Use yeast strains at temperatures with ingredients known to limit higher alcohol formation? Thing is, these are fractions of a percentage differences here so at normal consumption levels it makes very little difference. Don't drink too much and don't drink on an empty stomach. If you drink too much a hangover is almost inevitable.
I used to think that the empty stomach thing made very little difference and might even leave me at greater risk of being over the limit the following day. Get it all in me, let my liver sort it out sooner? An empty stomach has faster absorption, a higher total blood alcohol concentration is reached and sooner, a greater differential is present, therefore greater losses to respiration and so on? Because alcohol metabolises at the same rate irrespective of total blood alcohol concentration it doesn't really work like that. But yeah, I believe you metabolise 0.06% per hour on average and if the rate of absorption is slow enough to be not much greater than the rate of elimination then your blood alcohol concentration will spike much lower lessening the impact of alcohol poisoning and a potential hangover. As elimination starts from pretty much the moment you start drinking total time to elimination is pretty much fixed.
The older I've gotten the less interesting being really drunk has become. I'm bored of it, I've done it enough times. The hangover is almost existential these days, why did I do that? What were the reasons? I feel disappointed more than anything, it prevents me from doing what I want to be doing, rattling around with blurred vision until 8pm the following evening. I try not to hit it like that very often!
