For those homebrewers still hesitating whether they should invest in some refrigeration capacity or not read here (Dutch - I'll translate after):

"De periode van 1900 tot 1945
Rond de eeuwwisseling telde België ongeveer 3200 brouwerijen. In de steden, maar ook in de dorpen, behoorden de brouwers door hun status, maar vooral ook door hun rijkdom, samen met de dokter, de pastoor en de notaris tot de notabelen Gebrouwen werd er in de winter; koelinstallaties waren er nog niet en daarom bracht 's zomers brouwen een te groot bederfrisico met zich mee."
Translation: "From 1900 till 1945
Round about the turn of the century Belgium had roughly 3200 breweries. In the cities, but also in the villages, brewers were, not just by their social status but in particular by their wealth, among the leading residents together with the family doctor, the priest and the notary. Brewing was done in wintertime; there were no refrigerating-plants that time and brewing in summer involved a high risk for infections."

This is all so fundamental, gentlemen. Years ago I bought a secondhand refrigerator for 25 euros. It's still working. I assure you that it was no wrong investment.
