Seasonal adjustments for temperature is par for the course really in the case of home brewers.
A constant brewing temperature being more important than one a bit higher or lower than the desired one.
Commercial brewers have their brew rooms and vats at stable temperatures the year round.
In my case, I just adjust the distance of light bulb to brew barrel and increase or decrease the insulating layer over the brew box I use over the barrel.
It's a great hobby alright, but now I've found two or three recipes I enjoy and stick to them.
I enter a few local home brewers' competitions and always get a thumbs up for my brews, not a great prize-winner, like, more of a "Hell mate, that's a good drop!"
Good luck with your brew. good health and long life to ya.
