It tells the ground's degree of acidity or alkalinity.

Most important of all, a soil test will indicate degrees of acidity or alkalinity.

All wines need some degree of acidity in order to be balanced and avoid tasting flabby or dull.

Perhaps the greatest quality characteristic possessed by vines grown in Champagne is the ability to produce ripe grapes with a relatively high degree of acidity.

The degree of acidity of the urine shows a daily variation, nocturnal urine being most acidic.

Sweetbreads are spectacular, too, their light character emphasized by a sauce of verjuice, grapes and thyme that has just the right degree of acidity.

It had no odor, a delicious walnutty taste and utterly no aftertaste, thanks to its remarkable 16 to 18 Turner degrees of acidity.

This viticultural twilight zone stretches the duration of the vine's growth cycle to the limit, resulting in a longer ripening period, providing grapes with a high degree of acidity.

Also, depending on the degree of acidity, it may be necessary to apply ground limestone to the soil to raise the pH level so that particular nutrients are soluble and available to the plants.

This provides the reason why it was once extensively cultivated in the Aube, where its more southerly location and lack of limestone subsoil sometimes renders wines lacking the desirably high degree of acidity required for classic Champagnes.

Champagne's harvest must therefore reach a reasonable level of ripeness and as the ripening process, or véraison the French call it, increases the sugar content, the high degree of acidity necessary for these wines is important only in ratio to the sugar content.

The oils from the olive variety Verdial are sweet and fruity, and the fact that they are organic production and flight (never land with olives) make Verdial Lácara oil does not exceed 0.2 degrees of acidity, with and Extra Virgin.

The pH meter allowed chemists to measure the precise degree of acidity or alkalinity of a solution - a long step beyond the litmus paper of the past, which merely turned red in the presence of an acid or blue for an alkali, not matter how strong the solution.
