* A guess (I have not grown red gooseberry) . . . you probably have not had a significant increase in pH with 2.7% of other fruit so it is probably in the low 3’s. . . . Yeast worked so maybe 3.2 pH, expect it to taste acidic and you will need to back sweeten. My/ my wife’s taste would bring it back to 1.015 gravity or about 30 to 35 grams sugar per bottle.
* green gooseberry is fairly dry, , which means you may have 50% extraction, , therefore TA could be .7 which is good
* My guess is acid (ie taste) is stable now, yeast may have eaten some citric acid but it isn’t significant. Bulk aging will not change the acid content, citric does not crystallize out.
* My standard is age 9 months minimum, a year would be nice, , , but this is to starve the yeast and not add sorbate.
You didn’t mention meta/campden, , or tannic antioxidants , , keep up the metabisulphite every transfer.
Good luck. . . & sorry I didn’t look to see you are a gal
