Det er liten/ingen fare for at det dannes ny usmak ved å kjøle ned hurtig.
Dersom det er en sterk øl og du skal flaskekarbonere, kan det derimot være lurt å være varsom med gjæren siden den tross alt skal gjøre en siste jobb for deg på flaska

Traditional Lagering
As the fermentation slows and yeast begins to flocculate; the brewer starts to
slowly cool the beer at 0.5-1°C (1-2°F) per day until they reach about 4°C (40°F.)
Beer is then transferred into lagering tanks where it is held at this temperature
for months.
Now that fermentation is complete, including the diacetyl rest, we need to start
lowering the temperature. This encourages any remaining yeast in solution to
flocculate out. However, this cooling needs to be conducted at a rate that keeps the
yeast active for as long as possible, continuing the conditioning process. Rapid
(within 6 hours) changes in temperature of more than 3°C (5°F) (up or down) at
the end of fermentation can force the yeast to release esters and shock proteins
rather than retaining them within the cell. Therefore, slow decreases in
temperature of 1-2°C (2-4°F) per day are recommended.
Below 4°C (40°F) there is very little activity from the yeast to clean up the beer.
Therefore, the lagering time is much longer. The main benefit of going below 4°C
(40°F) is the removal of chill haze, but the availability of well modified malts and
fast-acting finings have removed the need for long cold storage.
Traditional lager conditioning times:
3-4 weeks at 7°C (45°F)
5-6 weeks at 4°C (40°F)
7-8 weeks at 2°C (35°F) Mostly unneeded due to and low yeast activity.
Note: longer lagering times are needed for higher alcohol lagers."
