I'd think that alcohol would still be transported, as it had demand.No problem. Glad to help
Dyes are good because they can be traded in both directions. Raw dyestuffs in exchange for finished, dyed and woven cloth. Same with minerals like cobalt. Much of the cobalt used in Chinese porcelain came from Central Asia, I think, and the finished porcelain later traveled back west along the Silk Road. I'm not sure alcohol would travel well on land. Liquid is heavy and awkward to transport in caravans.
