In a station with gravity equivalent to the surface of the moon or greater, go with aquaponics. Aquaponics is hydroponics with fish and bacteria included in the system. Instead of soil, you use expanded shale as the growth medium in the grow bed. Red worms live in GB and digest any dead roots or leaves, nitrobacter converts the ammonia waste from the fish into nitrite and nitrate which the plants then take up as nutrients. There are certain plants that can be grown that can provide a good portion of the food required by the fish but you may need to provide an external protein source. Black soldier fly larvae are an excellent choice here for protein as they could readily digest the food waste in the station's compost pile.

I think using this methodology would have produced a much more informative result. I'm a homebrewer and there's a definite cost for higher gravity/better quality brews. The stereotypical weak American beer from macrobreweries use a fair amount of cheap adjuncts (like corn sugar) to boost the gravity but add little to the flavor of the beer.
