If you don't have insulin and have a load of beer then your BGs will go high. Each pint had around 15g carbs in. I don't drink beer much any more because it always makes me go high. I'll only have one if I'm in the 4 or 5s. You can take insulin for it, but you need to be careful because after a few hours of drinking you will start to drop. If you do take insulin for it, test often and have some carbs before bed.
