The '1°' referenced in the article you linked to is written 'un grado' in Spanish. Here the symbol means 'grade' (instead of 'degree', which is also another word for the same symbol). (The same symbol is used to represent the ordinal numbers used with masculine gender, e.g., 'first' = primero = 1°.)
The grade mentioned in the article is equivalent to the percentage of acidity. So, instead of the '°' symbol, it could have also been written as '1%'. Later on in the article, you'll see such a reference (where it says that an acidity of more than 2% isn't fit for human consumption).
In Spanish, '1%' is written out as 'un porcentaje'.
