Hi Katy 9 weeks is a long time for them to only produce little bunches. For mild sweet flavour lettuce need to be grown fast - that is, plenty of water and plenty of available nutrients in the soil, including plenty of available nitrogen. Otherwise they can be quite bitter. Is it possible they got too dry or that the soil was not amended before they went in? Fortnightly feeding with something like worm tea can help if you're growing in containers or still building up your soil. Lettuce also tends to become bitter if it is going to seed, but if that's the problem you would be able to see the central flower stalk forming.
