About


Note:
•	May need to blend finished wine with some neutral apple, pear or white grape base wines to adjust final taste profile. I feel that if any is used, it should not be any more than 15% of the total volume.
•	If wine proves to be too astringent or tannic at stage #17, a further heavier dose of gelatin may be required to lower tannic levels.
•	Small amounts of glycerin may be required at stage #18 to add body depending on your taste
The above recipe produces a fine wine that will get anyone who tastes it to instantly fall in love with the fruit…pretty much like I did.
I would love to hear your stories on black currant wine production or take a look at your own recipe formulations, better yet, would love to taste some of your wines, just drop me a note.
Until then, happy winemaking!
