I've not noticed a geranium odor, but I detect a similar, consistent taste in all of my kit wines. Guess it's what some call "kit taste". Personally, my kit wines improved noticeably when I quit using sorbate, and took another step forward when I began barrel aging and not drinking them too young. I've got some good ones that I like, some that I don't, others enjoy them more than I. They took yet another step when I started adding pressed skins and bailed out on all chemicals except sulfite. My grape wines are just starting their barrel rotations, and are quite good already, I expect them to surpass the kits, time will tell, but the grape wines cost a lot more to produce.......
I collect and drink a lot of very nice wines, which makes me very picky, but I still enjoy my better kits as "everyday" wines, and the Mrs. likes them too.
