new to this wine thing=)

[cluelessonwines]

hello everyone.
me and my husband have been drinking wine for about 2 years now but only recently have we really begun getting into it as hobby.
so we are still a novice and all the wines we've tried have been on "lets try and see if we like it."could anyone explain to me what i should be looking for in a wine(ive found i like zinfadels and merlots)ive read things about their ph and a brix residual sugar on websites but have no clue what this means or what level/range i should be looking for.
any info would truly be appreciated!=)
