I ordered the Reserve Chardonnay bundle for my dad's birthday (early December) and we have just finished assembling the fermentation.
I am a UC Davis trained Winemaker and work as such in Napa, CA and it is my opinion that this kit is high quality and is absolutely legit. I love that the yeast, which was described to me as being like EC1118, immediately started off-gassing when I rehydrated them in some excess juice. There are nutrients as well as malolactic bacteria (a co-fermenter to soften the harsh malic acid) in the yeast packet, making quality winemaking easy and effortless for beginners.
The real kicker for me is that there are additional clarifying agents, which are totally natural, to use after fementation to help settle out solids that you will rack off of. (Not all of us have 0.45 micron filtration ability!)
I brought with me some oak chips from my winery to add a touch of structure, aroma and mouthfeel. The options are endless with other tannin and fining products that are readily available at any fermentation shop.
I am very, very happy with this kit and I know my dad is stoked to try his Reserve Chardonnay in ~5 days!
