You may want to check out the post where linuxboy (Pav Cherny) comments on a culture combination like yours for Gouda and what would give a closer flavor profile to the 'real thing'
Re: Midnight Moon Goat's Milk Gouda Style Cheese
http://cheeseforum.org/forum/index.php/topic,524.msg59090.html#msg59090"One, age it out for a year. Two, change your cultures. As I wrote, midnight moon is a DL culture with multiple undefined strains, and adjuncted with what tastes like helveticus, paracasei, rhamnosus, or a blend to me. MA4001 is a D type with specified strains, modified with TA for acidification. Wrong culture. Get a classic gouda culture where you have all four (again, DL type) and make sure it's undefined strains. Hansen's CHN 11 IIRC, FD, probat, etc can all be used. And then adjunct it with bacilli. Strain selection is absolutely crucial here. You can't use something like LH100. You have to use a strain specifically formulated to give you the flavor profile you want. All the houses have these strains. Ask your local shop what they recommend for a sweet and nutty profile. Something like Danisco's FLAV series tend to work. LBC81 is fine for faster paste development and bitterness control and some flavor development, but it is not like helveticus or specific acidophilus flavors. One of danico's proprietary FLAVs, for example, their acidilacti, produces a sweet note."
I personally like Kazu + Flav 54
