I am brewing my second batch, a dunkelweisen, I am using a cooler, water, ice and a towel to ''control'' the temperature, so far it is working fine, has been fermenting for one week so soon fermentation will be completed, my question is: Should I keep controlling the temperature even after fermentation, has been on 68-69 since the fermentation started, my plan is to move it to room temperature: 72-73 so I can use the cooler to brew my third batch. Any issue I should know before doing this?
