍增!

感謝文章分享!

又學了很多.

好極ㄌ~!  長知識ㄌ喔~!

礦物質對葡萄樹和葡萄酒的影響如以下這篇研究報告:

EFFECT OF MINERAL NUTRITION AND SALINITY ON GRAPE PRODUCTION AND WINE QUALITY

Author:   B. Bravdo Abstract:
Crop production and quality are affected by mineral nutrition directly and indirectly. The major indirect effect is via alternation of the vigour and the capacity and thereby on the crop load. Elements such as Zn and B, affect fruit set, K and Mg affect bunch stem necrosis and thereby the number of clusters per vine and number of berries per cluster. Nitrogen affects the production and quality of the berries, must and wine both directly and indirectly. The indirect effect is via its stimulating effect on vegetative growth whereas evidences for a direct effect on proline, arginin and volatile esters in the must were reported by various authors. K affects must and wine pH whereas P was reported to affect free and bound monoterpene content of must and wine.

Modern table grape vineyards as well as wine grapes in many famous regions around the world are subject to mineral fertilisation via drip fertigation methods. Technologies developed during the last three centuries enable site specific application of water and minerals and control of the water availability and nutrient concentrations in the root zone. Since mineral uptake is a function of mineral concentration in the root zone rather than of Kg/ha application, the fertigation represent alternation of a concept, not only of technology. Irrigation with moderate saline water 1.2–4.2dS/m was found to significantly affect the content of 16 various volatiles in Cabernet Sauvignon wines. A significant rootstock effect on Cl content of petiole, blades and must as well as on wine quality was found in a saline water irrigation experiment.

Macroelements analysis of petioles represent the nutritional status of the vine better than blade analysis and there are various advantages and disadvantages for bloomtime, veraison and harvest sampling time.

礦物質也可從肥料中補充, 跟老藤新藤無直接關係.

以澳洲的葡萄園來舉例, 土壤中的礦物質含量通常會被測量 (直接或間接),

來決定是否需補充. 如以下這篇研究報告:

THE MINERAL NUTRITION OF WINE GRAPES IN AUSTRALIA

Author:   J.B. Robinson Keywords:   Grape, Vitis vinifera, mineral nutrition, fertiliser, soil analysis, plant tissue analysis, Australia Abstract:
A wide range of soils is used for viticulture in Australia. Almost all are low in plant available phosphorus and often are alkaline and low in organic matter. Most supply potassium well. Australian viticultural regions are predominantly in winter rainfall areas, and grape quality is controlled by management of the irrigation of the vines rather than nutrient availability. Drip irrigation is widely used.

Phosphorus is applied prior to vineyard establishment, and nitrogen is applied by fertigation. Micro-nutrients (zinc, manganese) are applied as foliar sprays, frequently during vineyard establishment and once or twice each year prior to flowering in mature vineyards.

In some districts, winter cover cropping with cereals or leguminous crops is common, in others a permanent sod is established. Chicken litter or NPK fertiliser are used to stimulate bulky growth. There is interest in mulching with green waste.

Soil analysis is used to define any need for basal applications of fertiliser before vineyard establishment, and later for monitoring and problem solving. Sampling the root zone of a vineyard is difficult.

Nutritional monitoring is often done by analysis of petioles collected at flowering time. There is interest in other sampling procedures aimed at getting information earlier in the season. Petiole analysis does not give a good picture of nitrogen status except in very high yielding vineyards, probably because other factors are limiting performance.

Grape growers are being targeted with a large number of new fertiliser products including liquid and solid formulations for fertigation, multi-element foliar nutrient sprays, products which contain humates, organic chelates etc.

There is interest in “organic” viticulture. In areas with dry summers it is difficult to supply sufficient nitrogen to drip irrigated “organic” vineyards.

謝謝 Charlie 大的詳盡解說!

只有四個字表達...

真是專業

感謝感謝！受益良多阿
