氷コーヒー Frozen Coffee

August has almost come to an end but it's still so hot everyday. So it's been enjoyable to drink something cold for a while.
氷コーヒー(こおりこーひー, frozen coffee) is one of my favourite drinks. It is milk with added coffee ice cubes to it. The way of making coffee ice cubes is to pour rather strong coffee into an ice cube tray and freeze it. To make coffee ice cubes poor strong coffee into an ice cube tray and freeze it. That's all! It's nice to add some sugar into the coffee as well.

Please point out any errors in my pronunciation as well.

8月ももう終わりますが、ものすごく暑い日々が続いています。そのため、しばらくは冷たい飲み物が楽しめそうです。
氷コーヒーは、わたしのもっとも好きな飲み物の一つです。これは、凍らせたコーヒーに牛乳を注いだものです。凍らせたコーヒーの作り方は、かなり濃く淹れたコーヒーを製氷皿に注ぎ、冷凍します。それで終わりです。コーヒーに砂糖を入れても、おいしいです。

Since others have already corrected everything. I'll just explain why the first line, "August almost came to an end but it's still so hot everyday.", is incorrect.

When you say something or someone "almost came", you imply that the event did not happen and the time the event should have happenned has passed. Thus, it sounds like you are saying, August nearly ended, but did not, for some reason.

When you change "almost came" (past tense) to "has almost come" (future tense), than it is clear that the event will take place in the future, and we don't have to worry about time stopping or going backwards. :)
