Histоne аcetyltrаnsferаses (HAT) are enzymes that result in the additiоn оf acetyl groups to histone tails. This results in [1]. While histone deacetylases (HDAC) are enzymes that result in the removal of acetyl groups from the histone tails. Meanwhile DNA methyltransferases (DNMT) are enzymes that result in the addition of methyl groups to DNA. This results in [2]. Resveratrol, which is found in grapes (and subsequently red wine) is a known DNMT and HDAC inhibitor. This would result in [3] of genes. Alcohol, however, leads to hypermethylation of DNA, which would result in [4]. Additionally, epigenetic modifications can be used to silence genes or chromosomes for the entire life of an organism.
